Hvac Thermostat Wiring Colors The thermostat wiring is a bit complicated. the 1st thing everybody has to learn is what each thermostat wire color means. to help you get started, we have prepared a full thermostat wiring color code (we’ll go wire by wire color by color for blue wire or black wire (c wires), orange wire, yellow wire, red wire, white wire, green wire, light blue hvac wire, and so on). These control the power, heat and fan. standard thermostats use 4 or 5 wires: r, w, g, y, and sometimes c. these control the power, heat, fan, and cooling. more advanced thermostats use 6 8 wires. the extra wires control additional hvac system features and settings, signaling a two stage cooling or heat pump system.
Common Thermostat Wiring Colors Here’s how to wire a thermostat using the color code and, fyi, each terminal’s purpose. attach the red wire to the r terminal (call for heating and or cooling). attach the green wire to the g terminal (fan). attach the white wire to the w terminal (heat). attach the yellow wire to the y terminal (ac). Thermostat terminal designations quick guide detail wiring color guide below. red wire connects to the r terminal with the red wire. rc wire connects to the rc terminal rc red. rh wire connects to rh terminal rh heat. y wire connects to the y terminal and is for cooling stage 1 with the yellow wire. Yellow wires. the yellow wires on your thermostat connect to your compressor. they control your air conditioning system by turning the compressor on and off. the yellow wires connect your thermostat to your compressor contactor via the air handler. the yellow wires connect to the y terminals on your thermostat. 6 wire thermostat wiring color code. you’ll have a 6 wire thermostat if your system has two stages of heat and one stage of air conditioning. two stage heating systems have a low setting and a high setting. apart from the red, green, white, yellow, and black or blue common wire, a 6 wire thermostat will also have a brown wire that connects to.

Red wire. the red wire can either r, rc or rh. let’s look at what each of these wires really is below. r: this is the power wire for the heating system. it carries 24 volt power from the transformer to the thermostat. rc: this is the power wire for cooling. some thermostats have separate rc and r terminals. in that case you will need to put a. Here are the most common thermostat wire color codes for heat pump systems: red (r): this wire connects to the power supply circuit. it provides the 24 volt power for the thermostat. green (g): the green wire controls the fan relay, which activates the blower fan to circulate air throughout the home.
