What to do if a fault occurs

What to do if a fault occurs
The control unit has an advanced monitoring system that gives alarms if
anything unforeseen happens. Most alarms correct themselves. There is never a
risk of affecting something when you reset an alarm once or twice. In the event
of recurring alarms, contact your installer/service technician.
Example of an alarm:
When an alarm is triggered, an alarm window is displayed and a warning
signal sounds. The alarm window displays the alarm cause and the time and
date that the alarm occurred.
When you press the menu dial and Acknowledge is marked, the alarm
symbol disappears from the menu window and the alarm log, and the
warning signal is muted. The heat pump starts again within 15 minutes if
heating is required. If the fault has not been rectifi ed the lamp will remain
lit and the status LED will stop fl ashing red and will light red continuously.
Should several alarms have occurred on the heat pump, view the alarm log
where all alarms are listed. For active alarms, the alarm symbol is lit.

Emergency operation

On top of the electric box of the hot water distribution unit, there is a switch that
lights green during normal operation. If a fault occurs in the control unit and
heating production stops, emergency operation can be activated manually using
the switch, which then goes out. See the user guide for the Greensource Hot
water distribution unit.
The additional electric heater takes over the heating production during
emergency operation. Heating can therefore be obtained until the installer or
authorised service technician has remedied the fault.
This function must not be confused with Alarm mode, which means that the
compressor stops, for safety, due to an active alarm. Heating production is still
controlled by the control unit.
