Hi,

All you need to do is look at the wiring diagram on the back of the old room stat, you will have the following:

(normally wired with these colours)

OLD COLOUR CODING

Live (sometimes called common) - Red
Neutral - Blue
Switch Live - Yellow

NEW COLOUR CODING

Live - Brown
Neutral - Grey
Switch Live - Black

All you need to do is wire up the new stat with this in mind. (please note: if the wires are not colour coded like this then do not proceed and get an electrician)

Any problems or questions let me know

I hope this helps

Steve

SOURCE: changing a room thermostat a potterton to honeywell t6360

I think I've done it - but don't take this as absolute truth.
For the Honeywell T6360B the original Potterton wiring should be rewired as follows:
Brown [Live] goes to terminal 1; Blue [neutral] goes to Terminal 2 and the yellow/green [which is not an earth but a switched live - i.e. gives live to the heating system when the thermostat clicks in] goes to terminal 3.
Obviously all done with the power isolated and when it was switched back on we had heating again :o)
It's been on over two hours now and all seems fine.

SOURCE: wiring honeywell digital stat

Hello davem1952,
The way you wire it will depend on how the other end of your three wires are wired into your heating system. This link http://www51.honeywell.com/pacific/common/documents/DT200_Specifications.pdf
shows the various methods for wiring it and take into account the type of setup you are dealing with. You'll need to find the wiring detail ( last page) that corresponds to your setup..
Hope this helps..
Reagrds,
Rick

SOURCE: installed my thermostat and the heat keeps

Make sure red wire is on R terminal, white wire is on W terminal. Also look for a short in the thermostat wire.
