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.

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 am installing honywell thermostat rth111/rth221 old thermostat has two wires that are yellow and need to know where to hook up


First things first. What type of system? Heat only, boiler or furnace? Central cooling.
Do NOT take wires off the old thermostat yet, or mark the color wire, to the terminal letter. Most times W,Y,G,R, terminals and maybe even a C terminal.

Your new thermostat should have the same letters. Sometimes they mix up color wire with terminal letters...... example (yellow wire to w terminal)
Also turn off power to equipment it is controlling. It is not high volts but you can short out the transformer. Hook uo wire color to same letter terminal on old stat, to new stat. Thats it.

I have a Honeywell Thermostat CM67NG The flame symbol is showing on the thermostat, but there is no heat from radiators. The status code on boiler says there is ' no heat demand'. Boiler shows radiator...


You may have a broken thermostat wire. Disconnect the wires from the thermostat and please note what colors are hooked to which terminals. Cross the R and W wires and see if your heating system turns on. If it does not, you have a broken wire or bad connection at the heating system. If it does start, you have a bad thermostat or bad connection at the thermostat.

HONEYWELL CM921 ROOM THERMOSTAT


Remember the is a time and temperature controller if you want to use as an ON/OFF controller please ensure you OFF times are set to LOW temperatures for example at 8:00am I want the boiler firing to 21°C at 10:00 I want the boiler to go OFF at 5°C so ensure all so called OFF times are set to LOW temperatures.
