Further warnings:
The construction of the product corresponds to the protection-class II (double or re-
inforced isolation). Ensure that the insulation of the housing is neither damaged nor
destroyed.
Before installing the switching module, disconnect all poles from the mains voltage
using a residual current device (RCD). There must be an appropriately rated fuse or
circuit breaker between the RCD and the product.
The device must be de-energised during installation and connection of the switching
module. Furthermore, turn off the automatic circuit breaker and the RCD to disconnect
all poles from the mains voltage. Secure it against unauthorised reconnection, e.g.
with a warning sign. Then check to ensure there is no voltage with a suitable measu-
ring device (e.g. a two-pole voltage tester).
Never connect the product to the power supply immediately after it has been transfer-
red from a cold room into a warm one (e.g., during transport). The condensation that
forms may destroy the device. Moreover, there is danger of electric shock!
Always let the product reach room temperature rst. Wait until the condensation has
evaporated. In some cases, this may take several hours. Only once the condensation
has evaporated should it be installed, connected to the power supply and put into use.
Do not use the product in rooms with adverse environmental conditions, where com-
bustible gases, vapours or dust are or may be present! This may cause an explosion!

Operating instructions
Wireless heating thermostat
Item no. 2735095
1 Intended use
This product is a wireless heating thermostat intended for temperature control and can be
integrated into an electric heating system, such as oor heating or panel radiators.
You can schedule the room temperature precisely to the hour to suit your individual needs.
You can programme the room temperature for 7 days in advance. With six programmable time
settings a day, you can reduce your heating costs and adjust the temperature in your home to
your needs. You can save on heating costs when you are on holiday or away on business. The
holiday mode keeps the temperature in your home constant at a preset level.
The wireless heating thermostat is powered by two Mignon batteries (AA). The switching re-
ceiver is connected directly to the mains voltage. You can also connect a consumer operated
via the mains voltage supply to the switching receiver and switch it on or off through tempera-
ture control.
The heating thermostat has a built-in temperature sensor (probe) and allows connecting an
external sensor to the switching module. The product has a button lock feature that prevents
incorrect operation and a permanently installed decoupling capacitor for data backup in the
event of a power failure. This device has an IP20 ingress protection rating and is suitable for
dry rooms and indoor use. Do not use it outdoors. Contact with moisture, e.g. in bathrooms,
must be avoided under all circumstances.
For safety and approval purposes, do not rebuild and/or modify this product. If you use the
product for purposes other than those described above, the product may be damaged. In addi-
tion, improper use can result in short circuits, res, electric shocks or other hazards. Read the
instructions carefully and store them in a safe place. Make this product available to third parties
only together with its operating instructions.

10 Range
The transmission range of the radio signals between the temperature controller and a suitable
radio receiver is up to 200 m under optimal conditions.
However, this indication refers to the so-called “open eld range” (with direct visual con-
tact between transmitter and receiver without interference).
Different objects have a different impact on the range; therefore, no specic range can be
guaranteed. The range should be sufcient for use in a detached house.
Sometimes the range can be considerably reduced due to:
Walls, reinforced concrete ceilings and metal-framed drywalls.
Coated/metallised insulated glass.
Proximity to metal and conductive objects (e.g. radiators).
Proximity to the human body.
Other devices using the same frequency for communication (e.g. wireless headphones,
wireless speakers).
Proximity to electric motors/appliances, transformers, power supplies, and computers.
11 Care and cleaning
This product does not require maintenance.
Use a dry, soft, lint-free cloth to wipe the panel. Do not use aggressive cleaning agents, as
these can cause discolouration.
Always activate the button lock before wiping the front panel. Accidentally pressing the
buttons can cause unintended settings.
