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.

Remember the is a time and temperature controller if you want to use as an ON/OFF controller please ensure you OFF times are set to LOW temperatures for example at 8:00am I want the boiler firing to 21°C at 10:00 I want the boiler to go OFF at 5°C so ensure all so called OFF times are set to LOW temperatures.

Turn up your outside thermostat in the outside unit.
You should have about 3 degrees difference in one stage to the next. So I would change the thermosat with one that has three stages of heat.

Is there a setting on your thermostat that makes the unit stay on for 10, 15, 20, 25 minutes after you reach set temp. You can change this setting by looking at your manual for the thermostat. Not sure if there is one for this thermostat but mine has one. Mine was running 15 min after set temp and making it cool down 2 degrees lower than set temp. Hope this helps.

The thermostat will not cut off the A/C until the thermometer reading gets to 76.
If there is not a heat source near/behind the thermostat which is causing the thermometer to read higher than actual room temperature, it sounds like the thermostat thermometer is out of calibration.
There are ways to calibrate it, but much to involved to go into here.
One solution is to just set the thermostat at 80, knowing that it's really set on 76.
Another solution is to replace the thermostat.
