External alarm output (relay)
An alarm can be connected via the external relay
connection; a sound signal, lamp or the like that
warns if the heat pump is in alarmed position.
The alarm relay has a changing function.
When the alarm is not active (no alarm), NC-COM
is closed and NO-COM is broken.
Here you choose which function is best suited for
the external alarm you want to use.
