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 con-
nected load), when it is switched on.
• Use the control knob to set the desired temperature. The position with the snow-
flake symbol indicates the frost-protection temperature (+5 °C), 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., be-
hind 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 tempera-
ture 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 insu-
lated 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 dis-
colouration or changes in the material on the surface.
Disposal
The product must not be disposed of in the household waste!
Please dispose of the product, when it is no longer of use, according to the
current statutory requirements.
