Honeywell Thermostat Wiring

Topic [Show]

Honeywell Thermostat Wiring. Color wire controls every operation is uncommon. Each wire should be known once the wire is wired by which terminal(s), ne'er by colour.

When you don't understand the terminal with which every wire connects, the HVAC system and the appearance on the panel names will be needed. Please consult your owners/install guide for typical cabling examples and clarifying the types of systems your thermostat uses.

The thermostat controls all of the main functions of your HVAC system, including heating, cooling, ventilation, and so on. For what every cable controls your system, see the diagram below:

S – Wired sensors both indoor and outdoor.
Y – Stage One mechanical equipment (Cooling).
Y2 – mechanical apparatus Set up a couple (Cooling).
G – Fan.
C – Joint.
U – Management of moisturizers, dehumidifiers, or fans.
L/A – A – warmth pump input defect.
O/B – Valve for reverse valve heating systems.
E – Heat for emergencies.
Aux/W2 – a couple of Heat Stages (Heating).
W – one heat phase (Heating).
TRY – VAC 24 (Heating transformer).
24vac RC – RC (Cooling transformer).

Trade model thermo-station area system (systems that use primary one or two stages of heating equipment and use gas or fire for back-up/emergency heating) for control of dual-fuel systems.

It is advised to simply contact an HVAC expert contractor to continue if you have a dual-fuel system and a zone unit not sure.

For fundamental wiring advances please follow the following guide:

To protect your equipment, close the facility on your heating and cooling equipment's breaker box or switch.

Modify the temperature in your existing thermostat so your system starts heating or cooling to ensure your system is off.

The facility is off if you do not hear or feel that the system is activated in 5 minutes.

You can save this step if you have a digit.

Next, remove your current plate thermostat. The majority of thermostats pull off the wall directly.

But some raise from the lowest and take off, and others have a protection tab.

A picture of your wiring is needed for the next step.

Please ensure that the area marking unit of the terminal is clearly visible once you have photographed it.

Check the photos.

When your new thermostat shows an AB C or a few of the three terminals, your system may not be directly compatible with the thermostatic communication thermostat.

You have a line voltage system if you are watching thick, black or red wires.

Such cabling requires a thermostat voltage line and is not compatible with low voltage thermostats.

You'll want a thermostat that can handle multi-fan speeds and not one of the retail thermostat areas compatible with that kind of method, if you see wires connected to the terminals labelled G1, G2, G3. G is not G1, G2, and/or G3 compatible, but G1.

Eighteen - solid core wires are what you should usually see. 5 drills, but you will see as few as 2, and as many as 10, are the most common configuration.

Any wire that is a donation that you do not want to make a note of but you will not mark these wires with the terminal.

Take every wire one after the other and label it by using the photos you simply took.

If a terminal has several designations, such as W and O/B, it will be labelled with W and O/B rather than one or the other.

You will be able to unscrew the recent thermostat plate and mount the new thermostatic plate after having removed all the wires and labelling them.

We will re-connect the wiring after mounting the new thermostat plate.

If we tend to suggest that a wire is placed during a terminal, please do not move it to another terminal if we tend to put it in the guide later.

(Ex. - you have one W-O/B label and we advise you to put it in the O/B terminal.

If you don't move this wire later in the guide you tend to suggest that we shoot the wire in W terminals, as we've taught you to put this wire in O/B.

Let's now configure cowl wiring.

Identify the R, RH or RC wires. Out of these 3, you will usually have one or two. If you have only one wire, no matter what RC it is, the R terminal will be entered and the connection terminals R and RC jumpers will be on the spot.

Some thermostats are equipped with a jumper, some with a metal staple, others with a plug and therefore the jumper can just be a wire that connects both terminals.

If you have 2 wires, the R or RH terminal could be entered and the RC terminal could be entered.

You can take any jumpers between R and Rc terminals or push it to open the terminal of RC so that you can insert a wire if you have quite one wire (for example, you have a ring labelled R and a wire label labelled Rc).

Let's take the C or common wire up next. Next...

You can verify your thermostat handbook with a trane model and a wire labelled X or B.

In some cases, you also have one of these wires. When you have a C-wire, put it on your plate in the C terminal.

Take a look at the wire of G. On your new thermostat, this wire may visit the G terminal.

Y, Y1, and Y2 cables may have visits to Y, Y, Y1, Y2 cables, Y2 cables and Y2 cables.

The O/B wire has multiple setups. They often include W-O/B, O/B, W-O, W-B, or you might even have different wires O and B.

If you have separate wires for O and B, you'll want to tap the B wire, so that you can not create contact and therefore the O wire on your thermostat is connected with the O/B terminal.

If your terminal O or B has a label on a different wire, usually W, then either you have a device system or you don't have it.

For every heating and cooling, an apparatus runs your mechanical device.

Put this wire in the W terminal if you don't understand your system sort.

Place it in the O/B terminal if you have an appliance system.

Find all wire labels W or W1 unconnected.

If you know of O, B or O/B cables that connect to the O/B terminal in the preceding stage and have a separate W-wire, place the cables in the W2 terminal.

Connect the W wire to the W terminal if you do not have a wire link to the O / B terminal.

What is C wire? Do I need one? What if don't have a c wire

What is a C Wire?

