When installing a Nest

[mutley racers]

On an Old S plan system, do you just replace the programmer and install heat link and use a plug to supply the Thermostat or do you wire the heat link into the wiring centre and re use old Thermostat wires for t1 t2?

Cheers

Depends if there's an existing wired thermo and they want it in the same spot

If yes then I do

Thanks Shaun. Super quick response that.

I do either or. Depends on what’s the customer wants.
