Checking operation
During normal operation, the alarm indicator lights green continuously
to show that everything is OK. When the alarm is triggered, it flashes
green at the same time as a text message is shown in the display.
Regularly check the alarm indicator to
ensure that the installation is working
correctly. In event of alarm the heat
pump will if possible supply heating
to the house, primarily with the com-
pressor, secondarily with the auxiliary
heater. Hot water will stop to indicate
that something noteworthy has occur-
red.
In event of alarm this is indicated in the display with the text ALARM and
an alarm message. The potential alarm messages are:
