How do i connect a standard room stat to my combi boiler


Honeywell stats, esp the rounds ones, have multiple wiring diagrams that come with them including those for radiant which is a boiler hookup.
The stat has to go through the zone controller as your combi has a P1 zone priority set for the water heater and other P2-P? zones for heating loops. TACO will help you with this but it'd be really cool not to be so cheap you don't call a Tech for a Service Call to do a professional's job.

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.
