Is my PECO TB155-48 thermostat compatible with nest?

[noahe7700]

Hello, 

I have moved into a new apartment and would like to upgrade my thermostat to a nest device. I am unsure if my system is compatible, and I am unsure how the wiring correlates to the nest wiring. I was able to confirm my thermostat is operating at 24V, but I do not know if the wiring for this system is compatible with the nest. Here are the links to the TB155 data sheet and installation instructions:

Thank you,

Hi noahe7700,

Thanks for sending the file! Based on the information you provided, i am here to help!, it seems like your HVAC system should be compatible with a Nest thermostat.

For extra confirmation, you can do one of two things:

1. Tell me the specific wire colors connected to your current thermostat. I can then check them against the compatibility checker for you.
2. Use the Nest compatibility checker yourself: Compatibility checker. This tool will ask you some questions about your system and let you know if a Nest thermostat is a good fit.

No matter which option you choose, I'm here to help!

Best regards, 

Chris
