It's the bottom valve. Only turns off when power is cut.
Programmer has heating switched off.

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...
