SECURE MODBUS® COMMUNICATION

For SV2 Series valve configuration and monitoring, Modbus
communication utilizing an RS-485 BUS is used.

The SV2 Series valves include a Honeywell-specific secure Modbus

protocol. Standard Modbus RTU protocol is used, however, safety-
related and writable parameters are covered by a secure layer. As a
result, they are only writable when accessed using a valid user access
level and an appropriate user interface, which are designed to work
with the secure layer. Read only Modbus addresses can be accessed
without the Honeywell user interface or the secure Modbus layer

Premix Pulse Lines

The Fuel/Air Module, which is attached to the valve, contains three pulse line connections for connection of air pressure, gas
pressure and reference pressure of a gas/air mixing unit. The connections are indicated by A (gas), B (reference) and C (air).
Corresponding connections exist on the SV2 Series mixing units as well. Refer to Fig. 15.

Fig. 15. FARMOD pulse line connections/mounting.

23 32-00018—09
SV2 SERIES SAFETY SHUT-OFF VALVES INSTALLATION INSTRUCTIONS

The pulse line tubing can be plastic or metal, depending on the connection point and approval body requirement. The
Honeywell preferred pulse line connection for the reference pressure is aluminum or stainless steel. Honeywell offers several
pulse line kits with separate tubing and fitting selections, as shown in Table 2, to facilitate myriad system configurations.
IMPORTANT
–– The Fuel/Air Ratio Module operates properly only if the pulse line fittings are properly tightened and the flow through the
pulse lines is un-obstructed.
• Proper measures shall be taken to ensure the pulse lines are not twisted or kinked during connection and that they can’t
be unintentionally kinked after the installation has been taken into operation.
• Protect pulse lines against damage and keep the lines free from any contact to potential vibrating surfaces
–– In all cases, avoid creating a siphon-like shape.
–– A wide variety of pulse line slopes and shapes may be needed to fit into a particular appliance; best engineering practice
would be ‘1/2 bubble’ on a level (¼ inch of drop per 1 foot of run or 6mm drop per 0.31m of run). However, practical
limitations may require some deviation from it. Please consult Honeywell Thermal Solutions with your particular
geometrical arrangement if at doubt.

DO NOT USE.

Fig. 16. V2MU mixing unit pulse line connections.

IMPORTANT (Refer to Fig. 16)

–– To avoid condensate from back draft entering any pulse line of the Fuel/Air Ratio Module, downwards pointing pressure tabs
on the V2MU mixing unit or any other device shall not be used.
–– Partial blockage of the air intake of the V2MU mixing unit can potentially influence the air pressure signal to the valve.
• Proper measures shall be taken to avoid a partial air intake blockage of the V2MU mixing unit. Inspection of the V2MU air
intake shall be part of the annual maintenance of the appliance.
NOTE: If the appliance is equipped with a sealed air chamber and the SV2 Series valve with FARMOD (Fuel/Air Ratio Module)
is contained in the sealed chamber, it is allowed to not use the air pressure pulse line.
Attach the pulse lines to the pulse line fittings to Port A, B and C of the FARMOD as indicated in Fig. 3, following the instructions
of the burner or boiler manufacturer. Attach each pulse line to its corresponding fitting on the mixing unit or burner.

Premix Air Pre-Filter

The air pre-filter is included with every premix valve and is available as a field replacement part as well. The air pre-filter MUST
be installed in every premix system, regardless of whether the Heat Exchanger is used. The filter is designed to remove fine dust
particles from the air stream to the premix valve FARMOD, which can collect at the internal FARMOD orifice entrances, affecting
flow resistance to the internal sensors and eventually cause nuisance lockouts.
The filter must be mounted between the V2MU mixing unit and the valve FARMOD in the air pulse line. When the Heat
Exchanger is used, it must also be mounted between the V2MU mixing unit and the valve FARMOD, with the Heat Exchanger
first and the filter second. Refer to Fig. 17.
NOTES:
–– Due to the variety of possible appliance configurations, the fittings and tubing must be ordered separately. Refer to Table 2
for available part numbers and descriptions.
–– The customer must furnish an appropriate filter mounting bracket for their chosen location.

