Remeha quinta 35C - hot water available but no heating

[Edric]

Hello and Merry Christmas. Sorry for posting in English, I am still learning Dutch (225 crowns on Duolingo and more than 20 videos watched on learndutch.org :).

My radiators at home are not heating up despite room temperature dropping to 17C while the set temperature is at 20C. I went to my CV ketel and saw code "6" - which according to the user manual means Aanvoertemperatuur > gewenste temperatuur + 5°C (= normale regelstop
tijdens c.v.-bedrijf).", which according to Google Translate means ""Flow temperature> desired temperature + 5 ° C (= normal control stop
during heating operation)."

What does this mean?

In the same panel, there is a button on "Branderschakelaar c.v.-bedrijf". When I pressed it, the red light came on - which means "c.v.-bedrijf uigeschakeld" / central heating operation switched off.

Does this indicate a fault on my indoor thermostat or is something wrong with the boiler?

Can someone please help?

Thank you in advance! :)

Code 6, the radiator supply temperaturen is 5 dec.c higher than set in the system parameters.

This situation occurs when there is insufficient flow trough the central heating system eg. Radiators.

Check the valves on de radiators they must be openen.

Second, there is al valves in your boiler that switchen between hotwater and radiators.
If the motor of valve is faulty the valves wil remain in hotwater position and the boiler cant het the Heat ro the radiators:code 6.

Fijne avond.
