Hi Owen21,
Thanks for reaching out. I'd like to take a closer look at it. A few questions: in what country are you located? What is the make and model of your system? If you already have a Nest Thermostat, what type is it? Could you please take a photo of the wires connected to your system's control board? Ensure that the labels of the wires are visible.
Best,
Jenelyn
