Sure! First, please make sure to disconnect any power sources before starting the wiring process for safety reasons. To wire the thermostat to the Advent Air RV AC unit, you're going to need to connect a red, white, yellow, and green wire from the thermostat to the AC unit. 1. The red wire supplies power, connect from RH terminal (Thermostat) to R terminal (AC unit). 2. The white wire controls the heating, connect from W terminal (Thermostat) to W terminal (AC unit). 3. The yellow wire controls the AC cooler, connect from Y terminal (Thermostat) to Y terminal (AC unit). 4. The green wire controls the fan, connect from G terminal (Thermostat) to G terminal (AC unit). Please note, some AC units may not use a green wire for the fan, and instead combine the control with the yellow wire, in which case Y and G would be linked together. This can vary based on the specific model of the AC unit and thermostat. Always follow the instructions that come with your specific devices.
