worcester dt20 twin ch prog n room stat, question

[TFGplumbing]

Got a call today, custards got no heating but they gt hw. The Roomstat unit is apparently dead no display(could have been dropped he said), batteries changed apparently still nothing.
Are both these units coded together? can I just get a new thermostat unit.

cheers boys

Well anyway, I fixed the room stat, batteries wernt in proberly. But the boiler(worc 37cdi) still wouldn't kick up properly only working on low flame. Phoned Worcester and they had me Reset the PCB, that cracked it! another happy customer =)
The units aren't coded together and can be brought separately, But hell the stat it self is £187.00 (retail)

Yep you're right. Those dt20 rf's are crackers though, we've been fitting them as standard for years! Very simple and reliable these days, customers love them. Think around 140 quid we get them for.
