Hi, I have a baxi solo boiler WM60/4RS and a Landis & Gyr RWB252 timer but my Honeywell T6160 thermostat has nether been connected, can anybody shed light on the wiring connections please.


The color code for thermostat wiring is as follows.
The "R" terminal is power into the stat from the boiler control transformer. Normally 24 volts. The "Y" terminal is for cooling. Normally left blank for a boiler. The "W" terminal is for heat. This one used to start the heating cycle.The "G" terminal is for fan operation. Probably not used for a boiler. Check the boiler terminal board for these functions and write down the wire color on each one. Match the boiler colors to the right function on the stat. If you need more than this, let me know.

Operating worcester bosch 240 gas boiler


Control systems operate on a much lower voltage than the boiler. You should be able to put any kind of thermostat in for it. Just be sure of the wiring when doing it. If its a line voltage stat, I'll need more information to advise correctly.

I do not have a room thermostat connected to my oil fired central heating boiler. I want to install a wireless room thermostat to avoid having to run cable. how do i go about this and which is the best...


All wireless wall thermostats are Millivolt controlled. rather than having an 18 or 24 volt (transformer) wired wall thermostat. Before purchasing any wireless wall thermostat, you need to determine what your oil fired boiler requires for activation. My experience tells me, that it's going to require either 18 or 24 volts. In which case a wireless thermostat won't work.

Hope this helped you and thanks for choosing FixYa.

How do I wire a central heating room thermostat


You didn't mention if you had electric heat or gas heat. If you have electric heat you must move a wire on the thermostat to make the fan come on. Most all wall stats come ready for gas heat. No need to make a wire change for gas. Anyway I have a diagram of a typical central unit HERE

No central heating back boiler


back boiler run from a gas fire? check the instructions to operate the gas heat to the back boiler not just the fire
I presume that this a fully pumped system - air lock doubtful There maybe on/off valves on the pipes to and from the back boiler [situate close to cylinder] make sure they are on - anticlockwise turn
or there could be a blockage in the outlet from header tank usually in the loft. or If there is no water in it maybe the mains cold feed it is off.
Note if no water in it DO NOT USE the back boiler
