How to Wire a Thermostat on a Gas Rooftop Unit

This video on thermostat wiring focuses on rooftop units. The rooftop unit being discussed is a single-stage heat and single-stage cooling unit. The presenter, Ryan Hoger, explains the terminal designations on the control board, emphasizing the standardized color-coding system for thermostat wires, though variations can occur based on project needs. Viewers will learn a step-by-step approach to the wiring process, assigning colors to each terminal, such as black for common, green for the fan, white for heat, yellow for cooling, and red for hot. The video also explains the differences for multiple-stage units, suggesting blue for the second stage of cooling. Hoger also highlights the importance of matching colors between the rooftop unit and the thermostat for proper functionality.
