4. Alarm handling

There are three different alarm levels; information
alarms, heat pump circuit alarm and system alarm.
Three different alarms can be stored at the same time.
Each alarm must be reset by pressing the control button
at the control panel.
The information alarms do not stop the heat pump, but
informs the user that there is a disturbance that has to
be solved as soon as possible (Alarm no: 8, 9 and 10).
The heat pump circuit alarms stop the hot water
production with the compressor and switches to
100 % supplementary heating sources (immersion
heater or external boiler). (Alarm No: 3, 4, 5 and 6).
System alarms blocks the whole product. (Alarm no: 1
and 2).
The alarms are presented in the alarm menu, where
also the alarms are confirmed. Each alarm must be
confirmed before normal operation is possible. If no
action is taken before an alarm is confirmed the alarm
will still be on. In the case several simultaneous alarms,
they are placed in a row. The alarms will be presented in
order of importance.
