Replacing a Worcester DT20RF wireless thermostat with wired room thermostat

[fingersuk]

Hi,

Currently have Worcester 30Si boiler is fitted with DT20RF, and a RF room stat that's roughly 5 years old. Having nothing but problems with pairing the thermostat it seems to drop out quite a bit recently. (Turned all RF kit off in house to diagnose too and nothing new). I've tried repair with learn mode on as per manual but its physically not working anymore. I have no doubt it'll start working when it wants too, put some brand new batteries in again and still nothing.

So my question is, if I leave the DT20RF in the worcester boiler can I hardwire a normal room thermostat so the DT20 still does the timing's but switches off when the thermostat isn't calling.

Short answer is no.
If you leave the DT 20rf connected it will constantly look for the rf room stat and do the same as it is at the minute(where it loses signal)

Did you get it fixed? I had a similar problem with my DT20rf (mk1). I followed the instructions (ie learn mode etc) but it wouldnt re establish the link. So, today I took the transmitter apart to look for any obvious damage and found the tiniest amount of corrosion on one of the battery terminals, I scraped it off with a knife and went through the learn procedure again...bingo! link established in a micro second....might be worth checking your terminals before binning it?!

Thank you for the very useful tip. I had the same problem and was going to purchase a new kit. Fortunately I checked for tips online and found yours. It worked!
