5 Maintaining the control unit
5.1 Replacing the battery
During a power failure, or if the mains power supply is cut off, the control unit switches to internal battery
power supply. The battery supplies the internal clock and internal memory of the microprocessor.
If the battery is empty, the control unit functions normally as long as the mains power supply is
connected. In the event of a power failure, the internal clock stops and the operating phase is not saved
in the memory. After the power supply has been restored, the clock is reset and the control unit remains
in the phase OFF (Stove mode) or "Fire up" (Boiler mode).
To replace the battery:
11. Disconnect the mains power supply.
12. The battery is located on the circuit board (see Abbildung 3). For this, the side shrouding must be
removed (see 13.1).
13. Take out the old battery out of its receptacle using INSULATED pliers or a similar tool. Ensure
that you do not bend the contacts of the battery receptacle.
14. Insert the new battery while observing that the correct polarity is maintained (see Abbildung 3).
15. Reconnect the mains power supply.
