Spring-loaded heating/air conditioning damper actuator, model RZ3-1M, 24 V, 32 in·oz, 30 s

🔧 General Description Easily replace your faulty valve actuator motor with this 2-wire spring-return actuator, designed for immediate compatibility with Honeywell models M847D1004 and M847D1012. Ideal for demanding French DIYers, it ensures precise airflow regulation in existing HVAC systems — without complications or tedious adjustments.📊 Technical Specifications Voltage: 24 V~ ±10%, 60 Hz Current: 0.36 A Torque: 32 in·oz (stable throughout the entire stroke) Speed: 30 s (motorized opening), 6 s (spring return) Rotation Angle: 93.5° Noise: ≤ 40 dB at 1 m Lifespan: 120,000 cycles (90% reliability) Material: Lightweight and robust aluminum alloy Model: RZ3-1M⚙️ Installation Intuitive installation in minutes: no special tools required. Directly replaces 2-wire "power-to-close" motors, including the M847D, Hansen 135-6, Jackson HD/D XX, Zonefirst ZDS, EWC URD, Robert Shaw DAR, and Trol-A-Temp RDMZ/RDMH — thanks to a standard 1.33-inch (33.8 mm) center-to-center spacing. 🎯 Operation: Operates in "normally open" mode: air flows freely at rest, then the damper closes upon activation. Perfect for individually controlled zones, ventilation ducts, or zoned heating systems — increased comfort, controlled energy consumption, and guaranteed quiet operation. ℹ️ Other information: Includes: 1 complete actuator (RZ3-1M). No batteries required — direct 24V~ power supply. Designed for seamless integration into existing installations, without rewiring or recalibration.
