[OpenTRV-dev] Radiator debugging and re-calibration

[Bruno Girin]

Full marks to Bo, that's exactly what it was: the pin that controls the
valve was stuck in the closed position.

One point to note thought that may be useful to identify problems in a
system: the way it manifested itself at the system level (i.e. group of
radiators + boiler control) was that one of the valves was constantly
asking for heat because the room never got warm. Could that be considered
an alarm condition that should prompt the user to check whether the
radiator is working properly?

Cheers,

Bruno
