This central controller orchestrates the complex communication between up to three independent thermostats and your central heating and cooling equipment. Designed for both conventional systems (up to 2 Heat\/2 Cool) and Heat Pump applications (2 Heat\/1 Cool), the HZ322\/U ensures that airflow is precisely directed only to the areas of the home calling for conditioning. By managing damper positions and equipment staging, it optimizes comfort while significantly reducing energy waste in unoccupied rooms. \u003c\/p\u003e\n\u003ch2\u003eKey Features and Function:\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision Multi-Zone Management:\u003c\/strong\u003e Independently controls up to 3 separate zones, ensuring tailored comfort levels across different floors or wings of a home.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGenuine OEM TrueZone™ Reliability:\u003c\/strong\u003e Features Honeywell’s industry-leading robust construction with a digital display that simplifies setup and provides real-time system status.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvanced Safety \u0026amp; Equipment Protection:\u003c\/strong\u003e Includes a built-in Discharge Air Temperature (DATS) sensor logic to prevent coil freeze-ups or heat exchanger overheating during low-airflow conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlug-and-Play Wiring:\u003c\/strong\u003e Utilizes push-terminals for tool-free wiring and a common-sense layout that reduces installation time and eliminates wiring errors. \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eProduct Details and Key Specifications:\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e HZ322\/U (Replaces HZ322)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Honeywell Home \/ Resideo (Genuine OEM)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e 3-Zone Forced Air Zone Control Panel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\/SKU:\u003c\/strong\u003e 085267297967 \/ HZ322U\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 24 VAC, 60 Hz (Requires 40VA or 75VA Transformer)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Conventional (2H\/2C) or Heat Pump (2H\/1C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhase \/ Hertz:\u003c\/strong\u003e Single-phase (1PH) \/ 60 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Surface mount or snap-track compatible\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShipping Weight:\u003c\/strong\u003e 3.5 lbs \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e🛠️ HVAC Depot Pro Tip: Check the Transformer VA\u003c\/h2\u003e\n\u003cp\u003eWhen installing the HZ322\/U, always calculate the total VA draw of your dampers and thermostats. A standard 40VA transformer may be insufficient if you are running multiple power-open\/power-close dampers; in these cases, upgrading to a \u003cstrong\u003e75VA transformer\u003c\/strong\u003e prevents the panel from \"brown-out\" resets during heavy demand. Also, always install the DATS (Discharge Air Temperature Sensor) to ensure the panel can safely stage down equipment if a single small zone is the only one calling for air. \u003c\/p\u003e\n\u003ch2\u003eCross-Reference \u0026amp; Compatibility:\u003c\/h2\u003e\n\u003cp\u003eThe HZ322\/U is a direct OEM replacement or upgrade for the following part numbers:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Numbers:\u003c\/strong\u003e HZ322, HZ311 (Upgrade), MM-2, MM-3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLegacy Honeywell:\u003c\/strong\u003e TZ-3, TZ-4 (Check wiring compatibility)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":52451502752107,"sku":"HZ322","price":195.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0922\/9683\/9531\/files\/original_f8f90b06-c08b-4808-8dfb-4abb33c713be.png?v=1760124244","url":"https:\/\/tophvacparts.com\/products\/honeywell-damper-control-panel-hz322-3-zone-conventional-heat-pump","provider":"HVAC Parts and Equipment Depot Open To Homeowners and Contractors","version":"1.0","type":"link"}
