Hi. Just moved into a house with a Baxi 105e boiler controlled by a Honeywell hcw80 thermostat. The heating was ok until the house got rewired but since then the c/h will not come on. The hot water works ok and the pressure is just over 1 bar. I have reconnected the two honeywell devices and they do appear to be communicating. However when i move the dial for the stat the heating does not kick in. When i turn the dial to 25 degrees a red light comes on and goes off after a few seconds. Does this sound like a stat problem or a rewire problem? Thanks in advance!

Does the green light come on on the receiver?
When you press the receiver's override button does the boiler fire?

Yes Dan the green light comes on and have also changed the batteries.

Sorry...no the boiler does not fire.
Then something has happened to the relay - or the wiring to the boiler.
The batteries had already worked with the unit but no i have not replaced them with duracells. Will try that also...ta
Try bridging terminals 1 & 2 on the boiler's incoming terminal.
Does it fire then?
I assume you have the left hand knob set to the tap and radiators icons?

On transmit the unit takes a high peak current which the cheap carbon zinc batteries sold at 10 for a £1 in the 99p store cannot supply.
Only alkaline batteries give higher currents and they are more expensive and Duracell are the only ones to be trusted.

Lol bit of a novice Dan,ill end up blowing half a newcastle up man!
I could post something witty here, but I'll restrain myself.
If i wanted to remove the stat, obviously i turn the main switch off, then remove the wires from the stat into the terminal block inside the boiler. What about the wires coming from the other side of the block...do these need to be removed also?
