Description
Sets the zone 1 heating setpoint when
"Holiday mode" is active
If the parameter "Zone 1 CH setpoint" is set to
a lower value than the parameter "Zone 1 CH
holiday setpoint", the latter will assume the
same value as set on the parameter "Holiday
mode" (this happens when storing).
Sets the zone 2 heating setpoint when
"Holiday mode" is active
If the parameter "Zone 2 CH setpoint" is set to
a lower value than the parameter "Zone 2 CH
holiday setpoint", the latter will assume the
same value as set on the parameter "Holiday
mode" (this happens when storing).
When selected, a new screen will open to
sequentially set the start and end date of
"Holiday mode".
This function is an alternative to the
parameter "Manual holiday mode".
Allows the manual activation of "Holiday
mode", which remains active until manually
deactivated.
When set to 'ON', this parameter has priority
over the previous parameter 'Set holiday
period'.
This function is an alternative to the
parameter "Set holiday period".
