1. Installation Steps
GB
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 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, see fig. 2.
4.Connect the wire before mounting the back plate to the wall box using the enclosed screws, see fig 3. Then mount the cover to the back plate, see fig 4.
2. Wiring
1.Dimensions, see fig. 5
2.Wiring diagram, see fig. 6 to fig.9
3.Follow the illustrations to complete the wiring:
1)Wiring for SPST on/off control
. RC-C4, see fig. 6
. RC-C2, see fig. 7
2)Wiring for SPDT on/off control

4. Notes
1.Correct wiring is essential; using instrument to confirm 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 fix 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 connects with the screw.
4.If walls must be painted, mount the room thermostat after painting, to avoid dust or paint material penetrating the room thermostat and thus damaging the PCB.
5.The max load of relay is 3 A (resistive) or 1 A (induc-

tive). The relay will be damaged 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 actuator and valve in individual room temperature control.
