Adjusting controller’s temperature reading
Use this function if the displayed room temper-
ature differs from the actual temperature.
Can be set between -3 and +3°C (0°C)

From speed 1 to speed 2 when heating
1-5, Off (1.5)
This is the difference between the temperature
setpoint and the room temperature where the
unit operating in the
AUTO
mode will switch
over to another speed. For speed 2 to speed 3,
the value of speed 1 to speed 2 must be added
to the value.

From speed 2 to speed 3 when heating
71
From speed 1 to speed 2 when cooling
71.5
From speed 2 to speed 3 when cooling
72
Time-based speeding-up, heating
0 = Off
1 = On (default)
If the temperature setpoint is not reached
within a specified period of time, the fan will
start rotating one speed higher. If the tempera-
ture is not reached within a specified period of
time, the fan will start rotating one speed lower
