Worcester 24i and Honeywell CMT921

[daren_28]

Hi,

looking for some guidance please on fitting a CMT921 to Worcester 24i.

Taken a couple of pics for ease.

I'm not an electrician by any means but fairly handy but obviously want to get this right hence this request.

Found this previous thread but if I'm honest the abbreviations aren't meaning a lot to me....... http://www.diynot.com/forums/viewtopic.php?t=240138

Im grateful for any and all advice on this fitting.

Thanks,

Daren

What controls do you have at the moment (programmer and thermostat)?

Hi, no thermostat at all and there's a push in clock timer (if that makes.sense) with another dial on the boiler for varying temperature.
