Hello,

Once you mount your nest thermostat back plate with wiring input mount, you will connect White Wire to W1, Red wire to R, then Black Wire to C.  This should allow new nest thermostat to work.  Make sure in the app to assign wires and it should control system correctly.

Hi folks,

@mishalooh, thanks for posting here in the Community forum and for showing interest in our Nest Thermostats. 

Where are you located? From North America or Europe? And what is the make and model of your HVAC system and your current thermostat? Also, since your current thermostat wiring photo does not clearly indicate its terminals, please help us with an image of your HVAC control board where the thermostat wires are connected. In that way, it will help us determine its compatibility with our Nest Thermostat and recommend the Nest Thermostat suited for your system.

On the other hand, you may use our Compatibility Checker to help you determine if a Nest Thermostat is compatible with your heating and cooling system.

I appreciate your help, @mchavez7476. 

Best,

Zoe
