Can't find Honeywell CM927 rf Receiver on Logic Combiner's 30!?

[karlchop]

Hi all,

The screen has gone on my CM927 thermostat and I either want to replace it or get something cheaper from another brand. I've tried fixing it with heat but no joy.

Problem is I can't find the rf receiver to confirm which model it is so I can buy a new thermostat!

Is there a chance it's actually installed in the boiler casing somewhere?

Boiler is in kitchen, no sign of this receiver anywhere!

Thanks,
Karl

Receiver mustt surely be near boiler, just follow cable from boiler.
Wolseley do a straight swap for that model, no need to change back box.
Approx £60

Sort of if you have an Intergas, these will link directly to the boiler.

There aren't any cables coming out from the boiler at all, nothing on the wall anywhere. The only thing I can think is that it's in the cupboard above the boiler as the boiler is built in to a kitchen unit.

Would you know the model of the Wolseley one?

The front cover doesn’t look like it’ll come off without taking the cabinets apart

Some wiring coming out of the bottom, lower right as you look at it, trace those wires, might find the receiver.

One of the wires is just for the unit lighting, the other does go up inside the boiler. I’ll get the unit apart below and have a look, only held in with sealant I think lol

Your kitchen fitter needs to be shot, why must they always box boilers in so tight we can't get the covers off to maintain them?

I know! Crazy! Another 20mm and it would have been ok I think. There appears to be some kind of box down the back between the wall and units underneath the boiler. Hoping it’s the receiver!

Yep, that looks like the one, looks really accessible

It’s not in warranty. Why would it be void?

Because the manufacturers clearances have not been adhered to
