What should I do if the return temperature sensor is shorted or reads too high on my REMEHA Quinta Ace 65 Boiler?
If the return temperature sensor is either shorted or measures a temperature above range in your REMEHA Boiler, you should check the wiring and connectors, ensure that the sensor has been correctly fitted, and replace the sensor if necessary.
Why is the return temperature sensor not detected in my REMEHA Boiler?
If the return temperature sensor was expected but not detected on your REMEHA Boiler, check the wiring and connectors. Also, consider replacing the sensor.
What to do if The reserved space in memory for custom parameters value is full in REMEHA Quinta Ace 65 Boiler?
If the reserved space in memory for custom parameters value is full on your REMEHA Boiler, and no more user changes are possible, reset CN1 and CN2. If the problem persists, replace the CSU or the CU-GH.
What causes maximum heat exchanger temperature increase exceeded in REMEHA Boiler?
If the maximum heat exchanger temperature increase has been exceeded in your REMEHA Boiler, check the circulation (direction, pump, valves) and the water pressure. Also, check the cleanliness of the heat exchanger. Ensure that the sensors are operating correctly and that the sensor has been fitted properly.
What to do if return temperature sensor is either shorted or measures a temperature above range in REMEHA Quinta Ace 65 Boiler?
If the return temperature sensor is either shorted or measures a temperature above range on your REMEHA Boiler, check the wiring and connectors if the return temperature sensor is short-circuited. Also, check that the sensor has been correctly fitted if it was incorrectly fitted and replace the sensor if it's faulty.
What causes the maximum difference between flow and return temperature in REMEHA Boiler?
If there is a maximum difference between the flow and return temperature in your REMEHA Boiler, you can: * Check the flow (direction, pump, valves). * Check the water pressure. * Check the cleanliness of the heat exchanger. * Check that the sensors are operating correctly and that the sensor has been fitted properly.
How to resolve flue gas temperature exceeding maximum value in REMEHA Quinta Ace 65 Boiler?
If the flue gas temperature has exceeded the maximum operating value in your REMEHA Boiler, you should: * Check the flue gas outlet system. * Check the heat exchanger to ensure that the flue gas side is not clogged. * Replace the sensor.
What causes a low ionization current in my REMEHA Quinta Ace 65?
If the measured ionization current is below the limit in your REMEHA Boiler, consider the following: * No flame during operation: Vent the gas supply to remove air. * Gas valve issues: Check that the gas valve is fully opened, and check the operation and setting of the gas valve unit. * Gas supply pressure: Check the gas supply pressure. * Blockages: Check that the air supply inlet and flue gas outlet are not blocked. * Flue gas recirculation: Check that there is no recirculation of flue gases.
Why does my REMEHA Boiler show a 5x Error of unintended Flame Loss occurrence?
If your REMEHA Boiler shows a 5x Error of unintended Flame Loss occurrence, it could be due to: * Low ionization current: Vent the gas supply to remove air. * Gas valve issues: Ensure the gas valve is fully opened and check its operation and setting. * Gas supply problems: Check the gas supply pressure. * Blockages: Verify that the air supply inlet and flue gas outlet are not blocked. * Flue gas recirculation: Ensure there is no recirculation of flue gases.
What to do if the Return temperature difference is too large in REMEHA Boiler?
A large return temperature difference in your REMEHA Boiler can be caused by: * Air in the central heating system: Vent the system to remove air. * Water pressure issues: Check the water pressure. * Incorrect boiler type parameter setting: Verify the setting. * Circulation problems: Check the direction, pump, and valves. * Heating pump malfunction: Ensure the pump is operating correctly. * Heat exchanger cleanliness: Inspect and clean the heat exchanger if necessary. * Sensor issues: Check the operation and fitting of the sensors. Replace the sensor if necessary.
