Troubleshooting
Emergency mode
Hot water for emergencies
If a fault occurs in the control system or in the components of the Compact P2, and the appliance stops as a result, it cannot produce domestic hot water.
If the installer cannot come right away or the malfunction occurs outside opening hours and so you cannot contact the installer, there is a possibility to get hot water by putting the appliance in emergency mode.
The emergency mode button is located behind the large door.
Emergency mode has three settings:
I - Auto: Additional electric heating is controlled by the appliance control system (default setting)
0 - Off: The supplementary electric heater is switched off and cannot be switched on via the appliance control system.
II - Manuel: The supplementary electric heater is switched on and cannot be switched off via the unit control system (do not switch on if there is no water in the tank).
In manual emergency mode, the water temperature can reach 75 °C, which can cause scalding, if you are not careful when switching on the hot water.