32-00018—09 24
 SV2 SERIES SAFETY SHUT-OFF VALVES INSTALLATION INSTRUCTIONS

IMPORTANT
–– The filter should be mounted as close to the valve FARMOD as possible.
–– Replacement of the filter shall be included in the annual appliance maintenance procedures.

Fig. 17. Premix installation with valve, mixing unit, pre-filter, heat exchanger and FARMOD insulation.

Premix Outdoor Air Installations

WARNING
Direct water ingress (e.g. from mist, rain or pressure wash)
into the pulse lines should be avoided or prevented
IMPORTANT:
–– When the valve is installed in an area with a temperature continuously lower than the combustion air intake temperature,
a risk of condensate formation in the air pulse line is present, which can affect the fuel/air ratio control, depending on the
appliance and permanently damage the FARMOD and the system.
–– In this case it is strongly recommended to install the Honeywell SV2 Series HEATEXCHANGER-000 kit for a complete
condensation/dehumidification solution to avoid permanent damage to the FARMOD and the system.
–– When using the Honeywell HEATEXCHANGER-000 kit, the valve + FARMOD may be installed above or below the mixing unit
+ Heat Exchanger, but above is preferred.
–– If the potential for condensation exists and the full Honeywell dehumidification system is not used, Honeywell cannot
provide any guidance regarding the valve/FARMOD position versus the mixing unit as this configuration has not been
designed or tested.
–– To prevent condensation formation due to back draft, it is recommended to purge the application after each burner
operation.
–– If there is never a risk of condensation, meaning the ambient room temperature is above the combustion air dew point at
all times, the complete dehumidification system is not needed. In this case the valve + FARMOD can be mounted above or
below the mixing unit.
The heat exchanger can be directly mounted to the V2MU mixing unit as shown in Fig. 17 and can be mounted in either a
vertical or horizontal position, depending on the appliance configuration and available space. For remote mounting the heat
exchanger, the customer must provide the appropriate bracket and/or install and connect as part of their appliance offering.
Pulse line tubing and fitting between the mixer and heat exchanger is then required.
The inner diameter of the connection between the heat exchanger and the mixer shall not be smaller than 9mm at any point.
NOTES:
–– The Heat Exchanger must always be mounted in a position that allows condensate to drain to the mixing unit. Accordingly,
ensure that the mixer connection on the heat exchanger is the lowest point in regards to the heat exchanger mounting,
otherwise water will be trapped inside the heat exchanger and will not drain appropriately.

SV2 SERIES SAFETY SHUT-OFF VALVES INSTALLATION INSTRUCTIONS

–– Excessive moisture can partially or fully clog the pulse lines between the mixing unit and the FARMOD and damage the
FARMOD. In this case, the system will fail safely by causing a flame out, a valve lockout and/or may render the FARMOD
unusable. Note that the FARMOD is field replaceable should this last instance occur.
–– The Heat Exchanger and the filter must be mounted between the V2MU mixing unit and the FARMOD, with the Heat
Exchanger first and the filter mounted as close to the FARMOD as possible. Refer to Fig. 17.
–– For detailed installation instructions, refer to the Premix Accessories installation instructions, document 32-00180, which is
available online and shipped with every Heat Exchanger.
–– Refer to the V2MU Mixing Unit installation instructions, document 32-00044, which is available online and shipped with
every V2MU.

Installation Sequence
The sequence of installation for the premix accessories is as follows; FARMOD insulation shoe (part of heat exchanger kit), heat
exchanger, air pre-filter with pulse line tubing in between as required.
For detailed installation, refer to the Premix Accessories installation instructions, document, 32-00180, which is packed with the
air pre-filter, heat exchanger, tubing and fitting kits.

Premix Start-Up
For detailed programming instructions via the HMI or PC Tools, refer to the valve user manual, document 32-00029, or the HMI/
PC Tool user manual, document 32-00031. Both are available online at https://customer.honeywell.com.
IMPORTANT:
–– The FARMOD (Fuel/Air Ratio Module) is standard equipped with a heating device. The heater will be powered whenever the
valve electronics are powered. The FARMOD will feel warm after 1 hour of being powered. This is normal.
–– As part of the appliance adjustments during commissioning, the site-specific calibration of the SV2 Series valve/appliance
should be performed when the valve/appliance has reached a typical operating temperature for its installation/application
in order to minimize the impact of component temperature changes on the fuel/air ratio.

