Battery powered wireless thermostat receiver

[M.Joshi]

Does anyone know if a wireless room thermostat is available where the receiver unit is powered by batteries?

 

[kay-jay]

the receiver units are wired in to the boiler, but its easy to do. how else would the receiver unit communicate with the boiler? something has to be hard wired afaik

 

[M.Joshi]

The current wired thermostat is in the hallway which is usually quite warm. I want to remote the thermostat to a better location in the house.

The only connections at the existing thermostat are 2 wires for switching i.e. call for heat. I may be able to obtain a neutral from a light switch below but not an ideal solution.

Many manufcturers (Honeywell, Horstmann, Salus, Sunvic etc.) do wireless thermostats with an external receiver which can be wired anywhere however, they require a live and neutral connection in addition to the switching wires.

kay-jay I think I understand what you mean now - the receiver unit could be sited near the boiler where there is a live/neutral and replace the existing switching wires (in the boiler) from the old thermostat with those from the receiver unit.

If it is possible I would recommend a hard wired I'm not a big fan of the wireless I find they dont tend to last that long.

But thats only my opinion.

I think you're right as people are always complaining about the receiver/thermostat losing pairing. It would start to become annoying waking up on cold mornings with no heating!

I may try experimenting by reducing the heat output from the radiator nearest the thermostat. It only has a lockshield and normal valve.

I'm a I'll confused here

Receiver unit ( boiler end) is usually powered by mains. Just piggy back in spur or inside boiler for power

Transmitter unit ( thermostat) is usually battery powered and can be put anywhere

yes and the wired stat usually in the hall will be replaced with a battery powered stat. this communicates wirelessly with the receiver which in turn communicates with boiler by virtue of it being wired in

Am I the only one confused here?

 

[M.Joshi]

I'll try to explain the scenario better for those who are confused:

The current thermostat is in the hallway. Two wires come in to the thermostat - live and switched live.

I want to replace this thermostat with a wireless one as the current location is always relatively warm compared to other rooms in the house.

Initially I was planning on placing the receiver of a wireless thermostat where the old thermostat was. This is not possible as the receivers I have looked at require a live & neutral in addition to the switching wires.

As kay-jay pointed out, the receiver can be sited near the boiler where there is easy access to a live and neutral as well as the switch contacts from the old thermostat.

I wanted to install the receiver in place of the old thermostat as it is fairly central and would be able to receive the signal from the remote thermostat anywhere in the house easily. Having the receiver near the boiler (large metal box) can impede the wireless signal from the remote thermostat.

 

[Leo21]

Ah I see now. Just use a decent quality stat like honeywell. All receivers are wired close to the big metal box and all the good ones work.

 

[ecowarm]

Check the cable it may have 3 core, 1 cut short, worth a look anyway

 

[dancinplumba]

you can site reciever as far from big metal box as you want, as long as its wired to big metal box it will be ok
imo

Yes, ideally I wanted to install the receiver in the location of the old thermostat so that it also covers up the redundant space. As I mentioned before, I could probably obtain a neutral from a light switch below but not an ideal solution. Hence why I asked if a battery powered receiver was available which only requires 2 connections for switching - like a normal thermostat.

All the wireless receivers I have looked at so far require 4 connections. Live, neutral, live-supply, switched-live. So, I only really require an additional neutral as the live and live-supply could be the same.

if receiver where old stat is where you going to put thermostat transmitter ? dont take neutral from another circuit.
put receiver next to boiler with clear view to thermostat/transmitter

I was thinking of putting the remote transmitter in another room which is always colder.

I was hesitant about taking a neutral from another circuit as isolating the central heating supply from the fused-spur may leave sections of the wiring still connected.

In any case, after reading all the problems people have with wireless thermostats pairing or not working reliably, I may just stick with the wired thermostat and lower the heat output of the radiator nearest.

 

[dancinplumba]

best to try this first, the best wireless imo are honeywell and delta dore

 

[ecowarm]

as above dont take neutral from another source
