mode
Meaning
(OFF)
The installation is fully switched off. This mode is also used to acknowledge and reset
alarms.
AUTO
The heat pump automatically controls the compressor operation and auxiliary heater (if in-
stalled and activated in the system).
COMPRESSOR
The control system is controlled so that only the outdoor unit (compressor) is allowed to
operate. In this operating mode there won't be any auxiliary heating backup, if there's a
need for it and also peak heating charging (anti-legionella function) of the hot water will
not run because the auxiliary heater is not used.
AUX. HEATER
The control system only permits the auxiliary heater to be in operation (if installed and acti-
vated in the system).
HOT WATER
In this mode the heat pump only produces hot water. No heat is supplied for space heat-
ing.
Warning
If any operation mode other than AUTO or
AUX. HEATER is to be used during the winter
season, the water in the heating system must
be drained. Otherwise any alarms triggered
that will cause the outdoor unit to stop might
lead to freezing damage to the system.
