Fitting Heatlink E to replace Honeywell T40 thermostat

Hoping someone can help me figure out which is the common wire on my Honeywell T40 thermostat. Looking at the diagram on the thermostat itself it looks like it’s the live wire. Does that seem right?

Hi there @WillKlug 

 

Thanks for reaching out. Could you provide us with a picture of it so we can check? Do you have a previous diagram for the last thermostat?
