Electric Heating Wiring Diagrams R or rc wire (power) connected to the r power terminal to power the thermostat. w wire (heat), connected to the heating control. g wire (fan) connected to the fan control to operate a blower in your hvac system. y1 wire (cooling) connected to the y terminal compressor refrigerant system. Many types of systems can. a heat pump with 2 stages of heating and cooling, a system with aux heating or one that has a reversing valve that needs to be energized. how to wire a 7 wire thermostat: 1). attach the red wire to the r terminal for 24v power. 2). attach the white wire to the w (or w1) terminal for the heat pump’s heating mode. 3).
Heating And Cooling Thermostat Wiring Diagram Collection The hvac wiring diagram thermostat illustrates the electrical connections between the thermostat, the heating or cooling system, and the power supply. it shows the different wires and terminals involved in the system and their corresponding functions. the diagram provides a visual representation of how the thermostat interacts with the hvac. The thermostat uses one wire to control the primary functions of your hvac system, such as heating, cooling, and fan. see the diagram below for the role of each wire in your system: s – indoor and outdoor wired sensors y – compressor stage 1 (cooling) y2 – compressor stage 2 (cooling) g – fan c – common. Green wire: fan. white wire: heating. blue wire: cooling. rh: heating power. rc: cooling power. to reconnect the wire, simply put the wire on the right terminal and tighten down the set screw. pull a wire a bit to make sure the wire is properly fixed. example: reconnect the red wire to r, tighten the screw, check, and move to the new wire. The 5 wire thermostat wiring color code includes a red wire that works for power (24v), a white wire that works for heating, a green wire that works for fan, a yellow or sky blue wire that works for cooling, and a black wire that works as “common” or “c” wire. let’s tell you how to wire a 5 wire thermostat below:.
