Hi @Phero,

Thank you for contacting us about your thermostat wiring. To provide the most accurate assistance, we would be grateful if you could send us a clear photo of the wiring connections on your old thermostat.

Please ensure that the photo captures the following details:

Wiring colors: Note the colors of the wires connected to the thermostat.
Terminal labels: Identify the labels or numbers on the terminals where the wires are attached.
Thermostat brand and model: If possible, provide the brand and model number of your old thermostat.

A clear photo will help us determine the compatibility of your new thermostat and provide specific wiring instructions. If you would like to check it by yourself, you can go to our compatibility checker, here you can confirm if your system is compatible.

I’ll be waiting for your response.

Regards,

Josh

Hi @Phero,

Thank you for your inquiry about the compatibility of our Nest Thermostat with your existing thermostat.

Unfortunately, based on the image provided, it is difficult to definitively determine where the wires are connected on your old thermostat. This information is crucial to ensure proper installation and functionality.

To guarantee compatibility and avoid any potential issues, we recommend contacting our customer support team. A representative will be able to assist you in verifying the wiring configuration and provide guidance on the best course of action.

Regards,

Josh
