Honeywell TH6320ZW2003 – T6 Pro Z-Wave Programmable Thermostat

Upgrade HVAC control with the Honeywell TH6320ZW2003 T6 Pro Z-Wave Programmable Thermostat , a versatile wall-mounted controller designed to integrate with Z-Wave compatible controllers and gateways. Supporting up to 3-stage heating / 2-stage cooling heat pump systems or 2-stage heating / 2-stage cooling conventional systems , it combines flexible HVAC control, programmable scheduling, Z-Wave Plus connectivity, and a clean residential-style interface.

Flexible HVAC System Control

The TH6320ZW2003 is designed for a wide range of HVAC applications, supporting up to 3H/2C heat pump systems and up to 2H/2C conventional systems . It also supports dual-fuel applications and auxiliary heat lockout when used with an outdoor sensor , providing additional flexibility for heat pump installations.

Z-Wave Plus Connectivity

Designed to work with Z-Wave compliant controllers and gateways , the TH6320ZW2003 allows thermostat operation to be integrated into compatible connected-home platforms. A security-enabled Z-Wave Plus controller is recommended to take full advantage of thermostat functionality. Z-Wave Plus provides improved interoperability, range, battery life, and bandwidth compared with earlier Z-Wave technology.

Flexible Programmable Scheduling

Customize comfort around the building's schedule with multiple programming options. The thermostat supports 7-day, 5-1-1, 5-2, and non-programmable configurations , as well as occupancy-controlled operation through compatible Z-Wave panel or app integration.

Heating & Cooling Control

The thermostat provides dedicated heating and cooling setpoint ranges and clearly indicates system operation by displaying "Heat On" or "Cool On" when the respective equipment is running. Heating can be adjusted from 40°F to 90°F , while cooling can be set from 50°F to 99°F .

Reliable Temperature Sensing

Built-in temperature sensing provides accuracy of ±1.5°F at 70°F , helping the thermostat maintain consistent indoor comfort. Selectable maximum heating and minimum cooling range stops and a keypad lockout provide additional control over thermostat adjustments.

Battery or C-Wire Power Options

The TH6320ZW2003 offers flexible power options for different installation requirements. It can operate using three AA alkaline batteries and/or an 18–30VAC C-wire connection , making it adaptable to both existing thermostat replacements and new installations.

Simple Wall-Mount Installation

The thermostat includes a UWP mounting system that installs directly to the wall using the provided mounting screws and anchors. A cover plate is also provided to help conceal marks left behind by a previously installed thermostat. Its compact white enclosure measures approximately 4-1/16"H x 4-1/16"W x 1-5/32"D .

Advanced Z-Wave Integration

The thermostat operates at 908.42 MHz in the U.S. and Canada and is Z-Wave Plus certified. Supported functionality includes thermostat mode, setpoint, fan mode, fan state, operating state, battery reporting, notifications, and multilevel sensor communication. It also supports secure Z-Wave communication.

Home & Away Comfort Control

Through Z-Wave integration, the thermostat supports energy-saving Away and Comfort/Home states , allowing a compatible automation platform to switch between reduced-energy and normal comfort settings. This makes the thermostat well suited for connected residential and light commercial HVAC applications.
