I have a 2 zone system, i believe powered by an ultra zone board and Live chat told me my wiring was not compatible but i just wanted to make sure . Its a conventional system, with the zone 1 thermostat having RH to RC jumped with W Y B and G wire, and the downstairs has  Rh to RC i believe with W and Y. . Its a conventional system without a C wire and its not heat pump so it would not be the reversing valve to my understanding

Thermostat is robertshaw 9500 ,  have heat and cool system forced air

Hi realcheesydorit,

 

Thanks for posting! I'm happy to help you with this compatibility check. I used the Thermostat Compatibility checker tool and it says that your system is compatible with the Nest Learning Thermostat. However, according to the Zoned system compatibility with Nest thermostats article, "If you have a Nest Thermostat and a zoned system, you’ll need to connect a C wire or install the Nest Power Connector."

 

Regards,

Axel.
