Installation Guide
This section details the FocusPRO 5000 installation process, covering wallplate mounting, power options (battery or hardwired), and specific wiring configurations for various systems.
Follow these steps carefully to ensure proper functionality and optimal performance of your new Honeywell thermostat.
Wallplate Installation
Proper wallplate installation is crucial for a secure and functional Honeywell FocusPRO 5000 thermostat. Begin by turning off power to your heating and cooling system at the breaker to avoid electrical shock. Carefully remove your old thermostat, noting the wire connections for later reference.
Using the included screws, mount the new FocusPRO 5000 wallplate to the wall, ensuring it’s level. If existing holes don’t align, you may need to drill new ones, utilizing the provided anchors if necessary.
Gently feed the thermostat wires through the opening in the wallplate. Double-check that the wires are not pinched or damaged during this process. The wallplate serves as the base for connecting the thermostat to your system’s wiring, so a secure and neat installation is paramount. Refer to the wiring diagrams for your specific system type.
Important: Before proceeding, verify the wallplate is firmly attached and level.
Power Options: Battery and Hardwired
The Honeywell FocusPRO 5000 thermostat offers flexible power options: battery power or hardwired connection to your home’s electrical system. For battery operation, install two AA alkaline batteries into the designated compartment, observing the correct polarity. Battery power is ideal for systems without a common (C) wire.

However, for optimal performance and to avoid battery replacements, a hardwired connection is recommended. If a common (C) wire is available, connect it to the ‘C’ terminal on the thermostat’s wallplate. This provides continuous power, enabling all thermostat features.
Caution: Always disconnect power at the breaker before working with wiring.
Wiring Conventional Systems (1 Heat/1 Cool)
Wiring a Honeywell FocusPRO 5000 thermostat to a conventional 1 heat/1 cool system requires careful attention to terminal connections. First, ensure power is OFF at the breaker. Identify the wires from your existing thermostat – typically labeled R, W, Y, and G.
Connect the R wire (power) to the ‘Rh’ or ‘Rc’ terminal on the wallplate. The W wire (heat) connects to the ‘W’ terminal, and the Y wire (cool) connects to the ‘Y’ terminal. The G wire (fan) connects to the ‘G’ terminal. If you have a common (C) wire, connect it to the ‘C’ terminal for consistent power.
Important: If ‘Rh’ and ‘Rc’ are jumpered, leave them connected. If separate, connect ‘R’ to the terminal with power present when the system is off. Double-check all connections before restoring power. Incorrect wiring can damage your system.
Caution: If unsure, consult a qualified HVAC technician.
Wiring Heat Pump Systems
Wiring a Honeywell FocusPRO 5000 to a heat pump system differs from conventional systems, requiring attention to specific terminals. Begin by switching off power at the breaker. Identify wires typically labeled R, Y, W, G, and potentially O/B.
Connect the R wire to ‘Rh’ or ‘Rc’. The Y wire (compressor) connects to ‘Y’. The W wire, for auxiliary/emergency heat, connects to ‘W’. The G wire (fan) connects to ‘G’. For reversing valve control, the O or B wire connects to either ‘O’ or ‘B’ – consult your heat pump’s documentation to determine the correct terminal.
Warning: Incorrect wiring can cause system malfunction. Seek professional help if needed.
Thermostat Mounting to Wallplate
After completing the wiring, carefully align the Honeywell FocusPRO 5000 thermostat with the installed wallplate; Gently push the thermostat onto the wallplate, ensuring all wires are tucked neatly inside the wall opening to avoid pinching or damage.
You should hear or feel a click as the thermostat securely locks into place. If it doesn’t latch easily, double-check the wire connections and alignment. Do not force it! Once mounted, verify the thermostat is firmly attached and doesn’t wobble.

Restore power at the breaker. The thermostat display should illuminate. If it doesn’t, re-examine the wiring and power source. Finally, install the cover plate assembly, ensuring it’s properly seated.
Caution: Improper mounting can lead to loose connections and inaccurate readings.

Operation and Settings
The Honeywell FocusPRO 5000 allows easy temperature adjustments and offers special functions for customized comfort. Explore its intuitive interface for optimal control.
Users can readily set desired temperatures and utilize various modes to enhance energy efficiency and personalize their heating and cooling experience.
Setting the Temperature
Adjusting the temperature with your Honeywell FocusPRO 5000 thermostat is straightforward. The large, easy-to-read display prominently shows both the room temperature and your set temperature, ensuring clear visibility.
To raise the desired temperature, press the “Up” button; to lower it, press the “Down” button. Each press typically adjusts the temperature in one-degree increments. The thermostat will then activate your heating or cooling system to reach and maintain the selected temperature.
The current set temperature is continuously displayed, allowing you to monitor and adjust as needed. The system responds quickly to changes, providing consistent comfort. Remember that the thermostat operates based on the programmed system type (heat, cool, or auto), so ensure the correct mode is selected for optimal performance.
For precise control, observe the room temperature after each adjustment to achieve your preferred comfort level.
Special Functions and Modes
The Honeywell FocusPRO 5000 thermostat offers several useful functions beyond basic temperature control. While non-programmable, it provides operational modes to suit various needs.
The system mode selector allows you to choose between “Heat,” “Cool,” and “Auto” operations. In “Auto” mode, the thermostat intelligently switches between heating and cooling to maintain your set temperature. A fan control allows selection between “Auto” (fan runs only during heating/cooling) and “On” (continuous fan operation).
The thermostat also features a temporary override function. Briefly pressing the “Up” or “Down” buttons allows for a temporary temperature adjustment, reverting to the setpoint after a period.
