INSTALLER CONFIGURATION PARAMETER MENU

• Configuration can be done through the network or locally at the Terminal Equipment Controller.
• To enter configuration, press and hold the middle button “Menu” for 8 seconds
• If a password lockout is active, “Password” is prompted. Enter password value using the “up” and
“down” arrows and press “Yes” to gain access to all configuration properties of the Terminal Equipment
Controller. A wrong password entered will prevent local access to the configuration menu.
• Once in the configuration menu, press the “No” button repetitively to scroll between all the available
parameters.
• When the desired parameter is displayed, press “Yes” to adjust it to the desired value using “up” and
“down” arrows. Once set, press “Yes” to scroll to the next parameter.

the local tenant that the door/window needs to be closed for cooling
or heating to resume.

configuration functional if binary input #1 is set to Motion NO or Motion NC or a PIR
Default value = None accessory cover is used.
With this sequence enabled, the occupancy is now dictated through those
2 inputs. Any motion detected will set the zone to occupied status. The
zone will remain permanently in occupied mode until the door contact
switch opens momentarily. The Terminal Equipment Controller will then
go in stand-by mode. If more movements are detected, the occupied
mode will resume. While the door is opened, any movements detected by
the remote PIR sensor or the PIR accessory cover will be ignored. Use a
Normally Closed contact switching device.
• Contact opened = Door opened
• Contact closed = Door closed
(RemOVR): temporary occupancy remote override contact. This function
disables the central button override function on the Terminal Equipment
Controller. The override function is now controlled by a manual remote
momentarily closed contact. When configured in this mode, the input
operates in a toggle mode.
It is now possible to toggle between unoccupied & occupied setpoints for the
amount of time set by parameter (TOccTime) temporary occupancy time.
(Filter): a backlit flashing Filter alarm will be displayed on the Terminal
Equipment Controller LCD screen when the input is energized. It can be
tied to a differential pressure switch that monitor filters
Contact opened = No alarm

(Service): a backlit flashing Service alarm will be displayed on the
Terminal Equipment Controller LCD screen when the input is energized. It
can be tied in to the AC unit control card, which provides an alarm in case
of malfunction.

Pband Adjust the proportional band used by the Terminal Equipment

Proportional band setting Controller PI control loop.
Default is : 3
Note that the default value of 3.0 °F ( 1.2 °C ) gives
satisfactory operation in most normal installation cases. The
use of a proportional band different than the factory one
is normally warranted in applications where the Terminal
Equipment Controller location is problematic and leads to unwanted
cycling of the unit. A typical example is a wall mounted unit where
the Terminal Equipment Controller is installed between the return
and supply air feeds and is directly influenced by the supply air
stream of the unit.
