Yeah. Have your manuals handy if you get a furnace guy/electrician in. My electrician actually wired up my thermostat wrong when I got a new thermostat in.

Thanks, and to the other guys. But I am asking about a remote wireless thermostat. How does it know to talk to my boiler, and not her next door's?
As I said totally OT, and I do have a couple of good C/H firms I can get in to sort it.
Sounds like an awful idea in general. Think KISS concept. But you'd have to look at manuals. There's probably no single answer. (I was thinking of wireless control of the thermostat itself.)
I'd add that, where I live (New England), furnace failures can be basically catastrophic so any theoretical convenience advantages just aren't worth it.
Wireless thermostats are really common in the UK. I don't know about elsewhere. I'm interested how they pair (like Bluetooth) with the boiler.
Basically, the thermostat is in a living area and you set the temperature(s) to what you want, it senses them, and then talks to the boiler (in my case in the roof-space) to heat up (or not, via radio) the water in the radiators to satisfy that. It's a feedback loop.

That depends. Sometimes because they have encryption. It isn't hard to have shared keys of some sort. If there is no internet connection on the link (which is possible - I've never seen where both systems connect to wifi, but if they do worry!), and so you don't have to worry about malicious hackers and in turn the encryption is good enough even if done somewhat wrong.
Sometimes they are just send a radio signal and hope nobody else in range is using that frequency.
So again, there are too many different ways this is done to guess. Unfortunately they probably don't put this in the manual.
