Drayton Digistat RF3 failed

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.

Salus ST620RF?

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)

One can be too close but not likely.

That'll be 433 MHz BWTH. If you have USB DTTV stick it might have the right chipset for the Software Defined Radio (SDR) sofwater to work. You'd then be able to see the bursts of RF data.

An the stat also appears to work with display, adjustment etc. Have you tried any pairing proceedure?

Have you gone through the wireless re-pairing sequence again or are you just assuming that the two units will still be connected after a battery change?

Don't buy the Honeywell CM927, I hear the LCD fails :-)

At our previous place about 10 years ago the Drayton failed after a couple of years (IIRC it was the receiver rather than the transmitter). I replaced it with a Sunvic, which was a pain to set up (unclear instructions) but once set up worked faultlessly for three years.

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

Find somebody with a radio scanner. I'm a bit dubious about the frequency as its normally a small group of channels inside the70Cm ham band that they use. Brian

The receiver seems to be working on all functions and tests.

Ordered the Salus 510 yesterday morning with delivery for Mon./Tues. Delivered about 1 pm today. Haven't had time to fit it due to finishing another bit of wiring and too close to PVR due to come on (priorities...).
