WARNING
Material damage from frost!
The auxiliary heater may be irreparably damaged by frost.
▶ Do not start the indoor unit if there is a possibility of the heating or
auxiliary heater being frozen.
HThe system will be damaged if it is commissioned without water
▶ Only operate the device when it is filled with water and at the correct
operating pressure.
Do not turn on the indoor unit in case that existing valves to the heating
system or to the heat pump are closed.
▶ Check that all valves in the system are opened.
When powering up the device, a dry-run check is performed to check if it
is filled with water. To avoid false alarms, at least one heating zone must
be open when powering on the appliance. The compressor and electric
heater is blocked during the dry-run check. The duration of the check is
2 minutes.
▶ Check if the valves to, at least, one heating zone are open before
powering on the appliance.
If the power of the electrical heater is restricted by settings or installation
(i.e. 1-phase only), certain features of this appliance might be limited.
This applies to, for example, the Thermal disinfection feature. To avoid
limitations for this feature specifically, the duration of this operation can
be increased in the Maximum time setting (in the Thermal disinfection
menu). Similar solutions might be available for other features ( see
HMI documentation).
Before you turn on the appliance please check that all external
connected devices are well earth connected.
