Programmable Thermostat, does what it claims

"I have replaced an old electro-mechanical thermostat with this one. Although it is expensive, I expect to recoup its cost with savings in my gas bill within about 15 months. I have used an older version with this saving in a previous house."

Very pleased!!

Pros: Easy to install , Easy to programme , Useful added features eg holiday settings single button.

Cons: Nothing drastic.....advert shows backlight is blue but is actually grey.

"Bought this to replace an 25 year old Honeywell analog thermostat and am very pleased with the results. The CM 907 gives great versatility with 6 programmable periods per day. Have found that to be more than I need but it's easy to disable periods if not needed and 4 periods has been the optimum so far. Very easy to swap the new unit for the old one. 2 wires and the whole thing done in 15 mins. Programming instructions were easy to follow but with hindsight I should have used the default settings for a week and then edited from that to what I need. Temperature control is so much more precise than before so far less overshoot in operation."

Excellent Control

Pros: accurate control, easy installation, simple programming

Cons: nothing

"Very easy to install and set up. Ten minutes and it was working. Very pleased with the Optimised mode (set via Installer options). House is at the right temperature just when needed now. Much less waste. Early indications are that gas consumption has dropped as a result. Very satisfied!"

Excellent, easy to use device

"Easy to fit, easy to use straight forward replacement for 2 or 3 wire thermostat - would be good if an option to power the unit from the mains where neutral wire exists was available but it does just what it says in the specification. I guess I may have to wait a while to see if it reduces my heating bills but it certainly stops the female members of the family turning the heating "up a bit" everytime they pass the thermostat so it must be good"
