What to do if flow temperature sensor has open circuit in REMEHA Quinta Pro 90?
If the flow temperature sensor has an open circuit in your REMEHA Boiler, check the wiring for bad connections. Also, check that the sensors are operating correctly and that the sensor has been correctly fitted. Replace the sensor if necessary.
How to troubleshoot return temperature sensor open circuit in REMEHA Boiler?
If the return temperature sensor has an open circuit in your REMEHA Boiler, check the wiring for bad connections. Also, check that the sensors are operating correctly and that the sensor has been correctly fitted.
Why does REMEHA Boiler have maximum difference between the flow and return temperature exceeded?
If the maximum difference between the flow and return temperature is exceeded in your REMEHA boiler, it could be due to no flow or insufficient flow, or a sensor error. Check the flow (direction, pump, valves), the water pressure, that the sensors are operating correctly, that the sensor has been fitted properly, and the cleanliness of the heat exchanger.
How to fix REMEHA Boiler maximum flow temperature exceeded?
If the maximum flow temperature is exceeded in your REMEHA boiler, it could be due to no flow or insufficient flow. Check the flow (direction, pump, valves) and reasons for the heat demand.
What to do if the water pressure is too low in my REMEHA Quinta Pro 90?
If the water pressure is too low in your REMEHA Boiler, you should check the water pressure. Also, fill the boiler and the installation with water.
What to do if REMEHA Quinta Pro 90 gas pressure is too low?
If the gas pressure is too low in your REMEHA boiler, it might be due to insufficient flow or an incorrect setting on the gas pressure switch (Gps) on the SCU PCB. Check that the gas valve is fully opened, check the gas supply pressure, check whether the Gps has been correctly fitted, and replace the Gps switch if necessary.
What causes REMEHA Boiler to have five failed burner starts?
Five failed burner starts in your REMEHA boiler can be caused by no ignition spark. To solve this, check the cabling of the ignition transformer, the ionization/ignition electrode, breakdown to earth, the condition of the burner cover, the earthing, or a defective control SU PCB.
What to do if REMEHA Boiler flow temperature sensor is short circuited?
If the flow temperature sensor is short-circuited in your REMEHA boiler, it may be due to a bad connection or the sensor not being connected properly. Check that the sensor has been fitted properly, ensure the sensors are operating correctly, and replace the sensor if necessary.
Why does REMEHA Quinta Pro 90 Boiler have maximum increase of the flow temperature exceeded?
If the maximum increase of the flow temperature has been exceeded in your REMEHA boiler, it could be due to no flow or insufficient flow, or a sensor error. Check the flow (direction, pump, valves), the water pressure, that the sensors are operating correctly, that the sensor has been fitted properly, and the cleanliness of the heat exchanger.
What causes REMEHA Quinta Pro 90 Boiler temperature of heat exchanger to be too high?
If the temperature of the heat exchanger in your REMEHA boiler is too high, it could be due to a bad connection, the sensor not being connected correctly, or no circulation. Check that the sensors are operating correctly, that the sensor has been fitted properly. If necessary, replace the sensor. Vent the air from the CH system, check the circulation (direction, pump, valves), the water pressure and the cleanliness of the heat exchanger. Also, if present, check the boiler type parameter setting.
