Hi Anishadaven,
Thanks for posting here in the Community forum and for showing interest in our Nest Thermostats.
Are you located in North America or Europe? Is your current thermostat operated by a cooling system only? If not, could you clarify how are the wires connected to your thermostat right now? You may use our Compatibility Checker to help you determine if a Nest Thermostat is compatible with your heating and cooling system.
I'll look forward to your response.
Best,
Zoe
