Information about the device
Device description
The radiothermostat with timer BN35 / BN35F allows for
automatic temperature control of heating devices and air
conditioners between 0°C and 70°C in increments of 1°C. For
this purpose, the socket thermostat is simply plugged in
between the heating device or air conditioner and the socket,
and the desired temperature is set at the radio transmitter. Via
its integrated sensors, the thermostat measures the current
room temperature and regulates the heating device or air
conditioner according to the desired nominal value.
Additionally, devices connected to the radiothermostat, such as
heating devices or air conditioners, can be automatically
controlled by a timer function. The timer function can be
programmed individually. Up to six different timers can be set
for each day.
One radio transmitter can be used to control up to 100socket
thermostats.

If the ambient temperature of the radio transmitter drops to 3°C
or below, the radio transmitter will automatically activate a frost
protection mode. The radio transmitter switches on and controls
the connected socket thermostat to 5°C or 7°C. FroS is
displayed on the segment display for settings(23).
Controlling several socket thermostats with one radio
transmitter only
You can control up to 100socket thermostats with only one
radio transmitter as long as they are within the radio range of
the radio transmitter (see Technical data).
Note
Please note that when several socket thermostats are
simultaneously controlled by one radio transmitter, all
socket thermostats which
- are active at that time
- have previously been connected to this radio
transmitter
- are within radio range
will adopt the current menu setting of the radio
transmitter!
1. Connect the radio transmitter to each individual socket
thermostat as described in the chapter Connecting the
radio transmitter and socket thermostat.
ðYou can now control the connected socket thermostats.
