Try adjusting the gas to air mixture and flow rate. I don't work well in very cold weather, either. I think that's fairly typical. Even a diesel engine is difficult to start in cold cold weather. Perhaps heating the room where the boiler is would help or at lest insulate the room well. Including stopping any drafts that may be causing a windy condition in or around the combustion chamber.

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.

High pressure


1)If its going into the red,it will more than likely be
relieved in the automatic relief valve, which you really dont want to happen.

2) You must have a vent somewhere on the system
that either autmotically relieves pressure or you have
to manually relive pressure.

3) Look for a autovent. Which is round and usually
installed somewhere at the highest point of the system. If you have one,there is a little round cap
on top of it, screw it tight and then lossen it until
you have air coning out.

4) it sounds like you have air in the system and you
need to get it out.. If you can turn the boiler off
but keep the pump running , either way you have
to get the air out of the system

Hi There, I have an Ideal Response 120 Combi Boiler. Each day the water pressure falls to 0 on the pressure gauge. In order to get hot water and Cental Heating I increase the pressure to 1.5. The Hot water...


I have the same boiler with a similar issue. The water is more than likley leaving the system from the pressure relief valve, which will be routed outside. It sounds like you have lost the pressure in your expansion tank, which is inside the boiler. With the boiler pressure at zero and the power isolated, the expansion tank can be accessed from a panel at the top of the boiler on the right hand side. You will see a valve on the red expansion vessel like the one on a car tyre and can be pressurised with a car tyre air pump. I think from the manual the pressure should be about 1 bar, but it depends on the length of pipework on your system. A competent boiler engineer should be able to sort this out, but it may be that your valve is leaking, or the expansion vessel has failed and the problem will occur again.
