If your Wolf Boiler displays a fault with the DHW outlet temperature sensor, caused by a faulty or disconnected lead or sensor, check the lead and replace the sensor if required.
What to do if my Wolf Boiler shows TW excess temperature?
If your Wolf Boiler displays a TW excess temperature warning, the flow/return temperature has exceeded the limit. You should check the system pressure and vent the system. Also, make sure to set the pump to stage 2 or 3.
Why is my Wolf CGG-1K-24 not establishing a flame?
If your Wolf Boiler fails to establish a flame during burner start, the issue could stem from the gas supply. Check the gas supply pipe and open the gas tap if it's closed. Also, inspect the ignition electrode and ignition cable. After these checks, press the reset button.
What does it mean if my Wolf CGG-1K-24 Boiler shows flow monitoring?
If your Wolf Boiler indicates flow monitoring, it means there's an excessive temperature change (flow temperature 2, flow temperature 1 > 12 K). To resolve this, vent the heating system, check the system pressure, and inspect the heating circuit pump.
What to do if my Wolf Boiler gives a false flame signal?
If your Wolf Boiler is giving a false flame signal, meaning a flame is recognized before the burner starts, press the reset button.
What to do if there is a fault sensor throughput in Wolf Boiler?
If your Wolf Boiler indicates a fault with the sensor throughput, caused by a faulty or disconnected lead or sensor, check the lead and replace the sensor if required.
How do I fix a faulty flow sensor in my Wolf Boiler?
If your Wolf Boiler indicates a faulty flow sensor, where the sensor for the flow temperature or the lead are faulty, check the lead and the flow sensor.
How to fix a faulty outside temperature sensor on Wolf Boiler?
If your Wolf Boiler displays a faulty outside temperature sensor, where the sensor or the lead is faulty, check the lead and the outside temperature sensor.
What to do if no flame is established in my Wolf Boiler?
If no flame is established during burner start in your Wolf Boiler, check the gas supply pipe and open the gas tap if needed. Also, inspect the ignition electrode and ignition cable. If the issue persists, press the reset button.
What to do if my Wolf CGG-1K-24 Boiler reports fault sensor DHW outlet temperature?
If your Wolf Boiler indicates a fault with the DHW (Domestic Hot Water) outlet temperature sensor, meaning the lead or sensor is faulty or not connected, check the lead and replace the sensor if required.
Observe all national safety regulations and installation requirements.
Commissioning must only be carried out by the system installer or a commissioning engineer designated by him.
The system installer must hand the operating instructions to the system user and instruct him/her in the operation of the system.
