How do I install a Honeywell thermostat?

If the Honeywell thermostat installation is to control an air conditioning system, youll have an R wire for power and a W wire to control the air conditioner. You may also have a Y wire (yellow) to control the compressor motor. Attach this to the Y terminal. If the heating/cooling system includes a heat pump, youll find at least one extra wire.

How to connect a heat pump to a thermostat?

This ensures the system heats in the heat mode and cools in the cool mode. When the thermostat controls a heat pump, both the Y and W terminals are used, but you may have only one of these wires. In that case, install a jumper wire between the Y and W terminals to connect them and attach the wire you have to the appropriate terminal.

How do I know if my thermostat has a heat pump?

If you have separate wires for O and B, you will want to tape off the B wire so it can’t make contact, and the O wire will be connected to the O/B terminal on your thermostat. If your O or B terminal shares a label with another wire, typically W, you’ll need to identify whether you have a heat pump system or not.

What is the HG wire on a Honeywell thermostat?

Leave it in the HG position for a gas or oil furnace. If the Honeywell thermostat installation is to control an air conditioning system, youll have an R wire for power and a W wire to control the air conditioner. You may also have a Y wire (yellow) to control the compressor motor.

Where do the wires go on a new thermostat?

If you have a C wire, place it into the C terminal on your wall plate. Lets take a look at the G wire. This wire will go to the G terminal on your new thermostat. For the Y, Y1, and Y2 wires, Y or Y1 will go to the Y terminal, and Y2 will go to the Y2 terminal. The O/B wire can have many configurations.

What to do when you get a new Honeywell thermostat?

Get your new Honeywell Thermostat Now with everything removed – take a look at the new thermostat and base plate., along with the instructions, warnings, drywall anchors, screws, and labels. The labels are used to label your wires before removing them for future reference. Pro Tip: some thermostats – like the Honeywell – do not come with batteries.

How do you mount a thermostat to the wall?

The only trick that I have in my setup is that the “y” terminal would usually be yellow actually goes to my blue wire. Do a pull test to make sure all those wires are secure. Then, mount the thermostat onto the base plate or the wall plate – and it’ll pop into place.

What is the best Honeywell thermostat for home use?

The 9000 series is one of the most comprehensive thermostats in the Honeywell catalog. The WI-FI enabled device has a bigger touchscreen that gives you quick accessibility when reset or changing the settings. The 9000 series is a step up in technology.

What does each wire do on a Honeywell thermostat?

Each wire connects to a terminal that controls different variables of the heating and/or air conditioning system. Honeywell thermostats normally have four colored wires in their configuration. This wire connects the thermostat to the transformer that controls both the heating and cooling functions.

How do I identify a terminal on a Honeywell thermostat?

Your new Honeywell thermostat should be able to accommodate the same number of wires. Honeywell thermostats follow the industry standard for terminal identification. Each terminal is marked with a letter that usually corresponds to the color of the wire that should be used to connect it.

What wire do I use to hook up a thermostat?

If your system has both heating and cooling functions, youll need to connect both the Rc and Rh terminals with a red wire. Because many thermostats come with a pre-installed thermostat jumper wire that connects these terminals, you only need one red wire, which could be the thermostat Rc wire or the Rh wire.

What is a C wire on a thermostat?

A common wire (C-Wire) provides Wi-Fi thermostats continuous power by connecting it to a heating and cooling system (e.g. furnace). C-Wires are required on most Honeywell Wi-Fi thermostats, with the exception of the Smart Round Thermostat (formerly known as the Lyric Round).
