No cooling option

[Jo42]

Installed the thermostat but no cooling option?  Have blue to c, white to w, yellow to g and red to r

I don't see a Y terminal, which you need to have cooling.

Your current thermostat looks to control a heat-only system.

@Patrick_Caezza  I am replying for my mom. We replaced an old climatol thermostat. It was both heating and cooling. The blue wire looks to be Y/C?

@Patrick_Caezza  Here is the wiring. Assuming we need a common but not sure where it would go since we can’t see a terminal block

@Kl08 

In that case, you will want to connect the blue wire to the Y1/Y terminal on the thermostat.

I would also strongly recommend that you install a C wire. If there is an unused wire in the thermostat cable, you can use it or the Google Nest Power Connector.

Hi andy3207, 

Thanks for reaching out to us. Your thermostat wires are compatible with our Nest Learning Thermostat and the Nest Thermostat E. You can check more about the compatibility of your system in this link. 

This is how the wires should go to Nest Learning Thermostat. 

 

And, this is how the wires should go to Nest Thermostat E. 

 

Also, here are some helpful articles that will help you set up your Nest Learning Thermostat or the Nest Thermostat E:
