Auto restart
When power returns after a power supply failure, the auto restart function
reapplies the user interface settings at the time of the power failure. Therefore, it
is recommended to always enable the function.
User settings > Electricity price >
Low
User settings > Gas price
If electricity and gas prices are not known, the PE
factor (primary energy factor) is used for the
calculation instead. Lower values of the PE factor
result in increased use of the heat pump. Higher
values of the PE factor result in increased use of
the auxiliary boiler.
▪ 0: Very high
▪ 1: High
▪ 2: Medium
▪ 3: Low
▪ 4: Very low
Alarm output: Indicates the logic of the alarm
output during malfunctioning.
▪ 0 Abnormal: The alarm output will be
powered when an alarm occurs. By setting this
value, a distinction is made between the
detection of an alarm, and the detection of a
power failure.
▪ 1 Normal: The alarm output will NOT be
powered when an alarm occurs.
