Heating not going off even though I’ve turned it off at the thermostat and controls??

The Danfoss FP715 Si heating may not be turning off despite being switched off at the thermostat and controls due to the following possible reasons:

1. Cylinder Thermostat Detection: If the hot water cylinder thermostat detects that the water temperature has not yet reached the set level, the heating system may continue to operate.

2. Programmed Mode: The programmer may be set to "ON" or "ALLDAY" mode, which keeps the heating running continuously. Ensure it is set to "AUTO" or "OFF" if you want it to turn off.

3. Temporary Override: The +1HR override button may have been pressed, causing the heating to stay on for an extra hour.

4. Service Interval Timer: If the property owner (e.g., a landlord) has enabled a service interval timer, it may affect the heating operation.

Check the programmer settings, override functions, and thermostat to confirm the correct configuration.
