Wireless thermostat

[RobertPW]

Hi everyone

My house has a wireless thermostat to control the boiler. All works fine....until the batteries run out. I want to hard wire the unit but can anyone advise me on whether a fused spur would be a suitable solution with a 3amp fuse?

Thanks in advance

Only if it is using a 230V battery at the moment.

I had same problem, cure was two wireless thermostats. They are not in the same rooms, and both have different times when they are active, so if all batteries OK then one sets night temperature, the other day temperature. However if one fails then not left without central heating.

Main advantage is should one fail, then other one will insure nothing freezes up, clearly if in the house we simply fit new batteries, but if not in house, then nothing freezes.

Is it really that difficult to change batteries once in every couple of years? Most likely the thermostat has a low battery warning symbol on it as well.

Just to clarify, the thermostat has hardwire terminals as well as batteries. So it is designed to be hard wired.

What supply (voltage, AC/DC) does it require to those terminals?

You said it was wireless.

If it works on a battery then you cannot run it on the mains.

Was there previously a non-battery thermostat?



What is the model number?

And you're sure, are you, that those are terminals to allow a 230V supply to be used to power the electronics, not volt-free contacts to be used for hard-wiring as an alternative to the wireless control for the boiler?

I have a portable Sony radio/CD player which will work from either 230V or an inordinate number (but not 150) of D cells.

Is that how thermostats are made?

Perhaps it only has a battery back-up and that is why it seems to be a pain to replace them.



We have gone from wireless to not wireless, so who knows what it is?

I doubt it.

Who knows.

I've got a Drayton Digistat, and that's a PITA to replace the batteries, because unless you wait until it shows the low battery symbol it loses all the stored settings when you take the batteries out. Problem is it stops talking to the receiver in the boiler long before it thinks the batteries are dead. And don't get me started on how the tw@s who designed it decided to store the temperature settings for each time period .

But it has no terminals for wires of any sort.
