Heat pump thermostat wiring - A typical wire color and terminal diagram. As shown in the diagram, you will need to power up the thermostat and the 24V AC power is connected to the R and C terminals. The color of wire R is usually RED and C is BLACK. C is known as the common terminal. These two connections will ensure that there is power to the thermostat that you are operating.
HOW TO DIAGNOSE AND CORRECT REVERSING VALVE PROBLEMSLet's begin by trying to gain an understanding of the reversing valve and its function. HOW A REVERSING VALVE WORKS . Heat pumps operate in one of two modes: with reversing valve and unit operating in the cooling phase when the solenoid coil is de-energized, or with valve and unit operating in the heating phase when the solenoid is de-energized.

Heat Pump Wiring DiagramsReversing Valve 1st Stage Heat (white) 2nd Stage Heat (brown) Low Voltage Connection Some AC Systems will have a blue wire with a pink stripe in place of the yellow or Y wire. 11 This diagram is to be used as reference for the low voltage control wiring of your heating and AC system. Always refer to your thermostat or equipment
44-way valve with operating control used for heat pumps. This is called the 4-way valve, because it has four connections refrigerant pipes. Because the heat pump uses of reversible mechanical refrigeration cycle, such device is not required.. Shown here, the heat pump cooling works like any cooling system when it is in cooling mode.
44-way reversing valves. This type of valve is used to completely reverse the flow in a reversible system. Such valves may be used when both heating and cooling modes are required, or to provide an effective, energy-efficient defrosting method. 4-Way Reversing Valves Construction A 4-way reversing valve has four ports for tube connections. Three ...
PowerPoint PresentationREVERSING VALVE-208 VAC from A and B phase activate the reversing valve in cooling mode-Power goes through TB2 pin 5 and 8-110 VAC toTP3 pin 8 through the fuse (Power into SSRs) -110 VAC through SSR K3 to TP3 Pin 7 -110 VAC to TB2 pin 8 to reversing valve-Use TP2 and reversing valve plug to isolate and troubleshoot
33some heat pumps use b rather than o for reversing valve. different heat pump models label the auxiliary heat terminal differently than shown. consult heat pump wiring guide. if lockout of aux heat on high outdoor temperature is required, wire c7089u1006 to the two “s” terminals. th6210u model cannot do aux heat lockout.
How to Wire a Carrier Heat Pump Thermostat | HunkerOrange wire to O. This controls the reversing valve that turns cooling pump into a heat pump. Blue wire to B. This also controls the reversing valve, switching back to the cooling function. ... It has a wiring diagram, but to use it, you'll have to verify that the wires follow the standard color code. You can also examine the old thermostat ...
Goodman heat pump wiring | Hvac Pro ForumsI'm assuming something to do with heating but why is it needed if the reversing valve is energized (or not?) 3 - why is it called W2? All the diagrams say to wire it to the W terminal of the AHU, and to the W terminal of the stat. I always thought of W2 as a 2nd heat stage but the system in question is single stage HP only.
