Hey guys,


I'm trying to create a timed circuit that will replaced the broken timer on this boiler - see image.


The timer will dictate when the middle knob will be turned from it's current position (off) to where the 50 mark is.


My initial idea was to use a 12v relay, timer and some kind of motor/actuator to physically move the knob (this is the only way to turn the radiators on and off). I can attach something to the knob that can be driven via motor or actuator.


I'm struggling to something to move the knob. I've looked at linear actuators but it seems overkill for the use-case.


Any ideas?
