- This product should never be touched or operated with wet hands. There is a risk of a life-threatening electric shock!
- Never pour any liquids above or next to the product. You run the risk of causing a fire or a fatal electric shock!
If any liquid has still managed to enter the device, immediately turn off the mains supply at all poles (turn off the automatic circuit breaker or remove the fuse, then switch of the residual current operated circuit breaker of the associated circuits). Contact a specialist. Do not use the product any longer.
- Use the product only in a temperate climate, never in a tropical climate.
- Do not use the product if it is damaged. There is a risk of a life-threatening electric shock!
- If it can be assumed that safe operation is no longer possible, the product must be turned off and precautions must be taken to ensure that it is not used unintentionally. Do not touch the product or any device connected to it.
First switch off the mains voltage to all poles (switch off the connected circuit breaker or remove the fuse and then switch off the connected RCD).
- Safe operation can no longer be assumed if:
- the product shows visible signs of damage
- the product does not work at all or works poorly (leaking smoke or a smell of burning, audible cracking noises, discolouration to the product or the adjacent surfaces)
- the product was stored under unfavourable conditions
- it was exposed to heavy loads during transport
Preparations for connection and installation
- The device must be voltage-free during installation and connection.
Switch off all the poles of the mains cable by removing the corresponding fuse or switching off at the circuit breaker. Then, also switch off the associated ground fault circuit interrupter (breaker). Secure it against unauthorised reconnection, e.g., with a danger sign.
- Check that the mains leads are without current, e.g., by means of an appropriate tester.
- Select an appropriate installation location.
To ensure the room temperature controller functions without fault, it must be installed so it is not close to heaters, windows, doors, air discharge openings, etc. Also keep the room temperature controller out of drafts.
Do not mount the room temperature controller behind furniture or curtains.
Because the exterior walls of a building are generally colder than the walls in the interior of the building (depending on the building insulation), the room temperature controller should not be mounted there.
Wall heaters work with air convection. Thus, warm air rises from the heater, cools slowly and sinks back down on the other side of the room. Therefore, an ideal location for installing the room temperature controller is on the wall opposite a heater; see figure.
The ideal installation height is approx. 1.5m
Installation and connection
Pay attention to the chapter "Safety instructions" and the chapter "Preparations for connection and installation".
- First, switch off the mains voltage to all poles.
- Pull off the control knob of the room temperature controller; it is only loosely attached.
-
Remove the two cross-head screws and remove the cover.
-
The bottom plate with the room temperature controller can be installed directly on an in-wall power socket via the fastening holes using screws (distance between holes/screws 60~mm ).
Fasten the room temperature sensor in such a way that the on/off switch is located at the bottom right.
Depending on the wall surface, the room temperature controller can also be secured to the wall with appropriate screws and wall plugs.
Make certain when drilling and tightening the screws that no cables or pipes are damaged!
Before installation, run the power cable and the connection cables to the load to be connected through the opening next to the screw terminals.
- Now connect the mains cable and the connection cable with the load. The number of the contact allocation can be found next to the screw terminal.
The following circuit shows the connection of a heater.
During later operation and when the room temperature controller is switched on (sliding switch in position "ON"), the heater ("LOAD") is activated when the temperature falls below the set value.
The heater is switched off again when the desired temperature is reached.
The dashed lines indicate the connection of the integrated control light. In the circuit diagram shown above, the control light is activated when the electric load is switched on.
If an air conditioner is to be controlled with the room temperature controller, it must be connected to terminal 3 (instead of terminal 2).
During later operation and when the room temperature controller is switched on (sliding switch in position "ON"), the air conditioning ("LOAD") is activated when the temperature exceeds the set value.
The air conditioning is switched off again when the desired temperature is reached.
To avoid too frequent or quick successive switching processes, the air conditioning should have a protection circuit.
- Replace the cover correctly and secure it with the two fastening screws.
- The rotating range of the control knob can be limited.
To do this, you can move the two small white plastic pins (see circle on the right of the figure) located in the holes around the rotational axis to a different location.
- Put on the control knob again.
Always pay attention to the correct position; the control knob can only be attached to the rotational axis in one orientation.
If you have limited the rotation range with the plastic pins, it may be necessary to rotate the rotational axis a little further by hand so that the control knob can be attached.
Do no use force when attaching the control knob!
Operation
- The room temperature controller can be switched on with the sliding switch (switch position "ON" = on, switch position "OFF" = off).
The room temperature controller can only function (and control the connected load), when it is switched on. - Use the control knob to set the desired temperature. The position with the snowflake symbol indicates the frost-protection temperature (+5^) , e.g., for a storage room.
- Depending on the temperature settings, the connected load is switched on or off.
Troubleshooting
The temperature set in the room temperature controller deviates from the actual room temperature (e.g., as measured with a thermometer)
- The heating power of your room radiator is insufficient (or the cooling power of your air conditioning is too low).
- The room temperature controller is influenced by external heat (e.g., by sunlight, proximity to heaters or electrical devices).
- The room temperature controller is installed next to a door or window where draught affects the room temperature.
- The room temperature controller is installed in a disadvantageous position, e.g., behind a curtain or on an exterior building wall.
The room temperature is not the same everywhere in the room.
Depending on the existing heating system (e.g., underfloor heating), air circulation, installation height and the wall temperature, considerable variations between the set position on the room temperature controller and the temperature measured with a thermometer.
Slow response of the room temperature to the temperature set on the room temperature controller
- In well-insulated buildings, it can take a long time for the room temperature to fall. On the other hand, it can take a long time for the temperature to rise in poorly insulated buildings and with cold exterior walls.
- Underfloor heating also reacts very slowly to the temperature setting on the room temperature controller.
Maintenance and cleaning
The product is maintenance-free. Repair or maintenance work must be carried out by a specialist.
You can use a clean, dry, soft cloth for cleaning. Dust can be removed very easily with a vacuum cleaner.
Do not use aggressive chemical or scouring cleaning agents, as this may lead to discoloration or changes in the material on the surface.
Disposal
The product must not be disposed of in the household waste!
We dispose of the product, when it is no longer of use, according to the
current statutory requirements.
