Hello everyone,
I have a Worcester Greenstart 24i Junior combi boiler installed in my house.
I'd like to wire a nest 3rd gen thermostat.
The programmer wiring:
The thermostat dial wiring (RTS1):
It looks like the fused switch is wired in a programmer unit:
So switching off fused switch cuts off power to programer and combi boiler.
My question would be how to wire the nest heatlink? Seems that there are too many wires in this programmer or is this normal? Thank you.
