I am attempting to replace my Trane ACYSTAT008b thermostat

Customer Question

Hi, I am attempting to replace my Trane ACYSTAT008b thermostat with Nest gen 3. Problem is that the trane wiring has no identification on the wires so I have no idea where to put them on the Nest. The Trane has 10 wires that go into a plug on the Trane thermostat. Trade thermostat wire colours are brown,white,grey,purple,blue,green,yellow,red,orange,pink.

I know it is not the answer you want, but the Nest 3rd generation is not compatible or designed to replace your Trane ACYSTAT008b

Thank you for your reply but that information is incorrect. Neighbours with he same system had already had it fitted so I have had a local technician carry out the work. The system is compatible.
