I am totally new to this forum. But I am hoping that I will surely get an answer to my questions. I just bought the house and it has
Potterton Boiler system
Switchmaster 805 control
Teddington thermostate
Boiler system works manually and via thermostat but dialer on the 805 does not rotate automatically. So to start, I had to manually turn the knob on the boiler. Keeping thermostat to 0, I can get hot water. Keeping thermostat to desired temp, turning the knob ON gives hot water and CH. As winter is on its way, I have to fix this issue.I am looking at various forums and it shows the replacement side but I am not sure if my Switchmaster 805 is faulty or wiring is faulty? I am willing to buy new timer if I can confirm that it will work. So couple of questions,
How do I confirm that my Switchmaster 805 works?
What is the function of the Randall box underneath switchmaster 805?
Will replacement of compatible Switchmaster work in this condition?