Note that the SV2 Series valves have unique line voltage, limit, interlock and VPS (valve proving system) wire routing. SV2 Series
valves require line voltage power input at all times to the internal electronics This is true of all SV2 Series valve models. Interlock
wiring is run through all valve models for solenoid power saving feature. Interlock dry contact intput/output also used for flame
safeguard control ILK string with the Pressure Module for low gas pressure and high gas pressure functions. VPS switch contact
output present on applicable models when the Pressure Module is used for VPS that is externally triggered by a separate device.
Refer to Fig. 24 through Fig. 33 for proper valve wiring.
NOTE: Even when external C6097 pressure switches are used, the ILK wiring must be run through the valve.

Certain models of the SV2 Series valves also have Modbus interface wiring as well as termination and bias resistor selections.
The Modbus interface is used for programming intelligent features and connection to a building automation system.
Fig. 22 shows all of the wiring terminals inside the valve electronics enclosure. The factory wiring terminals can be found

1. Run line voltage wires in separate conduit.

2. Run low voltage wires in separate conduit. For the best Modbus communication performance, use shielded wire with two twisted pairs (Belden 9842 or
equivalent). Connect + and – to one twisted pair, and C to both wires of the other twisted pair. Connect the shield to Earth Ground at the end of the connected
external device (i.e. HMI or building automation system). Do not connect C to the shield. Route any noise producing wires in conduit separate from the HMI and
as far away from the HMI as possible. For further Modbus wiring information, refer to HMI installation instructions, document 32-00030.
3. MV2 and MV1 may be jumpered if there is no need to individually power them. MV2 and MV1 should NOT be jumpered if an external VPS control is used, which
requires MV2 and MV1 to be powered individually. On valve models with internal VPS functionality, MV2 and MV1 may be jumpered as the VPS sequence is
directed by the valve itself, rather than an external control.
4. Installation, operation and maintenance shall conform with National Fire Protection Association standards, national and local codes and authorities having
jurisdiction.
5. Use of the Pressure Module is only applicable to valve versions with embedded intelligence;
–– 6 = STANDARD. Includes Modbus, Pressure Module, external VPS using Pressure Module.
6. Rating may be valve supply voltage dependent.

Table 8. Field Wiring and Terminal Designation4.

D. String Wires
You will need to remove the electrical connectors from the accessory box as well any line / low voltage nuts and plugs and low
voltage cord grips. Inclusion of these items is model dependent. Complete this step BEFORE wiring to the electrical connectors.

F. Valve Modbus Bias Setup

The SV2 Series valve can communicate via Modbus RTU communication with any compatible device. Only RTU communications
with 1 start bit, 8 data bits, 1 stop bit and no parity is supported.
When more than one SV2 Series valve is connected to the HMI or PC Tools or directly connected to a building automation
system, the Modbus termination and bias resistors should be adjusted appropriately. The resistors can be found inside the
electrical enclosure on the right-hand side and are present in all intelligent valves models; valves where the 9th digit in the part
number string are 6. Refer to Fig. 22.
The TERMIN. (termination) resistor in the ON position helps to improve signal integrity for the best performance in regards to
EMC (electromagnetic compatibility). The termination resistor may be especially helpful to improve communication when the
SV2 Series connected valve is at the end of the communication BUS.
The BIAS resistors in the ON position provide differential resistance for some older communication systems where
communication can be lost with zero voltage present on the BUS. Resistors 1 and 3 should always be in the OFF or ON positions
together. Refer to Table 9.
NOTE: If communication is problematic with all daisy-chained valves connected to the master control, adjusting the two BIAS
resistors may solve the issue.

G. Install Plugs
For any remaining unused wire entry locations in the NEMA 4 / IP66 electronic enclosure, install plugs and associated nuts to
ensure enclosure rating. There are two different sizes of plugs for line and low voltage. The proper size and tightening torques
are shown below.
a. Low voltage, M16 x 1.5: 3.7 to 4.2 Nm (33 to 38 in-lbf).
b. Line voltage, ½ in. NPT: 4.5 to 5.1 Nm (40 to 45 in-lbf).

