Intermatic FM1D14-LV-U Timer

The Intermatic FM1D14-LV-U is a high-performance 24-hour/7-day electronic timer module designed for precise control in commercial and industrial HVACR, lighting, and ventilation systems. Operating on a versatile 24VAC/DC power supply, this SPDT (Single Pole Double Throw) digital switch supports up to 14 programmable setpoints, allowing for complex scheduling across a full week. Its robust 15A rating makes it a reliable choice for managing refrigeration merchandisers, septic treatment pumps, and aeration cycles where timing accuracy is critical. Designed for flexibility, the module supports panel, surface, or DIN rail mounting, and features a clear dust cover to protect the electronic components from harsh environment debris.

Technicians will appreciate the integrated self-recharging battery backup, which maintains your custom programming for up to 2,500 hours during power outages, eliminating the need for call-backs to reset schedules. The large LCD and manual override button with status indication simplify onsite testing and commissioning. Whether you are automating generator exercising or cycling industrial ventilation, the Intermatic FM1D14-LV-U timer delivers the industrial-grade durability required for professional HVACR controls and electrical load management.

• Universal Voltage Compatibility: Operates efficiently on 24VAC/DC systems, ideal for low-voltage control circuits.
• Flexible Scheduling: 14 distinct programs allow for both 24-hour and 7-day configurations to meet specific site requirements.
• Long-Term Memory: The internal battery backup ensures settings are preserved for over 100 days without primary power.
• Versatile Mounting: Simple panel mount or DIN rail installation adapts to various enclosure types.
• High Amperage Capacity: Rated for 15A general purpose loads, handling inductive and resistive circuits with ease.

• How do I handle manual overrides? Use the dedicated "OVR" button on the faceplate to toggle the SPDT relay status without interrupting your long-term programmed schedules.
• Is this suitable for outdoor use? While it includes a dust cover, it should be installed within a NEMA-rated enclosure if used in outdoor HVACR applications to protect against moisture.
• Can I program different schedules for the weekend? Yes, the 7-day programming allows for unique ON/OFF setpoints for individual days or blocks of days.
