Warning Frost protection alarm
The frost monitoring system has detected an
insufficient water temperature below the
frost protection limit.
The heat pump is at risk to be damaged by
frost.
Primarily, look at the
other alarms. These are

standstill of the system. A
rectification of those
should also cancel the
frost protection alarm.
