What should I do if the return temperature sensor is shorted or measures a high temperature on my REMEHA Quinta Ace 160?
- D
  Daniel CooperSep 6, 2025
  If the return temperature sensor is either shorted or measures a temperature above range in your REMEHA Boiler, it could be due to: * Return temperature sensor short-circuited: Bad connection: check the wiring and connectors. * Incorrectly fitted sensor: check that the sensor has been correctly fitted. * Faulty sensor: replace the sensor.

Why is the ionization current below the limit in my REMEHA Boiler?
- E
  Emily LewisAug 25, 2025
  If the measured ionization current is below the limit in your REMEHA Boiler, it could be due to several reasons: * No flame during operation: Vent the gas supply to remove air. * Gas valve issues: Ensure the gas valve is fully opened and check the gas supply pressure. * Air supply or flue gas blockage: Verify that the air supply inlet and flue gas outlet are not blocked. * Flue gas recirculation: Ensure there is no recirculation of flue gases.

Why has the flow temperature exceeded the maximum operating value in my REMEHA Quinta Ace 160 Boiler?
- J
  Jennifer HernandezAug 26, 2025
  If the flow temperature has exceeded the maximum operating value in your REMEHA Boiler, it could be due to: * A flow temperature sensor above normal range (high-limit thermostat): Check the wiring and connectors for bad connections. * No flow or insufficient flow: Check the circulation (direction, pump, valves), water pressure, and the cleanliness of the heat exchanger.

What causes the maximum temperature difference between the heat exchanger and flow in my REMEHA Quinta Ace 160?
- S
  Sherry DuncanSep 2, 2025
  If there's a maximum difference between the heat exchanger temperature and flow temperature in your REMEHA Boiler, it could be due to: * No flow or insufficient flow: Check the circulation (direction, pump, valves), water pressure, the cleanliness of the heat exchanger, and ensure the installation has been correctly vented to remove air. * Sensor error: Check that the sensors are operating correctly and that the sensor has been fitted properly.
