Resideo - Honeywell Home HZ322 Zone Control Panel

The HZ322 Zone Control Panel from Honeywell Home (Resideo) is a reliable zoning controller designed for precise comfort in multi-zone homes. This 3-zone panel supports a 2-heat/1-cool stage configuration, making it ideal for conventional 1-stage zoning heat pumps.

It performs over a wide temperature range from -40 to 165 degrees Fahrenheit and handles 5–90 percent relative humidity (non-condensing). The panel includes essential features such as LED indicators, Auto Changeover, a Discharge Air Temperature Sensor, a Resettable Fuse, and Zone Fan Control to optimize comfort and energy efficiency.
