Floor controlling:
■
– The thermostat controls the floor temperature.
– For the application "Floor controlling" a floor sensor must be
connected.
– If there is no floor sensor connected, there will be
displayed the note "Sensor floor error".
Room controlling:
■
– The thermostat controls the room temperature on the basis of
the internal sensor (air temperature).
Room controlling / floor limitation:
■
– The thermostat controls the room temperature on the basis of
the internal sensor and also monitors the floor temperature to
adjust the control depending on extreme floor temperature
values.
– The user sets the minimum and maximum temperature limit
for the floor. The maximum limit is set to protect wooden floors
from being destroyed due to excess temperatures. So even if
the internal sensor requests more heat, the thermostat won't
switch on. The minimum temperature keeps the floor warm
when there are other heat sources in the room e.g. a fire
place. So even if the internal sensors measures a sufficiently
warm room, the thermostat will control the floor temperature to
be on a certain minimum level.
– For the application "Room controlling / floor limitation" a floor
sensor must be connected.
– If there is no floor sensor connected, there will be
displayed the note "Sensor floor error".
YES / NO
Yes:
■
– If the Thermostat is in mode OFF, the temperature set value is
+5°C.
No:
■
– If the Thermostat is in mode OFF, no set value is active at all.
