Honeywell thermostat wiring diagram 6 wire

Heat pump systems with a C-wire and advanced heating and AC require 6 or more wires. For example, a two stage heat pump, one with Aux heat and/or one that has a reversing valve that needs power all require 6 wire thermostat wiring or more (7 and 8 wiring follow).

What color wire goes where on a Honeywell thermostat?

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 Honeywell thermostat wire go?

The W wire is connected to your heating system. If your thermostat controls your heat, you will have a white wire. The Y wire is yellow and connects to your air conditioning compressor. The G wire is green and connects to the fan.

Do I need a jumper between R and RC? If you have one wire — even if it's labeled RC — it goes into the R terminal, setting the jumper connecting terminals R and RC in place. Thermostats may have a jumper switch, metal staple, or plug. The jumper may also be a wire connecting the two terminals.29 Aug 2022 How to Wire a Thermostat - Honeywell Home https://www.honeywellhome.com › ... › support article Search for: Do I need a jumper between R and RC?

What is the brown wire for on 6 wire thermostat?

If your thermostat doesn't have a separate connector labeled C and you're not sure what type of system you have: A brown wire is mostly likely a heat pump wire and should be connected to the O/B connector on the Nest thermostat. If the B wire is blue, it should most likely be connected to the C connector.

How do I use an old Honeywell thermostat?

If you have a manual thermostat, setting the temperature on your Honeywell thermostat is simple. All you need to do is to press the up and down buttons to set the temperature. The temperature you set will stay until you change the temperature again.

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.

Is RC the same as C wire?

The C and Rc wires are not the same. To install this thermostat you should follow the exact same wiring of the previous thermostat.

What color is the C wire?

Blue wires are also called “C” wires because they are the Common wire. C wires are necessary for any “smart” thermostat that needs to be connected to a power source 24/7, regardless of your heat pump type.

Is RC wire same as R?

R in general R , Rh , and Rc are all the same, but not. In general terms, the R terminal is where you connect the signal voltage source. In low voltage controlled systems, there will be a step down transformer that provides the power to the control circuitry.

Do I connect red wire to RC or RH?

The RH wire refers to “red heating” which means that this is the connection you need in order to power the heating system of your air conditioning unit. Yes, even your air conditioning unit has a heating system to keep the temperature in balance.

What is the difference between R and RC Honeywell thermostat?

If you have both an Rh and an Rc wire, the former powers the heating and the latter powers the cooling (using two separate transformers). If, for example, you have an R wire and an Rc wire, the R wire controls the heating system.

Where does brown wire go Honeywell?

A brown wire is run from the second heat source to this terminal. The terminal is used to power the Fan. A green wire is run from the Indoor Blower Fan to this terminal.

What is the brown wire on Honeywell thermostat?

Marking	Wire Color Code	Description
Rh	Red	Power from heat, 24 Vac transformer
C	Black/Blue	Common of 24 Vac transformer
W	White	Primary heat cell relay
E	Brown	Emergency heat relay

Is brown wire positive or negative?

Function	label	Color
Positive (of a negative earthed) circuit	L+	brown
Negative (of a negative earthed) circuit	M	blue
Positive (of a positive earthed) circuit	M	blue
Negative (of a positive earthed) circuit	L-	grey

How do I know what model Honeywell thermostat I have?

For most thermostats, the Model Number is located on the back of the detachable face plate. You can also find this on your product packaging, as well as included literature. If you're registering a warranty or rebate for a Wi-Fi product, use the MAC ID as your Serial Number.

Why is my Honeywell thermostat not turning on heat?

A Honeywell thermostat won't turn on the heat because of faulty sensors, improper installation, tripped circuit breakers, etc. The heat not turning on issue on your Honeywell thermostat may be fixed by resetting the Thermostat.

Why is my thermostat not turning the heat on?

If your heating system will not turn on, the first thing you should do is check the thermostat. The thermostat's battery may have gone bad, causing it to power off. If your thermostat is hardwired, a power surge, brownout, or brief power outage may have caused the thermostat to lose its settings.

Is the C wire hot?

Typically, the wires that provide the power (often called the “hot” wires) are labeled Rc (cooling) and Rh (heating).

Can you touch thermostat wires?

You can feel it, but it is not likely to cause a fatal shock. However, “messing” with any wires under power is a BAD idea. Some thermostats use low voltage from a control circuit and these are unlikely to give you a shock.
