Attention
Par.
AL35
anti-freeze alarm delay (low outlet air temperature air/air unit) when the unit starts in heat pump
mode.
In stand-by or remote OFF: there is an anti-freeze alarm and the time delay in AL35>0, if the unit is manually
turned on in heat pump from keyboard or remote input, the alarm is reset so the unit can start at least for the
time set in AL35 in order to heat the water or the air. After the AL35 delay if the anti-freeze probe is still lower
than AL33 setpoint for AL36 seconds the unit is locked again with an anti-freeze alarm.
