Research Products 6203 Zone Control Panel 3 Zone 20-30VAC

Product Description

The RESEARCH PRODUCTS 6203 is a 3-zone HVAC control panel designed for single-stage heat and cool systems. It operates on 20 to 30 VAC at up to 3 amps and carries a temperature rating of 140 degrees F. The panel manages zone damper control and thermostat inputs for up to three independently controlled zones within a single forced-air system. Licensed HVAC technicians install this panel as part of a zoned comfort system, typically alongside zone dampers and low-voltage thermostats. Its straightforward layout minimizes setup time and reduces the risk of callbacks during commissioning.

The 6203 is suited for residential single-stage heating and cooling applications, including new construction and retrofit installations in existing homes. It supports 2 or 3-zone configurations, giving installers flexibility when adding zoning to an existing system or building out a new one. The panel provides all core functions required for a reliable zoned comfort system without unnecessary complexity. It is part of the Aprilaire 6200 series, which also includes the 6202 for 2-zone-only applications.

Key Features

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect power to the air handler, furnace, and any connected thermostats before wiring the control panel. Low-voltage wiring practices apply; follow NEC guidelines for Class 2 circuits. Verify all zone damper actuators and thermostats are compatible with single-stage control logic before powering the system up.
