Oppositely, changeover from cooling to heating will occur when the room
temperature drops below the minimum of the desired heating temperature
subtracted by the hysteresis value (thus 22–1=21°C) and the desired cooling
temperature subtracted by the offset value (thus 24–4=20°C)
Guard timer to prevent too frequent changing from heating to cooling and vice
versa.
# Code

Description
Hysteresis: ensures that changeover is only done
when necessary.
The space operation only changes from heating
to cooling when the room temperature rises
above the desired cooling temperature added by
the hysteresis value.
▪ Range: 1°C~10°C
Offset: ensures that the active desired room
temperature is always reached.
In heating mode, the space operation only
changes when the room temperature rises above
the desired heating temperature added by the
offset value.
▪ Range: 1°C~10°C
Description
▪ 0: Single zone
Only one leaving water temperature zone:
a Main LWT zone
