What to do if Weishaupt W-FM 25 Control Unit shows excess voltage?
If the Weishaupt Control Unit indicates excess voltage, you should interrupt the voltage supply temporarily. Also, check the voltage supply and reset the burner. If the fault reoccurs, replace the combustion manager.
Why does my Weishaupt W-FM 25 show low voltage?
If the Weishaupt Control Unit indicates low voltage, the cause is low voltage. You should check the voltage supply.
What to do if the display flashes on Weishaupt W-FM 25?

What causes an internal unit fault in Weishaupt Control Unit?
If the Weishaupt Control Unit indicates an internal unit fault, the cause is an internal unit fault. To resolve this, interrupt the voltage supply temporarily. If the fault reoccurs, reset the burner and replace the combustion manager.
What to do if Weishaupt W-FM 25 shows ambient temperature too high?
If the Weishaupt Control Unit indicates that the ambient temperature is too high, the cause is high ambient temperature. You should interrupt the voltage supply temporarily and check the ambient temperature. If the fault reoccurs after resetting the burner, replace the combustion manager.
How to troubleshoot insufficient gas pressure on Weishaupt W-FM 25 Control Unit?
