2. Installation instructions
The thermostat is designed for flush mounting in the room to be controlled.
It should be located where the occupant can easily read the LCD display and use the controls.
If the built in temperature sensor is being used the unit should be placed where the temperature is representative
of the general room conditions.
Cold or warm air draughts; radiant heat and direct sunlight should be avoided.
The standard height to install this unit is 1.5 meter (5 feet) from the floor.
Installation procedure:
1. Disconnect power to the unit.
2. Connect the wires as shown in the enclosed wiring diagram.
All terminals accept 1x0.5mm2/24 AWG.
3. If needed, change DIP switches position.
4. Install the panel in the electrical box (Gewiss Box - GW 24 203).
5. Tighten up the 2 screws.
6. Adapt the front frame-panel into its place, by pushing it towards the wall.

Risk of Electric Shock and Property Damage. Disconnect each of multiple power supplies before
making electrical connections. Contact with components carrying hazardous voltage can cause
electric shock and may result in severe personal injury or death.
The integrated circuits in the controller are sensitive to static currents.
Take suitable precautions.

5. Temperature sensors connection and logic (T1 & T2)
Important – Use only an approved NTC 50K@25ºC external sensor with the following characteristics.
N.TC. Sensor; Temperature ~ Resistance Characteristics
Temp °C 7.2 10.0 12.8 15.6 18.3 21.1 23.9 26.7 29.4 32.2

Temp °F 45 50 55 60 65 70 75 80 85 90
T1 - External (Return air) sensor connection – option
T2 – Change over sensor
- Disconnect power and connect the temperature sensor to the unit (T1 to T1-0 terminals, T2 to IN1,0 terminals).
- Reconnect power.
- For T1 External sensor change technician parameter 6.15 to “E” (external sensor).
- For T2 Change over sensor change technician parameter 6.9 to “bO” and 6.10 to “EF”.
- For T1, Check the temperature readings and if needed use technician parameter 6.5 to adjust the offset for
calibration of ambient temperature.
Note: The length of the sensors cable is 100 feet (30 meters) with standard cable.
If longer distance is needed then the cable MUST be shielded.
