HVAC system wiring

Wiring will differ depending on if your system is a standard gas or electric system or if your system is a heat

pump system.

Standard HVAC system wiring

Figure 18 shows the wiring diagram for a standard gas or electric HVAC system. Wiring colors are typical

thermostat wiring color codes.

Note: For typical central heating/cooling systems, leave jumper JP1 installed. If you have separate heating and cooling

system transformers, cut jumper JP1. Wire RC to the cooling system transformer and RH to the heating system

transformer.

Note: Wire R to either RH or RC for common transformer HVAC systems.
