1. Installation Steps
User Guide can be downloaded from: heating.danfoss.com.
1. Installation must be done by an authorised
electrician.
2. The room thermostat should be installed at approx.
1.5 m above oor and where the eects of sunlight,
draught or other heat sources (eg. TV’s) are avoided,
see g. 1.
3. First of all, carefully remove the cover, see g. 2.
4. Connect the wire before mounting the back plate to
the wall box using the enclosed screws. Then mount
the cover to the back plate, see g 3.
2. Wiring
Dimensions, see g. 4. Wiring diagram, see g. 5 (S1, S2:
oor sensor terminals).
WT-D/P is often used with Danfoss TWA actuator.
Depending on the conditions of power location and
actuator type (NC or NO), the wiring between room
thermostat and actuator is dierent.
Follow the illustrations to complete the wiring:
1. When power supply location is close to room
thermostat:
• Connect to actuator TWA 230 V NC type,see g. 6.
• Connect to actuator TWA 230 V NO type, see g. 7.

2. When power supply location is close to actuator:
• Connect to actuator TWA 230 V NC type, see g. 8.
• Connect to actuator TWA 230 V NO type, see g. 9.
3. Error codes
Display Description
E1 Room sensor failure
E2 Floor sensor failure
4. Notes
1. Correct wiring is essential; using instrument to con-
rm L and N before wiring is recommended.
2. Don’t remove too much of the insulation cover from
the wire to avoid short circuit caused by the naked
wire touching the metal 86 size mounting wall box.
3. Don’t let the screw press or touch the wire when
using screw to x room thermostat in wall box. A
short-circuit risk exists if the wire insulation cover is
damaged by the screw, and if the naked wire con-
nects with the screw.
4. If walls must be painted, mount the room thermostat
after painting, to avoid dust or paint material pen-
etrating the room thermostat and thus damaging
the PCB.

5. The max load of relay is 3 A (resistive) or 1 A (induc-
tive, such as pump, motor). The relay will be dam-
aged if the load exceeds the limit.
6. Don’t cover the thermostat, for instance by hanging
towels directly in front of it.
7. The room thermostat should be connected to the
corresponding loop actuator in individual room
temperature control.
