Hello,
I have had the same central heating in my house for years (it was here when I moved in). This has worked fine with no breakdowns at all so I am keen not to replace the boiler.
I want to try and get a thermostat to work with it though and this is where my confusion lies.
The set up is as below:
Potterton PrimaF combi boiler
Randall 102E programmable timer
Several radiators
The above all work fine and I can program the timer as I wish
Since moving in to the house however there has always been a thermostat in the hallway, this is a Honeywell T6060. My issue is I dont even know if this works. When turning the dial it clicks when turning off at around 15° and then clicks on at around 19°. However even when turned completely off (fully to the left) the heating still works normally. Under the cover there are 2 wires in the 2nd and 4th connection down (4 connections in total running top to bottom). The 1st and 3rd connection are empty. There is also an earth wire connected somewhere behind these connections.
My questions is firstly how can I tell if this is even wired back to my boiler?
Secondly if this is wired back to my boiler, can I simply replace it with a new thermostat and control the temperature in my house. It looks like a Honeywell CM907 may do the job from what I have read on various forums.
Any help would be appreciated.
