During the upgrade of our CH system last year, our eminently satisfactory Honeywell thermostat (located in the hall) was replaced with a simple Drayton type (the sort with a large circular knob on the front).
I have noticed, by listening to the clicks made by the bimetallic switch inside it, that it appears to have a 'spread' of about 2 degrees - ie once it switches on, the hall temperature has to rise by 2 degrees before the heating switches off.
Not surprisingly this means, particularly at this time of year when the temperature is close to the ideal setting, that the heating sometimes comes on for much longer than necessary.
I know I would probably be better moving the stat to say the living room but, for several reasons, don't want to do that. Instead I would like to replace the Drayton thermostat with one that will control the hall temperature much more accurately (perhaps one with a digital display too, although that is not important).
Can anyone recommend any suitable models please.
Many thanks,
V
PS Should have mentioned, current stat is fed by a 3 wire cable, + / - and switched. The power is only on when the boiler is on ie controlled by the CH timeswitch. This may limit my options perhaps?
