Zoning Made Effortless
If you've ever installed a zoning system by setting manual dip switches, you'll appreciate the convenience and time savings of Honeywell TrueZONET panels. Patented, digital installer setup and push terminals for wiring means no screwdriver is required. Plus, TrueZONE's standardized checkout  process helps eliminate callbacks by ensuring that the system is operating properly before the installer leaves the jobsite. It all adds up to true comfort for your customers and true profit for your bottom line.

Intuitive Installer Setup - Easy-to-follow, digital display uses real language to guide installer through four simple steps. (HZ432 and HZ322 only)
1) Select equipment type
2) Select heat/cool stages
3) Select number of zones
4) Select stage control

Standardized Checkout Procedure - Standardizes the checkout process so that every installer checks out in the same way, every time to ensure that all zones are operating correctly before leaving the jobsite. Only one installer needed for checkout. (HZ432 and HZ322 only)
Robust Push Terminals - Push-in terminal blocks wire in literally half the time compared to screw terminals - with no screwdriver required.  Plus, wires lock-in to the terminals for a tight fit.
Common-Sense LEDs - Indicate which zones are calling, what stage they are calling for (heat/cool) and when the emergency heat is on.
Universal Application - TrueZONE panels work with virtually any brand equipment for zone control of conventional, heat pump or dual fuel systems.
Clean, Professional Installation - Patented wire channel allows installer to run wires on the side, top, bottom or backside of the panel and wire anchors help hold wires in place.
Smaller Footprint - Gives installer the ability to mount TrueZONE panels anywhere - on the return duct, studs or wall next to the system. All panels are eight inches wide.
Variable-Speed Fan Control - Reduces blower speed in cooling when one zone is calling.
Discharge Temperature (DATS) Staging - Downstages equipment when discharge air temperature is near the limit. (HZ432 and HZ322)
Advanced Dual-Fuel Operation - Offers dual-fuel changeover based on outdoor temperature and/or thermostat staging. (HZ432 only)

Excellent zone control with every needed option built in. This control is best left to a professional installer. There are many factors to consider when designing a multi-zone heat/cool system. Some are compatability of parts, difficulty of installation, safety and testing.
