Google nest thermostat wiring

[Sundance67]

I purchased the Google nest thermostat, did the compatibility test and it simply said it could be compatible with my system prior to purchase… I have removed the old thermostat and The labels on the old Tstat do not match the labels on the Google nest thermostat , for instance there is no RH or RC on the Google nest thermostat … My old thermostat only has two wires one is connected to RH With a jumper to RC . The other low-voltage wire is connected to the W … I have a natural gas forced hot water system. Now When I go to the Google app it said it’s not compatible !! I’m at a dead end here and would appreciate hearing from a person who has knowledge in this area so that I can determine how to resolve this because I have four zones !  The goal is to replace all four thermostats with the Google nest T-Stats.

Hi Sundance67,

Thanks for reaching out. I'm sorry to hear that you're having an issue with wiring your Nest Thermostat. I'd love to know more about this and I have a few questions:

• What type of Nest Thermostat do you have?
• Could you share a photo of the wiring of your current thermostat?
• What's the make and model of your current thermostat?

Thanks,

Edward

Hello there,

Hey Folks, I’m sorry about the late reply but I just ended up upgrading from the nest thermostat to the nest learning thermostat where a C wire wasn’t required for a two wire system . Cost me a few more dollars but it probably evens out when weighing the cost of bringing in a Nest pro to resolve the issue … I installed them myself, and the problem is corrected, no more headaches .

thank you for the replies
