Boiler & Wireless Thermostat problems

[TheEsoo]

Greetings all,

I have a Potterton Promax Combi HE Plus (33 HE A) and a Potterton Famoso 601 RF Wireless thermostat.

The boiler is currently flashing battery low/empty, I have obviously changed the batteries in the thermostat and followed the "recommisioning/linking" process, however the thermostat isn't picked up and it just keeps flashing. It does seem to pick it up occasionally because if you set the heating to constant it will randomly come on and then go off (very annoying at about 3am)...

Can I just buy a cheapo wireless thermostat and see if it works, or do I need to buy a specific one for the boiler? I'm hoping its just an thermostat issue and not one with the boiler :E

Does the problem go away if you move the control unit (transmitter) nearer to the relay box (receiver)? If it does, then the problem is due to loss of signal between the two transmitter and receiver. This will be due to the type and number of walls between them. The only solution is to re-site one of the components.

Sorry I probably should have stressed; when I'm trying to relink them I put the thermostat right next to it and it doesn't pick it up

Bump

I really hope a "cheap" wireless thermostat would work, the Potterton is £122

Never buy cheap! It's worse than buying very expensive!

How old is the Famoso - it's actually made by Grasslin? If it's still in guarantee, why not get it replaced?

If you want something better, go for a Honeywell CM927. You can get a new one on Ebay for £85.

It's not in guarantee, as far as I'm aware my girlfriend had her boiler fixed some years ago, and it flooded the place the next day. She went mental and demanded a new boiler, to which the company obliged and gave her it complete with the thermostat. I think it had a basic one year manufacturers guarantee at most

Will that work with the Promax Combi HE Plus?

Yes it will