 SV2 SERIES SAFETY SHUT-OFF VALVES INSTALLATION INSTRUCTIONS

Burner Control Interface Wiring

IMPORTANT:
– If the burner management control does not have a running or lockout interlock input, consult the factory. The valve
ILKIN terminal must be powered before MV1 and MV2 valve seats can be opened or a lockout will occur. The valve ILKIN
terminal must be tied to the burner management control in some manner and not simply jumpered to L1 power.
– For the best Modbus communication performance, use shielded wire with two twisted pairs (Belden 9842 or
equivalent). Connect + and - to one twisted pair, and C to both wires of the other twisted pair. Connect the shield to
earth ground at the end of the connected external device (i.e. HMI, PC or building automation system). Do not connect
C to the shield. Run any noise producing wires in conduit separate from the HMI Tool and as far away from the HMI as
possible. For further Modbus wiring information, refer to the HMI installation instructions, document 32-00030.

Valve Operational Notes

After valve terminals MV1 and MV2 are powered, the valve will run internal self-diagnostics on its MV1 contact for 200-300
milliseconds and then close the contact to power the valve seats.
All SV2 Series valves have a power save feature built in. The ILKIN / ILKOUT circuit is used as a back-up to shut off the valve
through the burner control ILK circuit. If for any reason the power save feature fails, the valve internal ILK contact is opened and
a fault annunciated.
The valve internal ILK contact is closed at all times when the valve electronics are powered, unless there is a general fault
condition, a Lo-Gas / Hi-Gas pressure lockout condition from the Pressure Module, or just after power-up before internal relay
diagnostics are complete.
The valve POC (Proof of Closure) output terminal is energized when both valve seats are sensed closed and open if one or both
valve seats are sensed as not closed. On BASIC and STANDARD electronics versions, the valve POC output will remain energized,
even during a valve lockout condition.
When using the Pressure Module for the Lo-Gas / Hi-Gas limits, the software is only active after both MV1 and MV2 valve seats
are powered.

North American Standards 7800 SERIES Operational Notes

The North American Standard EC/RM78xx controls ILK (Interlock) input must close by 10 seconds into pre-purge otherwise a
recycle to the beginning of pre-purge will occur or a safety shutdown, depending on the model. The ILK input is ignored during
post-purge.
The pre-ignition input terminal (via the valve POC output) must remain closed during standby through pre-purge otherwise the
control returns to the standby state and hold for 30 seconds or a safety shutdown occurs, depending on the model.
The pre-ignition input terminal (via the valve POC output) must be closed within the first 5 seconds of post-purge or the burner
control will lockout.
If the SV2 Series Pressure Module Lo-Gas / Hi-Gas limits are set to auto reset and one of them are tripped during the burner
control Run cycle on a burner control with lockout interlocks, the burner control will lockout on ILK lockout and need to be
manually reset. This occurs since the Pressure Module is located in the ILK circuit of the valve and burner control instead of the
Limits circuit.

European Standards 7800 SERIES Operational Notes

The European Standards EC/RM78xx controls LOS (Lockout) input is monitored at all times for closure and will lockout if the
input opens, but will continue post-purge if it opens during that sequence.
The pre-ignition input terminal (via the valve POC output) must:
- not be open an accumulative time of 30 seconds during standby
- remain closed during pre-purge through pre-ignition
otherwise a safety shutdown occurs.
At this time, the Pressure Module cannot be used for Lo-Gas / Hi-Gas limit operation on European 7800 SERIES models.

European Burner Controls

European Standards (CE, EN, etc.)
Certain European burner controls do not have separate interlock circuits. The SV2 Series valves require that the ILKIN terminal
be tied to the burner management control is some manner and not simply jumpered to L1 power.
Burner controls with independently switched line and neutral voltages will not work as is with the SV2 Series valves and require
extra components plus wiring to make them work effectively with the SV2 Series valves.
As well, per European standards, the burner management control used shall have two line voltage switching elements in
series that switch power to the valve coils. If the burner control does not have two switching elements in series, the following
alternatives may be used in the European Union, per KIWA.
For systems where VPS is not used, MV1 and MV2 may be jumpered and powered together.

Option 1
Add an external safety relay to ensure that both the switched L1 and L2 (Neutral) of the burner control are used.

