Troubleshooting
Emergency mode
Emergency mode, domestic hot water
If the unit stops as a result of an error in the control system or in one or more components, it will not be
able to produce domestic hot water.
If the installer is not available immediately, you will be able to get domestic hot water by setting the
unit to emergency mode.
The button for emergency mode is located behind the large door
There are three emergency mode settings:
I - Auto: The control system of the unit controls the supplementary
electric heating (standard setting)
0 - Off: The supplementary electric heating is off and cannot be
turned on via the control system of the unit
II - Manual: The supplementary electric heating is turned on and
cannot be turned off via the control system of the unit (Do not turn it
on if there is no water in the tank)
CAUTION
During manual operation the water temperature can reach 75 °C. This can cause scalding if you
are not careful when you turn on the hot water.
