The RHEEM hz311k is a Truzone panel kit designed for single-zone HVAC zoning systems configured for one heating stage and one cooling stage (1H/1C). The panel serves as the central control hub for a zoned forced-air system, coordinating zone damper operation and thermostat signals to manage conditioned air delivery to a single zone. Licensed HVAC technicians install this panel as part of a complete zoning solution in residential or light commercial applications. The kit includes the zoning panel needed to integrate with compatible zone dampers and thermostats.
This panel kit is suited for forced-air HVAC systems requiring basic single-zone control with one heating and one cooling output. It is typically installed in residential settings where a simplified zoning setup is needed, such as a single-zone retrofit or new construction project. The 1H/1C configuration supports conventional single-stage heating and cooling equipment.
Designed as an OEM-style replacement or new-installation component for RHEEM Truzone forced-air zoning systems requiring a 1H/1C panel configuration.
Installation of this zoning panel should be performed by a licensed HVAC technician familiar with low-voltage control wiring and zoning system design. Power down the HVAC system at the disconnect and air handler before wiring the panel. Follow applicable local mechanical and electrical codes when routing low-voltage wiring to thermostats and zone dampers. Consult the Truzone system installation guide for wiring terminal assignments and system configuration steps.
