help....., my 4ys old 30cdi keeps losing its transmitter signal, the colon on the reciever flashes and i have to press the ok button to reset the signal. i have rang tech support and they weren't the helpfullest, man suggested to put fresh batterys in which i have done today, and then if not solve the problem to buy new roomstat..is this the case or should i try something else.. many thanks.............
Hi, try moving it closer to boiler in case something is interfering with the signal.
Check for any new electronic devices between the boiler & 'stat eg PC, play station, cordless telephone base set etc.
The signal from 'stat is VERY low power and it doesn't take much to 'kill' it.
before doing anything drastic if it is a worcester thermostat there is a forum i found by entering Bosch Worcester 30 CDi in google and found 13 bosch engineers on line for questions, might be worth a try.
Normally such things either work or not so assuming good new battery fitted and moving it closer makes no difference must assume faulty.
Not cheap to buy but very easy to DIY replace. receiver slots in with just a low voltage 4 pin plug on short ribbon cable.
