If the maximum difference between the flow and return temperature is exceeded in your REMEHA Boiler, check the flow (direction, pump, valves). Also, check the water pressure, ensure the sensors are operating correctly and properly fitted, and verify the cleanliness of the heat exchanger.
What should I do if the difference between the flow and return temperatures is too great in my REMEHA Boiler?
If there is a difference between the flow and return temperatures that is too great in your REMEHA Boiler, replace the sensor if necessary and vent the central heating system. Check the flow (direction, pump, valves), the water pressure, and that the sensors are operating correctly and have been fitted properly. Check the cleanliness of the heat exchanger and that the heating pump is operating correctly. If present, check setting of boiler type parameter.
What causes a false flame signal in a REMEHA Quinta Pro Boiler and how can I fix it?
If a false flame signal occurs in your REMEHA Boiler, check the ionisation/ignition electrode. Inspect the gas valve, replacing it if necessary, and adjust the O₂/CO₂ settings.
What should I do if the phase and neutral of mains supply are mixed up in my REMEHA Boiler?
If the phase and neutral of the mains supply are mixed up in your REMEHA Boiler, invert the phase and neutral and set the parameter accordingly.
What does it mean when the blocking input is active on my REMEHA Quinta Pro Boiler and how do I resolve it?
If the blocking input is active on your REMEHA Boiler, remove the external cause, check the parameters, and inspect the wiring.
