Nest thermostat

[Stevenhunruhsr]

I purchased a Google Nest learning thermostat item number T3############s. I have a 24 volt system in my home. At the thermostat I only have two wires one white and one red. I need to know what to connect to the base as the selection shown are neither just white or just red. There is a W1 and Rh but I am not sure what to connect the wires to. There are many selections on the base but I am unsure on what to connect to. There are no designated positions on the thermostat or on the aquastat that match any of the selections on the base. Any help or suggestions would be greatly appreciated as this was supposed to be an easy install. Thank you

Hey Stevenhunruhsr,

Thanks for posting here.

Based on your description of your current wire setup, you possibly have a heating only system. 

The white wire usually goes to the W1 terminal and the red wire to the Rh terminal on your Nest Thermostat.

It would also help us if you can post a photo of your current wiring.

Regards,

Ryan
