Intermatic MIL72AQWUZH-120 Timer

The Intermatic MIL72AQWUZH-120 is a heavy-duty 7-day electromechanical timer module engineered for high-demand commercial and industrial environments. This 120V quartz drive timer features a proactive 150-hour battery backup (quartz carryover), ensuring your programmed schedules remain intact during power interruptions. Designed for ultimate versatility, this unit supports surface and DIN rail mounting, making it a drop-in solution for control panels governing HVACR systems, 1 HP motors, and lighting circuits. With a robust 21 Amp SPDT switch rating, it comfortably handles resistive, inductive, and tungsten loads. The manual override switch (ON/AUTO/OFF) allows for immediate circuit testing or bypass without disrupting the captive trippers, which are set at precise 2-hour intervals for a full 7-day cycle. Encased in a clear plastic dust cover, the MIL72AQWUZH-120 provides a visible true clock face for fast status verification on the job site.

• Quartz Drive Reliability: Integrated battery backup maintains timing accuracy for up to 150 hours during outages.
• High Capacity Switching: Features a 21A SPDT relay capable of managing 1 HP at 120VAC or 2 HP at 240VAC.
• Flexible Installation: Compatible with DIN rail and surface mount enclosures for efficient panel integration.
• Precise Scheduling: 7-day program dial with captive trippers eliminates the risk of lost pins.
• Manual Override: Simplifies troubleshooting with a physical 3-way toggle for manual control.

How do I set the 7-day schedule?
Rotate the outer dial until the current day and time align with the arrow. Push the captive trippers outward for "ON" periods; each tripper represents a 2-hour window on this 7-day electromechanical module.

What is the difference between the Synchronous and Quartz models?
The "Q" in MIL72AQWUZH-120 indicates a quartz drive. Unlike synchronous models that stop during power loss, this unit uses a self-recharging battery backup to keep the clock running.

Can this be used for outdoor applications?
This module is intended to be mounted inside a NEMA-rated enclosure or a control panel. For outdoor use, ensure it is protected within an appropriate weather-tight housing.
