For last couple of weeks heating/radiators havent been turning off.
Checked, and it seems one of the motorised valve actuators (Honeywell) is alway open. (No resistance on the little lever) The metal casing is very hot compared to the other 2 so an wondering if the motor is running constantly?
The only time it closes is if I kill the power to it completely. When power is off the resistance returns to the little lever) As soon as it's powered on again it opens...
Is this likely to be the actuator at fault (if so I'll just replace it) or is it likely that something else could be causing the motor to be constantly on?
