Hello. Im looking get a Nest smart thermostat to my Glow Worm 30cxi but after inspection of my current thermostat wiring, im in need of some help. I have two wires going to the current thermostat, labled L & Y1. (For some reason who ever fitted it has used twin & earth cable) this links to a voltage free connector as you can see in the pic. The L (Blue) goes to the Blue on the voltage free connector & the Y1 (Brown) goes to the pink. Now im guessing this is Switch Live & Call for heat wires?
Is nest compatible with my system with just these two or will i have to spur off of a few others?
Any advice would be great.
Thankyou
This is where the volt free link connects to...You can see the blue & pink wires along with 3 others on the plug. Black, Brown & Red
