The programmale 'stat is no longer talking to the receiver, even from close
range. The batteries were OK but I put in new one (2 batteries of 2 AA cells
each) just in case. It used 333MHz signal, so is there any way of testing
this? I don't have any radio gear at all.

If I have to replace it, there was one recommended in here a few years ago -
a lot cheaper than the Drayton - and I bookmarked it but now can't find it.
Can anybody recall what it was, please.

Now , what would be a good, easy to use, sort to get? Although this is 7 day
a 1 day would do. It's for a combi.

We have a Salus. I's been fine for the couple of years we've had it.
I've replaced the batteries in the transmitter once.

Thanks, that looks like the one. Pity that I can't find out what's wrong
with the Drayton; the receiver seems to function - all the buttons work and
the override is what I'm using for manual on/off.


perhaps you need to re-pair the reciever and transmitter again or check
what radio channel number both are set to? (they should be the same)
Full procedure on receiver - OK - full pairing procedure - FA.
Flow chart confirms failure of transmitter.
It was fitted 21 years ago all but about 3 weeks so it ain't done too badly.

Salus RT510 on order from Ebay, due Mon. - Tues.

Thanks for all the suggestions and help. Now, I /must/ remember to turn off
the boiler!

A common failure is the big capacitor in the receiver. Available on Ebay for just over £4