Option 2
Alternately, a transformer may be used. The transformer must be a double- or reinforced-isolated separation transformer, so
that a short between the primary and secondary is excluded. EN298:2012 Annex E requires the use of either an EN61558-
2-6 or EN61558-2-16 approved transformer, however, the actual meaningful requirement is the isolation strength of the
transformer and not the fact that the secondary is an accessible voltage.
• Use a 240/240VAC transformer
• ILKIN is only energized if both relays are ON
• Transformer may also be used to convert 240/120/24VAC as desired. Match to appropriate SV2 Series valve model
(24/120/240 VAC).
NOTE: EN61558-2-6 specifically requires that the “secondary does not exceed 50 VAC or 120 V ripple-free VDC”, whereas
EN61558-2-16 does NOT have such a requirement. In this case, ONLY the reinforced isolation is relevant.

European Burner Controls

European Standards (CE, EN, etc.)
Some European burner controls have low voltage limit and/or VPS terminals, which differs from the line voltage load terminals.
The wiring diagram below addresses wiring of such controls with the SV2 Series valves.
Certain European burner controls do not have separate interlock circuits. The SV2 Series valves require that the ILKIN terminal
be tied to the burner management control is some manner and not simply jumpered to L1 power.
Burner controls with independently switched line and neutral voltages will not work as is with the SV2 Series valves and require
extra components plus wiring to make them work effectively with the SV2 Series valves.
As well, per European standards, the burner management control used shall have two line voltage switching elements in series
that switch power to the valve coils. If the burner control does not two switching elements in series, the following alternatives
may be used in the European Union, per KIWA.
For systems using VPS, MV1 and MV2 must be powered separately.

4 VALVE CHECKOUT AND OPERATION

WARNING
Explosion Hazard and Electrical Shock Hazard.
Can cause explosion, serious injury or death.
• Do not allow fuel to accumulate in the combustion chamber for longer than a few seconds without igniting. An
explosive mixture can result.
• Do not put the system into service until you have satisfactorily completed the following Valve Seat Leak Test,
all applicable tests described in the Checkout section of the flame safeguard control manual, and any other
tests required by the burner manufacturer.
• All tests must be performed by a trained, experienced combustion service technician.
• Close all manual fuel shut-off valves as soon as trouble occurs. After the installation is complete, perform the
Valve Seat Leak Test before putting the valve into service.
NOTE: In order to complete the leak test procedure outlined below, it is necessary to energize the valve seats. Valves with
intelligent features can be readily energized if the Installer + OEM passwords have already been assigned, thereby
removing faults associated with un-assigned passwords.
For an un-programmed valve, the user must log in with the default OEM password and/or assign Installer + OEM
passwords in order to bypass the fault conditions associated with un-assigned passwords in order to energize the valve
seats. Default passwords are automatically pre-filled in the appropriate field during the initial user login.

A. Valve Connection and Accessory Leak Test

IMPORTANT
Leak check should be performed only by trained, experienced combustion service technician during the initial startup of
the burner system, or whenever the valve is replaced. It is recommended that this test also be included in the scheduled
inspection and maintenance procedures.
1. Gather required items:
a. Rich soap and water solution
2. Close the downstream manual gas valve(s), if present (refer to NOTE below).
3. Open the upstream manual gas valve(s).
4. Energize the valve train to apply gas pressure. Make sure no gas is released downstream to the burner.
5. Test with rich soap and water solution to make sure there is no leak at any pipe, flange, adapter, accessory module or valve
mating surface.
6. De-energize the control system to make sure no power goes to the valves.

NOTE: If downstream manual gas valve(s) not present, only open/power SV2 Series valve V1 and check for leaks. Recheck for
leaks on complete system when operational.

51 32-00018—09
SV2 SERIES SAFETY SHUT-OFF VALVES INSTALLATION INSTRUCTIONS

B. Valve Seat Leak Test (Refer to Fig. 35)

IMPORTANT
This is a test for checking the closure tightness of the gas shut-off valve. It should be performed only by trained, experienced
combustion service technicians during the initial startup of the burner system or whenever the valve is replaced. It is
recommended that this test should also be included in the scheduled inspection and maintenance procedures. Refer to Fig. 35.

WARNING
Electrical Shock Hazard and Explosion Hazard.
Can cause explosion, serious injury or death.
Remove the power from the system before beginning the valve leak test to prevent electrical shock. More than one
disconnect may be involved. Power the system only when requested in the test procedure.

