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.

This my situation exactly. Changing from a 6 wire manual round Honeywell thermostat to a 5 wire Honeywell programable. Is there a way to maintain all functions?

Look at the instuction booklet (or on the T-stat board) for a switch for the reversing valve.
Some systems reversing valves are in cooling mode when energised, some are in cooling mode when NOT energised.
You are looking for the switch (Usually very tiny, or a different jumper setting) that will change the position of the reversing valve when calling for heat/AC.
This is not a switch like the typical "ON OFF AUTO, HEAT COOL EMG HT switches. It will be on the board itself or the back of the T-stat.

I connected the blue wire to the R and the white wire to the W on the old thermostat and shoved the new Honeywell 5-1-1 Day programmable thermostat up the first guys *** that i ran into at Canadian Tire
Thanks for your help

Every thing the same except take your blue wire and replace the yellow for it. So when you hook it to t-stat goes like this
Red to R
White to W
Green to G
Blue to Y
