Two room thermostats

[dewalty]

Hi

I have a Honeywell CM907 that has been working very well, add a requirement to have a bedroom at a set temp and I have a problem.

In my current setup the CM907 is in the stairway/hallway area. Sometimes a log burner is going downstairs. The temp set on the thermostat is reached and off goes the boiler, however that leaves the bedroom gradually going colder.
I have been looking to see if you can add a remote sensor to the CM907, which you can do but that just disables the on board thermostat
What I would like is an additional thermostat.

Would two cm907's in parallel work, or is there a more elegant solution?

Thanks

A second stat would be pointless.

You need a separately zone circuit with its own sat and control of the boiler.


Or...

Get a CM92x and pick a better location.
