Honeywell T6865H2WG-R Digital Thermostat, 24V, 3-Speed Fan Control (Blue Display)

The Honeywell T6865H2WG-R is a 24V digital thermostat designed to regulate central HVAC systems with precise temperature control and a three-speed fan function. It provides accurate sensing, a blue backlit display for easy reading, and a user-friendly interface to manage comfort and energy use in cooling and heating setups.

This model operates on 24V low-voltage controls and is suited for central air conditioning and HVAC automation that use 24V wiring. It’s designed for fan-coil type and similar low-voltage HVAC setups, ensuring reliable control without high-power connections.

The thermostat offers three fan-speed options that you can set automatically or manually. The Auto setting adjusts the fan speed based on cooling or heating needs, while the three fixed speed levels let you choose a preferred airflow that aligns with comfort and energy goals.

It features a blue backlit display for clear visibility in various lighting conditions. The interface is designed to be intuitive with clearly labeled controls and indicators, making setup and daily adjustments straightforward.

The thermostat provides precise temperature regulation and efficient fan control, which helps prevent unnecessary cooling or heating cycles. By maintaining stable temperatures and enabling optimized fan operation, it contributes to lower overall energy usage in compatible HVAC systems.

Power should be turned off at the circuit breaker before starting. Mount the thermostat in a standard wall box, and wire it to the 24V terminals (common arrangements include R, C, G, Y, W depending on your system). Always follow the wiring diagram included with the unit and consult a licensed HVAC technician if you’re unsure about wiring or compatibility with your specific system.

Use cases include managing comfort in homes with central air conditioning, HVAC automation projects, and systems that require reliable 24V low-voltage control with precise temperature and fan-speed regulation. It’s especially well-suited for installations where a blue-backlit display and a clean, modern interface are desired.

Yes. It is designed for standard 24V low-voltage HVAC wiring. Ensure you follow electrical safety guidelines, turn off power before installation, and install in a dry, indoor location. If the system involves complex wiring or heat pumps, verify compatibility or consult an HVAC professional.
