Settings on PC Board Mode Selection
Jumper (JP1) on RUN:
Thermostat is in Operation mode.
Thermostat must be set in this mode to operate
properly.
If not locked, set point and control mode (Heating &
Cooling ON, Cooling only ON or Heating only ON)
may be modified by the end user.
Jumper (JP1) on PGM:
Thermostat is set in Programming mode.
Refer to the following section more details
Programming Mode
When in this mode this symbol is displayed. Please press on button to advance to the next program function and press on or
to change value. You can exit programming mode at any time, changed values will be recorded.
Step Display Description Values
1
Internal temperature sensor Calibration:
Display switches between “tS1” and temperature read by internal
temperature sensor.
You can adjust the calibration of the sensor by comparison with a known
thermometer. For example if thermostat has been installed in an area where
temperature is slightly different than the room typical temperature
(thermostat place right under the air diffuser).
Range : 10 to 35ºC [50 to 95ºF]
Increment:1ºC [1ºF]
NOTE: This thermostat has been
calibrated at factory
2A
Locking the set point :
Display switches between “LOC” and “Stp”.
You can lock or unlock the set point adjustment by end user. If locked the
lock symbol will appear.
If you do not want to lock set point adjustment by end user, go directly to
step #3.
Default value: Unlocked

Note: This value must respect the temperature range of the selected temperature sensor. Set to internal or
external at step #11A (for range, see Technical Data table on page 1).
Note: If set point adjustment has been locked, symbol will be displayed.
3
Night set back (NSB) :
When thermostat is in night set back mode, NSB symbol is displayed, so set point for cooling and/or heating
are increased as per the setting made in programming mode.
If not locked, night set back can be derogated for a predetermined period by pressing onto any of the 3 buttons.
During period of NSB derogation the symbol will flash. If NSB does not flash, the derogation period is finished
or the Night set back derogation has been locked in programming mode.

Control mode selection :
To verify which control mode is set, press once onto the button. Control mode will be displayed during 5
seconds.
To change of control mode, press on or while control mode is displayed. You can choose one of the
following:
Automatic Cooling or Heating
