Hi all! Im about to install a Nest 3rd Gen thermostat and was hoping members could offer some advice before I start.
I have a Y plan CH system; boiler in the garage, timer and fused spur in the kitchen, CH thermostat in the hallway, and pump, wiring centre, and 3-way valve in the upstairs airing cupboard.
I intend to install the heat link inside the airing cupboard adjacent to the wiring centre. I have some 3 core 1mm2 flex that I would like to use. I would use one lenght for L, N, & E, one length for the 12V supply to the thermostat/ display, and one length to connect to the HW thermostat and 3-way valve for which I will use all three cores, including the earth. I expect the cable lenght to be about 30cm. Is it acceptable to use the green/yellow cable in this manner, and is 1mm2 cable OK?
Also, as I will not have a permanent supply from the fused spur to the wiring centre, can I use one of the now defunct cables from he old timer to the wiring centre? I've had a look behind the timer and see that I can easily connect to the 230V supply to the timer.
Any advice would be greatly appreciated.
Thanks.