Wi-Fi Thermostats can be connected to a system of heating and refrigeration with a common wire (C-Wire) (e.g. furnace).

Area unit C-Wires is necessary on most Honeywell Wi-Fi heaters, except for the good thermostat (formerly referred to as the Lyric Round).

The area unit required for all WLAN thermostats from the Honeywell / Resideo area. For full wiring support/designations/functions for terminals.

How do I check whether the C Wire is used by my thermostat?

1. Put the skill down. To protect your equipment, put out the ability to control the chamber or heating equipment at the breaker box.

Note: If you turn off your thermostat, your chamber or heating equipment will not be put off.

2. Confirm that your system has been off. Modify your existing thermostat temperature so that your system starts to heat or cool. If in five minutes you don't hear or feel that the system works, the ability is off.

Note: If you have a blank show digital thermostat, skip this step.

3. Remove from the plate your current thermostat. You can start your thermostat with grabbing and gentle pulling on most thermostats. There may be thermostats with screws, buttons, and clasps.

Note: Do not take any thermostat wires at this time.

4. Have you a C Wire? Look at the current wall plate:
does the C-Terminal have a wire?
YES, this indicates that you use a C-Wire in your thermostat.

NO – this suggests you don't use the C-Wire thermostat. Please read the following questions to tell them what to try if a C-wire is missing from your thermostat.

Unused C-Wire Check

Some homes have an unused C-Wire inside the wall. To review unused C-Wire for associate degree:

1. Put off the power. Put off power Put the ability on the breaker box or switch to control the heating and cooling instrument to protect your device.

Note: The switch off from the thermostat does not postpone the instrumentation capacity.

2. Confirm that your system has been off. Modify your existing thermostat temperature so that your system starts to heat or cool. If in five minutes you don't hear or feel that the system works, the ability is off.

Note: If you have a blank show digital thermostat, skip this step.

3. Remove your existing plate thermostat. You can start your thermostat with grabbing and gentle pulling on most thermostats. There may be thermostats with screws, buttons, and clasps.

Note: Do not take any thermostat wires at this time.

4. Does a line voltage system have one? Line Voltage Systems have wire-loony or high-voltage marked black wires (120V or higher).

YES, – May is not compatible with your system. To find a pro-installer in your room, contact support at 1-855-733-5465.

5. Take a picture of the wiring of your existing wall plate. Ensure that all terminals are read honestly. Later this image you ought to reference.

6. Remove jumpers. There are two terminals used by a jumper. A little staple or colored wire should appear.
Note: don't throw out jumpers.

7. Mark cable. Label each wire with the stickers given to your new thermostat on your existing platform. You can use tape and a pen if you don't have stickers.
Remark: don't mark jumpers.

8. Specify the cables' colors. Check the boxes and type down in the existing plate the color of the cables that are connected to the terminals. Check for everything (not all can apply).

Note: You'll want further wiring support if there are wired terminals not listed in them. Click on 1-855-733-5465 to contact support.

9. Remove the current plate and unplug the wires. Some of them are "push-in" (slowly progresses to release the wire), and some are flathead. Some wire terminals are "push-in" You're going to want a vibrator to unleash terminal wires.

Note: Wrap the wires around a crayon so that they do not fall into the wall.

10. Have you a C-Wire? This checks whether your system does not use a C-Wire. Check the Step 8 thermostat cable list: This is controlled by the C-Terminal? Or else, you can check the Step 5 image cross-check: In the C-Terminal is there a wire?

YES – this suggests that your thermostat is using a C-Wire and that a C-Wire adapter should not be installed. In your new thermostat, you can continue to put it.

NO – this suggests you don't use the C-Wire thermostat. The next step still.

11. Is a partitioning panel available? Usually, you mount your partitioning panel to your chamber. It usually contains a bundle of wires running on your heating/cooling and smaller bundles of wires running on your duct.

YES – For zoned systems, it is extra difficult to install C-Wire Adapters. To find a pro-installer in your room, contact support at 1-855-733-5465.

12. Does one have unused wire for an associate degree? You removed your existing plate previously. Check the bundle of cables coming back from the wall.

Note: The bundle of wires should be pulled out of the wall to find the unused wire.
YES – this unused C-Wire can be used by you. NO – You don't want to use a C-Wire Adapter, because you do not have C-Wire. C-Wire Adapter sec employment still

13. Unused wire marking. Mark your unused wire as your new thermostat with the "C" sticker. You can use tape and a pen if you don't have stickers. To reveal at least 1/4 in. wire you ought to use a wire stripper.

Note: If several unused wires have been created, simply label one wire and create a color note.

14. Take the chamber or heat cowl away. To search for the control panel, open the heating and cooling system cowl. Also on the top or rock bottom is the control panel. A terminal label that ar is equivalent on your thermostat must be seen.

Note: Your system may not be compatible if you do not see an impact board. To search for pro-installer contact support at 1-855-733-5465.

15. Notice the unused wire's opposite finish. In Step 12, you found your existing thermostat with a bundle of wires. Find your chamber near or heat, then notice your unused wire, the opposite finish of this bundle.

Note: The unused wire should have the same color as your existing thermostat. For the color, you wrote down, see Step thirteen.

16. In the control panel, connect the unused wire to the C-terminal. Note: If cables within the C-terminal exist, ensure that they are still connected once the unused cables are connected.
