BI2
Binary input no.2 configuration
Default value = None

(None): No function will be associated with the input

(Door Dry) Door contact & Motion detector: This configuration is only functional if binary
input #1 is set to Motion NO or Motion NC or a PIR 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 thermostat 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 thermostat. 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 thermostat LCD screen when
the input is energized. It can be tied to a differential pressure switch that monitor filters
Contact opened = No alarm
Contact closed = Alarm displayed
(Service): a backlit flashing Service alarm will be displayed on the thermostat 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.
Contact opened = No alarm

Contact closed = Alarm displayed

UI3
Universal input no.3 configuration
Default value = None

(None): No function will be associated with the input
(COC/NH) Change over dry contact. Normally Heat: Used when both heating and cooling
are controlled from the same thermostat output. Contact closes when cold air/water is
present. Only used and valid if system parameter (Out1Conf) is set at 2.0
(COC/NC) Change over dry contact. Normally Cool: Used when both heating and cooling
are controlled from the same thermostat output. Contact closes when hot air/water is present.
Only used and valid if system parameter (Out1Conf) is set at 2.0
(COS) Change over analog sensor: Used where heating and cooling are controlled from the
same output. Temperature in duct/pipe determines control mode (heat/cool) Only used and
valid if system parameter ( Out1Conf ) is set at 2.0
(SS) Supply air sensor monitoring: Used for supply air temperature monitoring.
Only used for network reporting of the supply air temperature.
Has no internal function in the thermostat

MenuScro

Menu scroll
Default value = On = Scroll active

Removes the scrolling display and only present the room temperature/humidity to the user.
With this option enabled, no status is given of mode, schedule and outdoor temperature.
On = Scroll active
Off = Scroll not active

C or F
Sets the display scale f the
thermostat
Default value = °F

°F for Fahrenheit scale
°C for Celsius scale

Out1Conf
Output # 1 configuration
Default is: 4.0 ( 2 control outputs,
no changeover)

Defines the type of operation needed for Output #1 (BO1 & BO2)
2.0, will limit the number of sequences of operation available from 0 to 3
Will enable heat/cool operation from the same output ( refer to wiring diagram )
4.0, can access all the sequences of operation from 0 to 5
Will enable heat/cool operation from different output ( refer to wiring diagram )

CntrlTyp
Control type for Triac models
Default is: Floating

Defines the type of control output for the type of valves installed VT7200C10xx only
On/Off is for normally opened or normally closed 24 Vac 2 position valves
Floating is for modulating 3 wires control of 24 Vac floating valves
