It features system and zone LEDs for operational status indications and integrates a purge timer and thermal breaker to protect system components. Compatible with spring-open/power-close, spring-close/power-open, and power-open dampers, it offers automatic zone changeover and individual fan control. Operating off 20–30 VAC, the unit is engineered for durability with wide operating temperature and humidity tolerances. Key Features: Zone Control: Supports 2–3 zone configurations with automatic changeover. Thermostat Compatibility: Works with standard 4-wire Honeywell thermostats. LED Status Indicators: System (heat, cool, purge, fan) and per-zone damper LEDs. Purge Timer: Built-in 2½-minute purge cycle for safety between mode changes. Thermal Protection: Circuit breaker prevents overload and miswiring damage. Damper Compatibility: Supports multiple damper types with various actuators. Transformer Flexibility: Accepts single or dual 20–30 VAC transformer supplies. Rugged Build: Rated for –40°F to +150°F operation, 5–90% RH non-condensing. Compact Design: Wall-mountable panel sized for ease of installation. Legacy System Support: Ideal for adding zoning to existing forced-air HVAC systems. The 32003663-001 EMM‑3 delivers reliable, zone-based climate control with solid performance and HVAC protection features.
