The HZ322 also features adjustable high and low limits, allowing for precise temperature control. The high limit is adjustable from 110°F to 180°F, while the low limit is adjustable from 30°F to 60°F. These limits help to ensure that the system operates within safe and efficient parameters. With its comprehensive specifications and compatibility with a wide range of accessories, the HZ322 offers a flexible and adaptable solution for zoning applications.
Mounting and Installation
The Honeywell HZ322 TrueZONE panel is designed for easy installation. It can be mounted in any orientation, but it is recommended to level it for aesthetic purposes. The mounting process involves separating the zone panel cover from the base and using the base as a template to drill mounting holes. The base is then attached to the wall, stud, or roof truss using screws. Two user-supplied screws can be used for center-line mounting on a 2×4, or four screws can be used at the corners for wall mounting. The HZ322 should be mounted near the HVAC equipment, ensuring easy access for wiring and maintenance.
The installation process includes connecting the necessary wires to the panel. The panel features color-coded terminals for easy identification. It is crucial to disconnect power before beginning the installation process to avoid electrical shock or equipment damage. The entire panel should be wired before applying transformer power. The wiring process varies depending on the type of system being installed. For conventional systems, specific instructions can be found on page 5 of the installation manual.
Wiring
The Honeywell HZ322 TrueZONE panel utilizes a straightforward wiring system, with color-coded terminals for ease of connection. Before starting the wiring process, it is crucial to disconnect power to the system to prevent electrical shock or equipment damage. The entire panel should be wired completely before applying power from the transformer. The wiring procedure may differ slightly depending on the specific system being installed. For conventional systems, detailed instructions are provided on page 5 of the installation manual.
The HZ322 panel is compatible with a variety of HVAC components. It can be used with conventional gas, oil, or electric forced-air systems, supporting up to two stages of heating and cooling. It also supports heat pump systems with a single-stage compressor and auxiliary heat. The panel can manage up to three forced-air zones using wired thermostats. For wireless thermostat operation, an optional wireless adapter is required.
For variable-speed fans, the DS/BK terminal on the HZ322 panel should be connected to the DS, BK, ODD, or DHUM terminal on the HVAC equipment. This terminal energizes when two or three zones are calling for cooling, resulting in the blower fan operating at its normal speed.
Connecting Wireless Devices
The Honeywell HZ322 TrueZONE panel offers the flexibility to connect wireless thermostats for enhanced convenience and control. To enable wireless operation, a separate wireless adapter, the THM4000R1000, is required. This adapter acts as a bridge between the zone panel and the wireless thermostats, facilitating seamless communication.
The integration of wireless thermostats allows homeowners to adjust the temperature in each zone remotely, eliminating the need to manually access the zone panel. These thermostats provide real-time temperature readings and allow for personalized comfort settings for each zone. The wireless connectivity also empowers users to monitor and manage their HVAC system remotely, optimizing energy efficiency and comfort.
When selecting wireless thermostats, it’s important to ensure compatibility with the HZ322 panel. The recommended thermostats for use with the HZ322 are listed in the installation manual. These thermostats are specifically designed to work seamlessly with the panel’s features and functionality, providing a smooth and reliable wireless experience.
