Sensor: How to specify whether an external floor sen-
sor, the built-in room sensor or both is used to control
the floor heating
1. Turn the button to choose one of the following sensor
settings:
If both a room sensor and a floor sensor is
used, choose rFS.
This option is suitable for all rooms but
wet rooms. The thermostat must be in-
stalled in the same room as the floor sen-
sor and the heating elements.
If only a floor sensor is used, choose FS.
The built-in room sensor is not used. This
option is suitable for rooms in which a
constant floor temperature is required,
e.g. in a bathroom.
If only a room sensor is used, choose r S.
This option is not recommendable due
to an increased risk of overheating the
floor. The thermostat must be installed in
the same room as the heating elements.
2. Press the button once to confirm your selection.
