Control functions
The thermostat can regulate the tem-
perature in three different ways. This ena-
bles the comfort temperature and any
flooring temperature requirements to be
combined. How you select the function
you want is described in the section How
to set the thermostat/Control functions.
Floor thermostat – A sensor in the floor
measures the temperature and then
regulates the heating accordingly. If
the floor sensor is connected when the
thermostat is turned on for the first
time, this function is selected auto-
matically. Preset value is 22°C.
Room thermostat – The thermostat has
two built-in sensors for measuring the
room's temperature and controlling the
heating. The control function cannot
be selected when the floor sensor is
connected.
