Not a very reliable system, transmitter keeps resetting to 17:25; locks up. Whole system then requires setting up from scratch. Had a replacement transmitter, no change, and same faults.
Perhaps this can help.

SOURCE: I have a Baxi Combi

You will need to isolate the boiler from the radiators because there is an auto feed valve that will continue to allow water into the system if the pressure in the boiler drops. There should be some valves off of the boiler that will allow you to do this.

SOURCE: Wiring Diagram for Ruud Heat Pump

Unfortunately, the wiring diagrams for heat pumps are not so easy to come up with. The outdoor unit will have its own diagram, but may not include the indoor air handler and will probably not include the thermostat. That said, the orange wire is commonly run from the thermostat to the reversing valve in the outdoor unit. This wire is usually not connected to the indoor airhandler. The orange wire is usually used in a unit that has the reversing valve energized in cool. Ruud, however has its reversing valve energized in heat. Probably not useful but maybe helpful

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.

Require room thermostat for ferroli combi boiler optimax 25c . I have a honeywell at the moment which stopped working. it has two wires coming into it from the boiler

Get a Ferroli wireless programmable room stat. City plumbing supplies can get hold of them but you'd be looking at approx £130. Part number 30800009. No wiring involved, the receiver connects to the boiler pcb. Had same problem but now fine.

I have a Honewell CM921/927 wireless programmable room thermostat that is operating the combi boiler in AUTO mode even when the time setting is meant to be off (no output). The target temp is 20 deg and...

If the room is at the set temperature even when the rad are warm the boiler is doing its job. It takes steel rads up to an hour to cool down so if they stay warm to the touch that is normal.It takes steel rads a long time to heat up when they get cold so its cheaper to let them not get real cold.I was told not to put a programmable thermostat on our boiler simply because it takes a lot of gas to bring your house up even two degrees. I run a non programmable and set our heat at 72 degrees and do not touch it all winter. There should be a water shut off on each rad so if you want your bedroom cooler just shut that shut off on that rad off.
