On the market today, you will find a lot of heating and cooling options but one of the best is definitely the heat pump system. When most people obtain the heat pump system, one of the things that they usually want to understand is how to do the wiring. The system has many wires that may seem a little bit confusing. For the heat pump system to start working, you will need to hook up about eight to ten wires. You must do the wiring correctly if you want to system to work efficiently so that you can get the proper amount of heating as well as cooling.
The first thing you need to do before you start the wiring of the heat pump system is to turn off the electricity. The mains electricity should be turned off to make sure that none of the wires are carrying voltage. After that, you will need to identify the type of thermostat you are using. In case you are not sure about the type, you will need to check the number of wires that are sticking out of the panel. To access the wires, you will need to remove the thermostat and then you will see them attached to its back. A traditional heating device usually has less than five wires while a modern one will have five wires or more.
The next thing you will need to do is to determine the meaning of the wiring of your thermostat. At the back of the thermostat, there are wires of different colors. On the sides of the system at the bottom, you will see a series of letters which should each match with a different wire. For instance, letters marked as RC should connect to a red wire. Make sure that every wire is plugged correctly at the right place. Another connection that you will need to make sure that it is done correctly is the one with an RH and RC terminal. These two usually have a short wire that connects them.
You will need to connect the G terminal to the green wire. This one usually controls the blower that helps in cooling the system. Another terminal that you have to make sure that is connected properly is the Y terminal. This one is usually connected to the yellow section and the compressor. There is also a white wire that is usually connected to the W2 terminal. Just make sure that all instructions are followed properly for the heat pump system to work properly.
The last thing you will need to do is to install the heat pump thermostat wiring. Before you do that, look at the end of the wire. In order to see it properly, you may need to remove the insulation using a wire cutter or by simply peeling it off with a pair of pliers. You will need to unscrew the terminal while taking care not to remove the screw completely, and then push the wire into the space created. After that, tighten the screw and then do the same for all the other terminals that require a wire. Once you are done, replace the thermostat and then power on the electricity.
