Re: boiler doesn't respond to room thermostat

Aha, 5601 actuator head

it's not a spring return, it keeps driving round until it reaches the
desired position (depending on which of the three wires is live) and
then is switched off by a microswitch inside.

With the relay unplugged, there is no drive to positions - you can't
expect anything to work

I'll have a look tomorrow
