Replace trane z-wave thermostat tzemt400bb32maa with Nest Learning Thermostat

[get2ab]

Hello,

I have two trane z-wave tzemt400bb32maa thermostats in my house and want to replace both of them with Nest Learning Thermostat.

Tried to check the compatibility with the online compatibility checker but wasn't able to find exact matches between the wires in the thermostat vis-a-vis the checker. I am attaching the pic of the current thermostat configuration.

Could you please help with the mapping of the wires?

Thank you

Hello get2ab,

I'm sorry for the late reply. I know it has been a while, but I wanted to ensure that everything was covered here.

Thanks for sharing your system information. Your system is a Nest Thermostat compatible. If you have a heat pump, connect the orange wire to the O/B terminal and the rest to their corresponding terminals on the Nest Thermostats. If there’s anything else I can help you with, please let me know.

Regards,

Mark
