What does it mean if the LED is constantly red on my Wolf Boiler?
If the LED on your Wolf Boiler is constantly red, it indicates that the ionization lead is shorted out or the ionization electrode is earthed (housing). Check the ionization lead and the position of the electrode to the burner, then press the reset button.
How to fix TBV excess temperature on Wolf CGB-K-24 Boiler?
If your Wolf Boiler shows a TBV excess temperature error, it means the flow temperature has exceeded the limit for TBV shutdown, possibly due to a severely contaminated heat exchanger. To resolve this, check the system pressure and heating circuit pump. Also, check the HC pump step switch, vent the heating system, and then press the reset button.
What to do if my Wolf Boiler shows TW excess temperature?
If your Wolf Boiler displays a TW excess temperature error, indicating that the flow/return temperature has exceeded the limit for TW shutdown, check the system pressure and vent the heating system. Additionally, set the pump to stage 2 or 3.
What to do if my Wolf CGB-K-24 gas fan doesn't stop?
If the gas fan in your Wolf Boiler does not stop, check the gas fan supply cable and the gas fan itself. After checking, press the reset button.
What causes TBA excess temp. in Wolf CGB-K-24 Boiler?
If your Wolf Boiler is showing TBA excess temp, it means that the flue gas temperature has exceeded the limit for TBA shutdown. Check for correct installation of the combustion chamber pot.
What to do if my Wolf CGB-K-24 shows Gas valve „2“ fault?
If your Wolf Boiler displays a Gas valve "2" fault, and a flame is recognised 15 seconds after burner operation, even if gas valve 2 has received a shutdown command, replace the gas combination valve.
What does Incorrect BCC mean on Wolf CGB-K-24 Boiler?
If your Wolf Boiler shows Incorrect BCC, it means that the boiler coding card is incompatible with the control unit PCB, so refit the correct parameter plug.
What to do if my Wolf CGB-K-24 shows Gas valve „1“ fault?
If your Wolf Boiler displays a Gas valve "1" fault, and a flame is recognized 15 seconds after burner operation even if gas valve 1 has received a shutdown command, replace the gas combination valve.
What to do if the flow sensor is faulty in my Wolf CGB-K-24?
If the flow sensor in your Wolf Boiler is faulty, meaning the flow temperature sensor or lead is faulty, check the lead and the flow sensor.
What to do if my Wolf CGB-K-24 has a fault in the 24 VAC supply?
If your Wolf Boiler indicates a fault in the 24 VAC supply, meaning the 24 V AC supply is outside the permissible range (e.g., short circuit), check the three-way valve and the gas fan.
