ZoneFirst MMP3 Control Panel Kit

The ZoneFirst MMP3 Control Panel Kit is a field-proven HVAC zoning system designed for contractors managing 2 or 3 zones on single-stage heating and cooling equipment. Engineered for rapid deployment, this mini-master zone control handles gas-oil-electric furnaces, hydro-air systems, and air conditioning units. It utilizes a plug-and-play architecture specifically for modular damper actuators, significantly reducing field wiring time. The board features color-coded, screw-less terminal blocks for 4- or 5-wire thermostat integration and includes built-in LED indicators for real-time diagnostics of system status and zone calls. Its intelligent changeover logic includes a 20-minute maximum run time before switching modes and a 2-minute purge period to dissipate conditioned air. This compact, rugged 3-zone control panel is the go-to solution for enhancing system efficiency and individual room-by-room temperature control in residential and light commercial applications.

• Reduced Installation Labor: Uses RJ11 plug-in damper connectors and push-in terminal blocks to eliminate complex wiring and manual stripping.
• Universal Thermostat Compatibility: Operates seamlessly with standard 24VAC thermostats, including modern smart thermostats and setback thermostats.
• Advanced System Logic: Integral automatic changeover, purge mode, and electronic short circuit protection prevent equipment damage and temperature overshooting.
• Flexible Configuration: On-board jumpers allow for Fan-on-in-Heat (FIH) settings, ideal for hydro-air or electric heat applications.
• Simplified Troubleshooting: High-visibility LED status lights confirm power, system mode, and individual zone activity at a glance.

• Which dampers are compatible with the MMP3? This panel is specifically engineered for ZoneFirst plug-in dampers (such as RDP, ZDSP, and RTP models) using modular cords.
• Can I use this for a heat pump system? No, the MMP3 is designed for single-stage conventional heating and cooling. For heat pump applications, verify specific board requirements.
• What power supply is required? It is recommended to use a dedicated 24V 40VA transformer to ensure the panel and all connected dampers receive stable voltage.
• How does the changeover work? The panel follows a "first call, first served" logic with a 20-minute timer. If an opposite call occurs, the system will switch modes after the initial zone is satisfied or the timer expires.
