Where does white wire go on heat pump thermostat?

5 wire thermostats are the most versatile thermostat; they control anything from smart air conditioners, heat pumps, furnaces, and so on. Here are the 5 wire colors and terminals codes: Red wire for power (24V). White wire for heating (connected to W or W1 terminal).

What color wire goes where on a thermostat?

Most thermostats have a Red wire that is the power wire that usually connects to R & RC terminals of the thermostat, a Green wire that energizes the Fan relay, connected to the “G” terminal on the thermostat, a Yellow wire that energizes the outdoor unit’s contactor, (if you have air conditioning) and a white wire that …

What do the colors on thermostat wires mean?

Rh stands for Red-Heat and Rc stands for Red-Cool. If you only have a single red wire the jumper between Rh and Rc are required for some heating and cooling hybrid systems depending on your thermostat. Yellow/Y is the AC compressor. White/W is the Heating element. Green/G runs the fan.

What is the color code for a thermostat?

This is the most typical thermostat wiring style, and it applies to systems that regulate both heat and air conditioning. The wires are typically arranged as follows: red for 24-volt hot, white for heat, yellow for cooling, green for the fan, and blue for common (although the common wire may be a different color).

Where does the red wire go on a thermostat?

The red wire should be connected with the Thermostat RH terminal. You can also connect it to the RC terminal with a jumper wire between the RH and the RC. If you only have one R terminal for both heating and cooling, connect it to that.

Does your heat pump use an O wire or B wire?

The O and B terminals are for heat pumps; the B terminal is used in conjunction with Rheem, Ruud, or any other manufacturer that energizes the reversing valve in the heat pump’s heating mode.

What happens if you wire a thermostat wrong?

Potential consequences of improper installation could include: Electric shock. Blowing a circuit breaker. Damaging the thermostat unit, the electrical system or even the AC/furnace unit itself.

Where does the red wire go on my thermostat?

What is the common wire in a 3 way switch?

Black wire
Black wire: This is a hot wire that carries electricity from the power source to the first switch in a typical 3-way setup. It’s also called the “common wire” or the “line wire.” Unless the breaker is off, this black wire is always hot.

Does R go to RC or RH?

In a thermostat, the R wire is responsible for powering the entire HVAC system (through a transformer). If you have both an Rh (Red-heat for powering the heating) and an Rc (Red-cool for powering the cooling), then the R wire can be connected to either Rh or Rc.

What color is a heat pump wire?

The Blue or “C” Wire C wires or varying colors apply to every thermostat, but blue C wires belong to thermostats attached to a heat pump. Blue wires are for heat pumps, like orange wires.

Can I use a Nest thermostat with only 2 wires?

The Nest Thermostat is compatible with 2 wire low voltage HVAC systems that are either heat only systems or cooling only systems.

What color is the common wire in a thermostat?

The common wire is usually blue or black, but that is not guaranteed. The previous homeowner may have made the wires whatever color they wanted or they could have run any wire they had available, so never rely on color alone. Regardless of color, the common wire is connected to the C port inside your thermostat.

What color wires go where on a thermostat?

Thermostat Wire. Thermostat wire comes in a bundle with the outer jacket of the thermostat wire being either brown or white. The bundle can have anywhere from 2 conductors inside the bundle or outer jacket and all the way up 8 or 10 conductors inside the outer brown or white jacket.

How do you wire a heat pump?

Insert the high voltage wire through the hole on the side of the heat pump unit which is called a electrical knockout. Once wires are through the knockout use a electrical connector to secure them. High voltage wire should be sized from manufacturer’s recommendation for heat pump’s size and length of wire.

What do thermostat wiring colors mean?

So, this is what you might expect to see in terms of colored wires and what they mean: White – The white wire is what connects to the (auxiliary) heat on your system. Yellow – The yellow wire connects to your compressor. Green – The green wire connects to the fan. Orange – This wire connects to your heat pump (if you have one). Red – Now, there can be two separate wires for this. Blue – This is your common or “C” wire.
