Hi Guys,
I'm a newbie here on this site and was looking for a little advice. I'm quite comfortable with electrics, but not so much for heating. I'm trying to hook up a Nest Learning Thermostat to my central heating system. The programmer is a Drayton Tempus 7 and the boiler is a Potterton Suprima 60L. There is a Drayton wired thermostat already installed in the hall which I assume comes back to the programmer here somehow.
I've posted pictures of the Tempus 7 programmer as is, and the wiring diagram. I'm assuming I can simply take a spur from the junction box behind the programmer to the Heat Link 240v to power it. However, the call for heat has me a little confused - can I simply wire the HeatLink into slot 4 on the tempus below, as this seems to control the CH circuit.
Obviously there is an isolating junction box so I can isolate all the electrics safely too.
Any help would be great!
