What to do if the flue gas temperature sensor is shorted or measures a temperature above range on my REMEHA Boiler?
If your REMEHA Boiler's flue gas temperature sensor is either shorted or measures a temperature above range because the flue gas sensor is short-circuited, check the wiring and connectors for bad connections. Ensure the sensor is correctly fitted, and replace the sensor if it's faulty.
What causes the flow temperature to exceed the maximum operating value in a REMEHA Gas 220 Ace 220?
If the flow temperature of your REMEHA Boiler has exceeded the maximum operating value, it could be due to a flow temperature sensor above the normal range. Check the wiring and connectors for bad connections. Also, verify the circulation (direction, pump, valves), water pressure, and cleanliness of the heat exchanger.
What does it mean when my REMEHA Boiler displays a gas pressure switch error?
If your REMEHA Boiler displays a 'Gas Pressure Switch' issue, it's likely due to low gas pressure. Ensure the gas valve is fully opened, check the gas supply pressure, verify the GPS gas pressure switch is properly fitted, and replace the GPS switch if necessary.
How to fix a REMEHA Gas 220 Ace 220 when the flue gas temperature is too high?
If the flue gas temperature of your REMEHA Boiler has exceeded the maximum operating value, check the flue gas outlet system and the heat exchanger for clogs. If those are fine, the sensor may be faulty and require replacement.
What to do if REMEHA Gas 220 Ace 220 shows maximum difference between heat exchanger and flow temperature?
If your REMEHA Boiler shows 'Maximum difference between heat exchanger temperature and flow temperature', it indicates no flow or insufficient flow. Check the circulation (direction, pump, valves), water pressure, and heat exchanger cleanliness. Ensure the installation is properly vented and the sensors are operating correctly and fitted properly.
What to do if the flue gas temperature sensor is removed or measures a temperature below range on my REMEHA Boiler?
If your REMEHA Boiler's flue gas temperature sensor is either removed or measures a temperature below range due to an open circuit in the flue gas sensor, check the wiring and connectors for bad connections. Ensure the sensor is correctly fitted, and replace the sensor if it's faulty.
What to do if the heat exchanger temperature sensor is removed or measures a temperature below range on my REMEHA Gas 220 Ace 220?
If your REMEHA Boiler's heat exchanger temperature sensor is either removed or measures a temperature below range because the heat exchanger temperature sensor is open, check the wiring and connectors for bad connections. Ensure the sensor is correctly fitted and replace it if it's faulty.
What to do if the heat exchanger temperature sensor is shorted or measures a temperature above range on my REMEHA Boiler?
If your REMEHA Boiler's heat exchanger temperature sensor is either shorted or measures a temperature above range because the heat exchanger temperature sensor is short-circuited, check the wiring and connectors for bad connections. Ensure the sensor is correctly fitted and replace it if it's faulty.
Why is the ionization current below limit on my REMEHA Gas 220 Ace 220 Boiler?
If your REMEHA Boiler displays 'Measured ionisation current is below limit' due to no flame during operation, vent the gas supply to remove air, ensure the gas valve is fully opened, check the gas supply pressure, check the operation and setting of the gas valve unit, ensure the air supply inlet and flue gas outlet are not blocked, and verify there is no recirculation of flue gases.
How do I fix a configuration error on my REMEHA Gas 220 Ace 220?
If your REMEHA Boiler displays 'Configuration error or unknown configuration number', reset CN1 and CN2.
