wireless thermostat

Getting fed up of getting unreasonable quotes for what should be a relatively straightforward install of 2 x stats.


With that in mind, I wondered if it's possible for me to take a different approach and install wireless stats myself?


In the downstairs utility, I have an analog timer - and beside that, to switches - one each for upstairs and downstairs - and when both switched off, then that covers hot water only. Therefore - in effect - there is 3 zone control in place already. All I need is that stats.

How difficult would it be to swap these out? What wireless stats would people recommend?

Just remember that wireless stats are not totally wireless. The receiver must be hard wired into your heating system. They should also be wired to the SWL of the motorised valve for the circuit that they serve.

Can the main receiver not be wired in where the switches for the two circuits are? When the upstairs 'stat calls for heat, then the circulation is switched on. When the downstairs 'stat calls for heat, the circulation for downstairs is switched on. Am I missing a trick here?

In any event, there is NO direct access to the downstairs valve as the original plumbers have dropped it in behind a plasterboard wall!

Have you motorized valves in the system? If you have then the stats/receiver must be wired directly to these! It is the motorized valve that switches on the boiler and circulating pump and not the stat or even the time clock.

Break the plasterboard wall and install an access hatch. What happens when the valve fails? I have not known any to last forever!

sure -but presumably this is wired back to the 'on/off' switch at present, right? - so ...what I want to do is use that existing wire - and remove it from the 'on/off' switch - and attach it to the wireless receiver. The same for the wire from the upstairs valve.

I hear what your saying - and this has been highlighted to me on a number of occasions. It's very frustrating that the b&st*rds placed it there in the first place - and even then, I'm not 100% sure - it's just that it doesnt appear to be any where else. I'm aware that these valves fail easily - and I'll have to break through the moment that happens - I'm not going at it right now.

Hello Lads,

Hope I'm not breaking any forum rules here but wondering could you advise on what appears to be a straightforward query I have:

I currently have an immersion type analogue timer wired to my boiler - on, off and 24 hr. clock feature. What is involved in swapping this out and replacing with a wireless thermostat - Is it simply a matter of using current wiring in place to analoue clock or is there more to it. I'm a bit of a Noob where it comes to wiring etc. so be easy on me!

Also, any recommendations as to type/brand to go for?

Tks.

Any thoughts. Am anxious to get something sorted here!
