Hi,
As winter seems to be arriving, I'm finally going to install my Honeywell CMT927 (wireless programmable thermostat) this weekend. I'm an incorrigible miser when it comes to electricity (delighted now that carbon footprints are all the rage, I can hop on that bandwaggon, but my stinginess has nothing as noble as environmental concern behind it). Anyway, I was going to just take the power feed from the same FCU as the boiler. But it has occurred to my parsimonious mind that it's pretty wasteful having the thermostat running for six months of the year when it's not doing anything. So I'm inclined to give it its own FCU so I can turn it off next spring, but does anyone have any idea how much power these things actually use? The documentation that came with it doesn't say, and I can't even find the thing on Honeywell's website.
Cheers!
Martin
