The thermostat that is used to control the heating and cooling HVAC system in your home is a low-voltage device that is easy enough to replace. And replacing one is a very common project, as homeowners swap out older thermostats requiring manual adjustment with newer programmable thermostats that change temperatures automatically at preset times. But people are often confused by the system by which the low voltage wires are labeled, which can look different in an old thermostat than it does in a new one. Contrary to popular belief, the letters do not correspond to wire colors but rather are used to indicate the various function signals controlled by each wire.

A lot of people are familiar with a thermostat simply because these things regulate the temperature either hot or cold of their appliances. Common appliances that have thermostat readings are refrigerators, air conditioning units, heaters, and other heating or cooling devices. Thermostats are quite crucial in keeping your appliances running, but are you familiar with the wires that make them work? The RH and the RC wires are found in every thermostat. If you need to change the wires, basic knowledge of them will be very helpful. In a heating or a cooling unit, a thermostat is powered by a heating system and a cooling system. These systems work together in order to regulate the desired temperature inside the unit. This means that the cooling system will automatically turn on when the temperature is going up. The same goes for the opposite. Yes, even your air conditioning unit has a heating system to keep the temperature in balance. To add to that, the wire is not always red. There is no standard for the color of the RH wire, but most units use a red one. For the RC, it powers the cooling system. The thermostat that you see on your air conditioning unit is wired to a furnace.

Here are some of the most common wires and what they signify.

They are used with HVAC systems with two separate transformers — one for cooling and one for heating. The RC terminal supplies the volt cooling power, and the RH terminal is the volt heating power supply. Many homeowners want to replace a faulty HVAC thermostat themselves but are not electricians or technically trained people. You will find that if your thermostat has an RC terminal it will have an RH terminal as well, and vice versa. The RC terminal passes power to the cooling circuit for the air conditioners in your home.

In certain homes or buildings, hybrid heating and cooling systems are installed to optimize temperature control and energy efficiency. These systems often require jumper wires between the Rc and Rh terminals in order to function properly. The purpose of these jumper wires is to connect the cooling and heating components of the system, allowing for seamless operation and accurate temperature regulation.

To ensure safe and accurate wiring, following the manufacturer's instructions, consulting professional guidance, or seeking assistance from an HVAC technician when working with thermostat wiring is always recommended. On many thermostats, heat pumps will use W as well often W2 - this activates aux heat, though Honeywell calls this terminal "Aux" instead. The placement of the R wire, also known as the power or volt wire, depends on the specific HVAC system and thermostat setup. So then Rc is common? How many wires does a Nest thermostat need? From Rc it heads out to Y and Y2 if there are 2 stages Is that right? The same goes for the opposite. Develop and improve services. However, there are factors to consider when determining the appropriate connection: 1.
