ZoneFirst MDM-Z Actuator
The ZoneFirst MDM-Z Actuator is a professional-grade modulating damper motor engineered for high-precision airflow regulation in both residential and light commercial HVAC zoning systems. This 24VAC actuator utilizes a floating control signal to provide seamless positioning, ensuring accurate temperature balancing across multiple zones. Designed for power open/power closed operation, the MDM-Z is a direct replacement motor for ZoneFirst ZDM, RDM, and RRM dampers, delivering a robust 250 in-oz of torque to handle high static pressure environments without stalling.
For technicians in the field, the MDM-Z offers critical installation advantages, including built-in end switches that automatically de-energize the motor once the travel limit is reached, preventing gear wear and extending the service life of the unit. The adjustable minimum damper position allows for a bypass of air even when the zone is "closed," critical for preventing evaporator coil freeze-ups or high-limit trips on the furnace. The three-wire terminal strip (M1, M4, M6) simplifies integration with SPS or SPC static pressure controls, making it a reliable solution for modulating bypass dampers.
Key Benefits for HVAC Contractors
- High Torque Performance: Rated at 250 in-oz to maintain reliable airflow control even in high-velocity ductwork.
- Integrated Limit Switches: Internal end switches remove power at full travel to protect the motor integrity and reduce energy draw.
- Customizable Airflow: Features an adjustable minimum position stop to ensure constant ventilation or bypass requirements.
- Visual Diagnostics: Built-in LED indicators provide immediate verification of open (green) and closed (red) status during troubleshooting.
- Energy Efficiency: Low 0.17A operating current allows up to six actuators to be powered by a single 40VA transformer.
Common Questions
Is the MDM-Z compatible with old Trol-A-Temp systems?
Yes, the ZoneFirst MDM-Z is designed as a technical successor and can be used to retrofit many older damper motor configurations, provided the 24V floating signal requirements are met.
Can I use this actuator for a bypass damper?
Absolutely. When paired with a Static Pressure Switch (SPS), the MDM-Z functions as a modulating bypass actuator, adjusting automatically to maintain proper duct pressure as zone dampers open and close.
What is the travel time for this motor?
The actuator is engineered for a 90-degree rotation in approximately 8 to 10 seconds, providing the responsiveness needed for precise climate control.
