Hi,
We have a 4 story 4 bedroom house with a C/H system originally installed in the late 80s. Since moving in I have replaced the boiler (with a Worcester Bosch 40 CDi conventional) and hot water tank, I have also placed wireless radiator control valves on most of the radiators.
Still left over from the original installation is the main thermostat for the central heating, it is an old Honeywell model (see picture). What I would like to do is to replace it with a wireless thermostat so that I can move the control unit into the basement which is the coldest part of the house and the one room which does not have control valves on the radiators.
What I need is some advice on what wireless thermostat would work with my existing wiring. I have attached a picture of the thermostat. There are three wires coming in (I have marked them on the image); line 1 is the live wire, line 3 switches on if the room is cold and off when it has reach desired temperature. Line 2 appears to be off all time time (at least when measured with my electricians screwdriver)
Any help or suggestions gratefully received!
Jasper.
