MANAGE ALARM
In the event of an alarm, some type
of malfunction has occurred, which is
indicated by the status lamp shining
with a steady red light. A dialogue box
appears in the display, containing in-
formation about the alarm.
ALARM
In the event of an alarm with a red
status lamp, a malfunction has oc-
curred. The display shows what type
of alarm it is and lets you reset the
alarm.
In many cases, it is sufficient to se-
lect "Reset alarm" for the installation
to revert to normal operation.
If the red lamp goes out after select-
ing "Reset alarm", the alarm has been remedied.
It the red light is still on or if the alarm recurs, the cause
of the problem remains.
"Auxiliary operation" is a type of emergency mode. This
means that the installation attempts to produce heat
and/or hot water, even though there is some kind of
problem. This could mean that the heat pump's com-
pressor is not in operation. In this case, any electric ad-
ditional heat produces heat and/or hot water.
Caution
To select "Auxiliary operation", an alarm action
must be selected in menu 7.1.8.1 – "Alarms"
in the main product.
Caution
Selecting "Auxiliary operation" is not the same
as correcting the problem that caused the
alarm. The status lamp will therefore remain
red.
