Wiring new thermostat

[Steve0508]

Still have not managed resolved fitting my thermostat. Not sure where to connect the three wires. I have a red, blue and yellow wires on may old thermostat. But not sure which wire connects to which block on thermostat.

Are you able to advise.

Kind regards 

Steve

Hey Steve0508,

Apologies for the delayed reply. I wanted to follow up and ensure you are good to go. If you are unsure on what your wire labels are, I would recommend checking the system control board. It would have more details on what the wire exactly controls.

You can also have a Nest Pro come out and take a closer look. They would be able to install the device and ensure everything is working properly. Please let me know if you have any questions.

Best regards,
Jake
