Zonefirst MMZ3 Control Panel Refrigerant Versatile SPDT Logic: Single-pole

Versatile SPDT Logic: Single-pole

Engineered for 480V AC 60Hz electrical systems

Technicians should check for continuity across the coil leads using a multimeter or verify the presence of a magnetic field at the coil core when the 24V signal is applied

Durable SPDT Switch: Provides the flexibility to open or close circuits on temperature rise

Zonefirst MMZ3 Control Panel Refrigerant Versatile SPDT Logic: Single-poleThe Zonefirst MMZ3 is a purpose built zoning control panel engineered for single stage heating and cooling systems. As the direct replacement for CMM 3 legacy boards, the MMZ3 provides seamless modularity for managing 2 or 3 independent zones with 24Vac 2 or 3 wire damper actuators. This panel features advanced surface mount technology for maximum reliability and utilizes color coded, screwless terminal blocks to significantly reduce installation time
