If the boiler has a 24 volt thermostat system, it may not be the thermostat that has failed. It may be the 24 volt inline transformer that's failed. To find out, you will need a circuit tester to make sure power is getting from the transformer to the thermostat. This way, you will know what needs to be replaced.

Correct signal does not seem to be sent from the controler to the boiler,either CH comes on or HW but not necessarily when they are supposed to. Boiler engineers have been out twice and both times advise...


we had one of these and found out the battery inside had failed. the battery is none replaceable. did try to replace it but it lost its memory and was only good as a switch. think when the battery fails it loses it memory and things start going wrong. so would say change it. now thinking on it should of changed the battery why having the old one on and taken the old one off after installing the new one.

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.

I have a honeywell cm927 control unit, and the red light on the receiver keeps flashing. i can manually turn the boiler on and off at the HC6ONG receiver. i've tried the faqs in the manual but to no joy....


The red flashing light means that there is an issues with the RF comms between control unit and receiver. You can reset by switching the boiler off and back on and then re-sending the temperature signal. You need to check batteries in you thermostat and also the position as the signal could be interfered with or it may be too far away from the receiver.

Need to wire a honeywell RTH7400D thermostat to 3 wire hot water


Just mark the old wires on the old thermnostat...R , W etc...and put them on the same terminals on the new 1.....also there should be some adjustment ire : switch on the back or under the cover to adjust for Hot water heating or electric heat...either is the setting you should have it on....also you shouldn't setback the thermostat at night or when away very much....2 degrees is fine , as the boiler will run along time to raise the temperature in the morning and may not get there by the set time

Chronotherm Three thermostat vs Buderus Logamatic Computer.


The outdoor thermostat senses the the temp of the outside air, and adjust the boiler water temp according to what it knows is best. The reason that the boiler is running longer is the old boiler used to be constantly sending 180ish degree water to the baseboard, now that water may only be 140ish degrees. The idea behind this is to reduce off cycle heat loss, as the greater the temp difference between the air temp and water temp, the quicker you loss heat. The theory in boiler run time is this, the less times it starts and stops, and the long run times will give you the best efficiency. Hope this answers you questions.
