NOTE !
Read the entire instruction carefully before start.
APPLICATION
MF-HTT is a humidity and temperature transmitter/controller for the measurement and indication of
relative humidity, temperature, dewpoint and mixing
ratio. With the four keys , , PGM and ESC the
desired function is selected as well as setting and
scaling is done. The dual row LCD display clearly indicates the selected function
INSTALLATION
MF-HTT is designed to be placed on a wall or for recessed mounting through a wall or cabin door.
When recessed mounting, a mounting kit,
MFM-PANEL is used. The unit is fixed to the wall by
four screws, max 4 mm. The location of the holes is
shown at the back of the enclosure.
Unscrew the four screws of the front cover and use
the bottom screws to attach the front cover on the
upper end of the casing, see Fig 1. This makes installation and electrical connection easier.
Connect power supply according to the electrical
connection.
To each front cover the CPU is mounted, since the
I/O calibration of the main circuit board is stored on
the CPU-board, it is not possible to move the front
cover between different units.
OUTPUT SIGNAL
MF-HTT has two analogue outputs to be used for
RH, Temp, dewpoint, mixing ratio and PI-controller.
VDC or mA output signal must be set by the
DIL-switch (DIL1). The same programming must
then also be done under Outputs.

Calibration of the Humidity Sensor

HTT is equipped with a humidity sensor with an accuracy of +/- 2% RH.
The sensor is delivered with a calibration protocol
which state two reference voltage values which are
programmed in parameters '0% RH' and
'75,3% RH'.
Calibration table FACTORY must have been selected.
If the sensor is exchanged the new reference values
for the new sensor are programmed for 0 % RH and
75.3 % RH.

Calibration tables
MF-HTT include three tables to store different calibrations, default calibration table 'FACTORY' and
two user programmable tables 'USER 2P' and
'USER 1P' for field calibration.
Factory calibration
The table 'FACTORY' must be selected to apply the
calibration from factory.

Select engineering unit, type of output signal and

scaling for both Output 1 and Output 2.
q Source determines the source used for the
output signal (Humidity RH, Temperature
TEMP, Mixing ratio HR or Dew point TDP).
q Signal determines the type of output signal to
be used for the output (Volt/mA).
Note ! In addition to the programmed output signal, the DIL-switch on the main circuit board
must be set for the same output type.

2 point calibration:
Normally this type of calibration is done with a salt
solution with predefined humidity content.
q Select Cal Tbl = USER 2 P
q Place the probe in a chamber with defined humidity for the lower calibration point.
q Programme the defined value in % RH into the
parameter UsrCalPt1.
When programming is finished by pressing the
PGM-key the calibration starts for the lower calibration point.
It is important that the sensor is exposed to the
same humidity level during the entire measuring cycle that is programmed in UsrCalPt 1.

1 point calibration:
This type of calibration is possible to do with a reference instrument or similar
q Select Cal Tbl = USER 1P
q Programme the parameter SinglePt with the
value in % RH indicated by the reference instrument.

To achieve a stable control around the set

point, a neutral zone, NZ, can be programmed. Min value is 1% of the selected
source range. The neutral zone is equal on
both sides of the set point.

6.

Key lock is a hidden parameter if the function is activated and no code has been entered. This function
is available from program version 2.10 or higher.

3. The first digit (0) is flashing to indicate that the

first digit of the code must be entered by using
the arrow-keys. Press the PGM-key to jump to
the second digit, etc.

The key lock is to be used when then transmitters

settings must be protected from unwanted alteration. The 4-digit code must be entered before accessing the program and function menu. For
Micaflex with built-in control function the code must
also be entered to switch between AUTO and
HAND operation.

4. When all four digits are entered press a final

time the PGM-key. The entered code is now
compared with the settings in the parameter
'Access code'. If they match the program menu
is accessed.

Indication of the measured values and operating

state is accessible without entering the code.
At delivery the code is programmed to "0000" unless nothing else is agreed to. With factory default
code "0000" the key lock is in-active. I.e no protection for alternating the settings.
Activating the key lock
To activate the key lock settings must be programmed into the parameter 'Access code' which is
found below the parameter group 'System settings'.
The code must be different from "0000" unless the
lock will be in-active. After programming a 4-digit
code into the parameter this code must be used to
access the program and function menus.
In-activating the key lock
The key lock can be in-activated by setting the value
of parameter 'Access code' to "0000". Since the setting is done from the program menu the already
programmed code must be known to inactivate the
key lock.
Contact Micatrone if the code has been lost!
Entering code
To access the program or function menu or to switch
between AUTO-HAND function the code must be
entered.
Example to access the program menu:
1. Press the PGM-key to open the program menu.
Keep the key pressed until following screen appears.
