WT-T Room Thermostat
GB
1. Installation Steps
1. Installation must be done by an authorised
electrician.
2. The room thermostat should be installed at approx.
1.5 m above floor and where the effects of sunlight,
draught or other heat sources (eg. TV’s) are avoided,
see fig. 1.
3. First of all, carefully remove the cover and dial knob,
see fig. 2.
4. Connect the wire before mounting the back plate to
the wallbox using the enclosed screws. Then mount
the cover to the back plate, see fig. 3.
2. Wiring
See fig. 4 for dimensions and fig. 5 for wiring diagram.
WT-T is often used with a Danfoss TWA actuator.
Depending on the conditions of power location and
actuator type (NC or NO), the wiring between room
thermostat and actuator is different.
Follow the illustrations to complete the wiring.

thermostat:
• Connect to actuator TWA 230 V NC type, see fig. 6.
• Connect to actuator TWA 230 V NO type, see fig. 7.
2. When power supply location is close to actuator:
• Connect to actuator TWA 230 V NC type, see fig. 8.
• Connect to actuator TWA 230 V NO type, see fig. 9.
