Connecting a dehumidifier to a Nest Learning Thermostat

I have a Nest 3rd Gen Learning Thermostat that I want to install. On my current thermostat there is a purple and a black wire that are plugged into a U1 port for a whole house dehumidifier. What port can I use for the dehumidifier and do I use the purple or the black wire?

Hi rboomer,

Thanks for reaching out in the Google Nest Community forum. I'd like to take a closer look at it. To confirm, in what country are you located? What is the make and model of your system? Please take a photo of the wires connected to your system's control board. Ensure that the labels of the wires are visible.

To send a photo, click this link then scroll down to your response and hit reply. Check for the camera icon or click the three horizontal dots to expand the toolbar.

Best,

Jenelyn
