Intermatic GM40AV-Q Timer
The Intermatic GM40AV-Q is a professional-grade auto-voltage electromechanical time switch designed for versatile control in demanding HVACR and commercial environments. This 40A DPDT timer eliminates the need for manual DIP switch or selector pin adjustments by automatically detecting input voltages ranging from 120V to 277V. Built for reliability, this unit features captive trippers that cannot be misplaced and a true clock face to simplify scheduling for technicians. The "Q" model is specifically engineered with a 72-hour battery backup (carry-over) to maintain accurate timekeeping during power interruptions, preventing the need for site visits to recalibrate the system. Housed in a NEMA 3R outdoor enclosure, the Intermatic GM40AV-Q timer is suitable for controlling high-amperage loads including commercial refrigeration, pool pumps, lighting, and air movement systems. Its 24-hour/7-day programming flexibility, combined with 2 NO and 2 NC contacts, ensures seamless integration into complex multi-circuit electrical setups.
Key Benefits:
- Universal Voltage Detection: Automatically senses 120, 208, 240, or 277 VAC, reducing inventory needs and installation errors.
- Enhanced Power Protection: Includes a self-recharging battery providing 72 hours of quartz drive carry-over.
- High Capacity Switching: Heavy-duty 40 Amp resistive rating and 2 HP motor load capacity for industrial applications.
- Weatherproof Reliability: Type 3R plastic enclosure protects internal components from rain, sleet, and snow.
- Maintenance-Friendly Design: Features an ON/OFF/AUTO manual override switch and visible LED power/status indicators.
Common Questions:
How do I set the schedule on the Intermatic GM40AV-Q?
The timer utilizes 96 captive trippers on the outer dial. Push the trippers outward for the desired "ON" periods and inward for "OFF." Each tripper represents a 15-minute interval for 24-hour models.
Can this timer be used for both indoor and outdoor installations?
Yes, the NEMA 3R enclosure is designed to protect electrical connections in both indoor and outdoor environments, making it ideal for rooftop HVAC units or pump houses.
What happens to the timer during a power outage?
Because this is the quartz version (GM40AV-Q), the internal battery will keep the clock mechanism running for up to three days, ensuring your scheduled cycles resume immediately when power is restored.
