Heating and cooling thermostat wiring diagram.

Red wire for rc terminal. In this case the power from the transformer in the air conditioning system would go to the thermostat terminal. In depth thermostat wiring guide for homeowners nest thermostat wiring diagram for 2 stage cooling 2 stage heat nest thermostat itself is another generation of cooling and heating apparatus. The rh wire connects to the heating system.

S indoor and outdoor wired sensors. A transformer for cooling and a transformer for heating. This wire connects to your heat pump if applicable. A wiring diagram is a streamlined traditional pictorial representation of an electric circuit.

See the diagram below for what each wire controls on your system. Not only does it allow you to control temperature readily but the device can also be able to find out your own pattern. Air conditioning ac contactor control board 1 this diagram is to be used as reference for the low voltage control wiring of your heating and ac system. It reveals the components of the circuit as streamlined shapes as well as the power as well as signal connections in between the devices.

The rc wire connects to the cooling system. By the use of an adjustable set point the job of the thermostat is to turn on either the heating or cooling system to maintain the desired room temperature in the home and to turn off the system when the desired temperature is achieved. Note some ac systems will have a blue wire with a pink stripe in place of the yellow or y wire. The blue wire on the thermostat is the common or c wire.

Furthermore it should be noted that a jumper can be installed between rc and rh for a heating and cooling system equipped with a single transformer. This wire may be red without an h attached in some cases. The thermostat uses 1 wire to control each of your hvac system s primary functions such as heating cooling fan etc. Instead c wires help deliver power from the system to the thermostat in case the other wires can t provide enough power.

Always refer to your thermostat or equipment installation guides to verify proper wiring. The common c wire doesn t control heating or cooling. The thermostat is the control device that provides a simple user interface with the internal workings of your homes climate control system. Not all systems have a c wire installed but nest thermostats were engineered to use as little power as possible for their display and internal circuitry so in the.
