I want to install a nest thermostat to control the 3 zones in my house. But there isn’t a CWire currently connected to my existing thermostats and when I installed the first NEST, it said it wasn’t getting enough power. But I DO have an extra wire in the cable coming to the thermostat, and I’m curious if I can simply connect them to the C connector on the transformer. I’ve mapped out the wiring for each zone,
I also have a photo of the wiring, but it’s a mess, so I thought it better to use the schematic…. I can attach if necessary
