Hi,

Our old mechanical honeywell room stat is starting to play up.
Time for a new one.
Had a look around the Honeywell website and came across this
chap;
http://europe.hbc.honeywell.com/prod.../pg_cm900.html

The CM907 looks like a replacement possibility and gives us the
ability to programme different temps for different times of the day!

Has anybody any experience of fitting one?
I presume the three wires that feed the existing thermostat are ok?

Any other mfcr possibilities?

Thanks,
Matthew

Hi Matthew,

Can't help you with other options, but here is a similar discussion
about 3 weeks ago. You must only connect two of the wires, *not*
Neutral! If you decide to follow the steps in my closing posting on
that thread, note that I am really a DIY newbie and may have messed
up; proceed at own risk.
