Hi all

Seem to be posting zillions of q's today!
What is the group's opinion of wireless room stats?

I know the installers like them because they don't have to run cables.
Are they overly complex for a domestic installation?

I am being quoted for a system that will have a programmer on the hot water
zone only, with upstairs and downstairs heating being separately controlled
(2 heating zones) by individual wireless stats.

Anyone like to comment on this set-up?

TIA

Phil

Trying to get cables run neatly from the control point to the stat position
can be overly complex in many cases!

We've had a Honeywell CM67RF wireless programmable stat in our church for
several years and it has been totally reliable. The CM67 is a great piece of
kit, especially if you take time to really understand all it will do. As a
basic example in your case you could set it to have the bedroom zone at 18C
from 1800-2200 and then bump up to 21C from 2200-2230

OK, if you have to. They are basically the cheap option, rather than running
cables and redecorating.

Are they overly complex for a domestic installation?

No. They are specifically intended for domestic installation. I would not
consider using them in a commercial or industrial environment.

Yes. It is a very good idea. However, I would put the heating through a twin
zone programmer, but set to 24h on the heating side. Although not entirely
necessary, it has 2 advantages. Firstly, it provides a convenient switch
when you want the heating off. Secondly, it can help prevent teenagers
overriding the controls at night because they want the heating on and the
window wide open.

Yes mine did that last night (she'd just washed some garment which she
wanted to wear this morning - so, perfectly reasonable solution to the
teenaged brain.) Bless.

Running cables when everything is decorated and carpets down is a PITA.

No, they are super devices. I have a Danfoss TP75 (didn't like the CM67
which everyone raves about), it just sits there and gets on with the job
controlling the temp for our comfort. I do have the receiver switched
supply feed through a normal programmer so that when I want the heating
off it's really off not just off until it gets cold enough. Not to
mention the noise of creaking pipework at 3AM isn't welcomed...

With you on this one.

Didn't know about the teenage approach to global
warming though (a couple of years to go for me on that one).

Honeywell CM67 RF works well for me, can experiment with different
positions in the house (or even move it for different times of year
etc)and will work with more than 1 thermostat with the relay box.

Do they do tank stats as well - impossible to run a wire neatly
