• TH8110U1003 – Single-stage systems

All models have a similar process to install, but some differences based on the type of system appear.

Prior to the installation of the Honeywell 8000 Thermostat.

Items and Resources Necessary.

The availability of the right tools will save on time wastage during installations and errors in the wiring.

• flathead screwdrivers, Phillips and flathead screwdrivers.

• Drill and drill bits

• Wall anchors (included)

• Level

• Voltage tester

• Wire labels or masking tape

• Smartphone or camera (to use in case of wiring parameters photographs)

Safety (Very Important) Requirements

• Caution Do not start the installation until the circuit breaker to the HVAC system is turned off.
• Precaution In live thermostat wires, never work on live wires.
• Caution Do not connect the Honeywell 8000 to line-voltage (120 V or 240 V).

Lack of the safety precautions can result in electrical shock or breakage of HVAC control board.

HVAC System Compatibility

Honeywell 8000 is able to interface with the majority of low voltage systems including:

Supported Systems

• Gas furnaces

• Oil furnaces

• Electric furnaces

• Central air conditioners

• Up to 3 heat / 2 cool stages heat pump.

• Dual-fuel systems

Not Compatible With

• Millivolt systems

• Electric baseboard heaters

• High-voltage systems

C-Wire and the Importance of Power Requirements.

The Honeywell 8000 runs on 24 VAC power that is provided by the HVAC system.

Why the C-Wire Matters

• Gives constant presence of power to the thermostat.

• Required for Wi-Fi models

• Eliminates flickering of the screen and resetting the system.

In case there is no C-wire provided, this might require a professional HVAC technician to add a C-wire or a power adapter.

Step 1: The Dismantling of the current Thermostat.

Turn off power at the breaker.

Take out the faceplate of the thermostat.

Have a clear photograph of wiring that is there.

The terminal letters are labeled on each of the wires.

Unscrew the plate that is used in the mount and carefully poke wires through the wall.

💡 Do not allow wires to hang back in wall. Use tape to secure them.

At step 2, the Honeywell 8000 Wall Plate will be mounting.

• Detach the Honeywell 8000 wall plate and body thermostat.

• Pass wires through the center opening which is labeled as feed.

• Fix the plate wall at the level at the wall.

• Mark screw holes.

• Drilled holes and mounted wall anchors (where necessary).

• Use screws to hold the plate of the wall.

Preferred elevation of mounting: 1.5 meters (5 feet) of the floor and should not be near heat sources and drafts.

Step 3: 8000 Wiring Instructions (In Detail) – Honeywell.

The most important procedure during the installation process is correct wiring.

Standard Terminal Functions

Conventional System Wiring

• R → Power
• Y → Cooling
• W → Heating
• G → Fan
• C → Common

Heat Pump Wiring

O/B terminal has to be set properly.

AUX/E used for backup heat

Improper wiring may lead to cooling when the heating process occurs.

Caution Do not jump earth without being told to do so by system set-up.

Step 4: The displaying of the thermostat.

• Forcefully push additional wiring in the wall.

• Fit plate of thermostat to wall.

• Press hard until the hook is hardened.

• Power supply is restored in the circuit breaker.

Honeywell 8000 is expected to start up.

Step 5: Installer Set up menu (Critical Step)

The installer installation is to make the thermostat communicate with the HVAC system properly.

You can go through the steps of installer set up by following the instructions below.

• Press System

• Release the center blank button by pressing.

• Navigation through menu is done using arrow buttons.

Key Installer Configuration Options

Incorrect installer settings may cause:

• Short cycling
• System lockouts
• Poor temperature control

Step 6: Honeywell 8000 programming Honeywell 8000.

Scheduling Capabilities

• 7-day programmable schedule

• Up to 4 time periods per day

• Manual override mode

Daily Program Periods

• Wake

• Leave

Honeywell 8000 Wi-Fi Models Wi-Fi Set-Up.

Wi-Fi models can be fully controlled by the Honeywell Home app.

Wi-Fi Setup Steps

• Ensure C-wire is connected

• Installation with Wi-Fi network.

• Registering device in Honeywell Home portal.

• However, remotely control temperature.

• Get notifications and servicing messages.

Internet It should be operating on a stable internet connection.

Ordinary Error of Installation (And how to prevent it).

• Skipping installer setup

• Wrong O/B valve set up.

• Forgetting to connect C-wire

• Coloured wiring as opposed to labeled wiring.

• Installation of thermostat around heat sources.

These are some of the mistakes that should be avoided to guarantee long-term performance.
