Intermatic MIL72EQTUZH-120 Timer

The Intermatic MIL72EQTUZH-120 is a heavy-duty 24-hour electromechanical timer module engineered for high-reliability switching in light-duty commercial and industrial control panels. Featuring a robust 21A SPDT switch, this 120V quartz-drive unit is a critical component for HVACR system automation, including refrigeration merchandisers, ventilation fans, and boiler control. The flush mount design ensures a clean installation within standard panels, while its compact footprint facilitates integration into tight enclosures. For mission-critical applications, the 72-hour battery backup provides essential carry-over protection, maintaining precise timekeeping during line power interruptions without losing the programmed cycle. The manual override feature allows technicians to bypass the automated schedule for testing or emergency service without disrupting the captive tripper settings. Designed for versatility, this module handles motor load ratings up to 1 HP at 120 VAC and resistive loads up to 21A, offering consistent performance in temperature ranges from -4°F to 131°F. The intuitive clock face interface with 15-minute interval trippers permits rapid, tool-free field adjustments for optimal energy management.

• High-Capacity Switching: 21-amp SPDT contacts provide superior control for inductive motor loads and resistive heating elements.
• Quartz-Drive Accuracy: Ensures long-term timing precision with an internal, self-recharging Ni-MH battery for power outage resilience.
• Simplified Programming: Captive trippers eliminate the risk of lost parts and allow for rapid 15-minute scheduling increments.
• Flexible Mounting: Specifically optimized for flush (panel) mounting with a clear plastic dust cover to protect internal components from debris.

Common Questions

How do I set the manual override on this timer?
The unit features a 3-way manual override switch located on the face. You can toggle between permanent ON, permanent OFF, or the standard AUTO mode for programmed operation.

Can this module be used for both lighting and motor loads?
Yes, its SPDT switch rating is suitable for 1350W tungsten lighting loads and up to 1 HP motor loads at 120V, making it highly versatile for mixed-load applications.

What happens if the power goes out?
The self-recharging battery backup maintains the clock's movement for up to 72 hours, ensuring the scheduled cycles resume accurately once mains power is restored.
