Honeywell T4R wireless range to boiler relay

[Ollie R]

Hi all, we have a house with solid stone walls with a combi boiler serving it from a block built outbuilding next door.

Currently there's a Siemens RDJ10 thermostat in the hall which is not much good as the temperature is very different in the open plan kitchen diner.
I was thinking of getting a Honeywell T4R as a I previously had a CM927 which worked very well, but if I'm wondering if the the wireless from the boiler relay in the outbuilding to the thermostat in the house is going to be reliable enough through all that stone and blockwork. Is it possible to wire the relay or can it be put where the existing thermostat is in the hall?

many thanks,
Ollie

Hi Ollie,

Thanks for your question - stone walls can be thick sometimes!!

Any members got any advice for Ollie?

If the CM927 wireless link worked well, I'd expect using a T4R (Honeywell's recommended replacement) to be fine also.

If you are running cables between separate buildings, I'd recommend consulting an electrician. (You need to be careful about the earthing and lightning/surge protection arrangements.) Wireless (or fibre optic) links avoid these issues.