VALVE INTERFACE
The valve interface contains 8 back lit LEDs, which are used to indicate the following conditions; valve seat open / closed or
powered / not powered status, the presence of a general fault condition, low gas pressure or high gas pressure fault condition or
if a self-test is in process.
The valve seat Open / Closed LEDs indicate the status of the valve seat over which they are situated 1.
The valve interface also has a push Reset button, which is used to reset the valve in the event it is in lockout status, to verify
safety parameters after setup and to reverse the Open / Closed LEDs when the valve electronics orientation is changed in the
field (refer to Note 1 below).

1. Valve electronics orientation is ordered as left-hand or right-hand mounted from the factory (defined as being viewed from
the valve gas outlet / burner end). If the electronics orientation is changed in the field (as illustrated in the SV2 Series User
Manual 32-00029), the LED orientation procedure must be completed to ensure the LED annunciation continues to indicate
status of the valve seat over which it is situated. This procedure is part of the instructions in the SV2 Series User Manual for
changing electronics orientation.

PASSWORD RESET FEATURE

Valves are shipped with default main OEM and Installer passwords pre-configured. These passwords have to be changed before
the valve can be used in an application without user observation.
NOTE: The OEM can choose to create the Installer password or allow the Installer to assign it during their initial login.
Additionally, the OEM must assign a reset password for their OEM level usage.
Should the Installer and/or OEM main access level passwords be lost, password reset is possible, if the reset mechanisms were
enabled by the OEM. The reset mechanism will vary between the Installer and OEM levels as indicated below. Note that cycling
of the valve or user interface power will not defeat this methodology.
NOTES:
–– The reset password/code simply allows the appropriate user to reset the current password back to the Honeywell factory
default value. Once the password is reset, the user can then log in and assign new password(s).
–– After password reset to the default value, if the affected OEM / Installer main and OEM reset passwords are not set to new
non-default values, the valve will be in lockout status and will not operate unless the OEM user is logged in. The applicable
password(s) must be configured in order to clear the fault code(s).

SV2 SERIES SAFETY SHUT-OFF VALVES INSTALLATION INSTRUCTIONS

Installer Reset
An Installer level 12-character random code is generated at the factory, which is only applicable to a particular valve serial
number. That code is placed on a card which is shipped with the valve in the accessory box. If the card should be lost, the code
is also placed on the back of the valve main electronics assembly.
NOTES:
–– The OEM can choose to enable or disable the Installer password reset function.
• If it is enabled, the Installer can follow the reset instructions below.
• If it is disabled and the main Installer password is lost, the Installer will not be able to reset the main password and will
effectively be locked out of editing the valve.
• In order to make editing possible, the OEM would have to login and enable the Installer password reset function or set a
new Installer password.
–– To access the Installer reset code on back of the valve main electronics assembly:
• First remove power to the valve.
• The tamper evident seal must be broken. Write the applicable code for reference after re-powering the valve.
To reset the Installer main password, access the valve using either the HMI Tool touchscreen display or the PC Tool. Select the
appropriate access level and password type. Enter the 12-character random code as requested. Change the Installer level main
password as requested.

OEM Reset
At the factory, the OEM will assign a main and a reset password for the valve. These 2 passwords cannot be the same. However,
the reset password could be the same for all individual OEM valves/appliances.
NOTES:
–– The OEM can choose to enable or disable the OEM password reset function.
• If it is enabled, the OEM can follow the reset instructions below.
• If it is disabled and the main OEM password is lost, the OEM will not be able to reset the password and will effectively be
locked out of editing the valve at the OEM level.
• If the Installer level main password is known, the OEM can access the valve using it and edit the parameters open to the
Installer level.
• In order to make OEM level editing possible, the valve main electronics would have to be replaced and the valve
completely re-programmed at both the OEM & Installer levels.
To reset the OEM main password, access the valve using either the HMI Tool touchscreen display or the PC Tool. Select the
appropriate access level and password type. Enter the OEM-assigned reset password. Change the OEM main level password as
requested.
Refer to the HMI/PC Tool User Manual and the SV2 Series Valve User Manual, documents 32-00031 and 32-00029, for detailed
information regarding the OEM and Installer access level password assignments and the password reset feature. Both are
available online at https://customer.honeywell.com.
