Intermatic FF34H Timer

The Intermatic FF34H Timer is a professional-grade spring wound countdown timer engineered for heavy-duty commercial and industrial applications. As an auto-off mechanical timer, it functions without requiring an electrical connection, making it an ideal choice for energy-efficient HVAC control and lighting management. This model features a Single-Pole Double-Throw (SPDT) contact configuration, providing the versatility to either break a circuit or transfer power between two different loads at the end of the 4-hour timing cycle.

Designed for seamless integration, the FF34H fits into standard single-gang or multi-gang boxes, replacing traditional wall switches to prevent energy waste from fans, motors, or lighting left running. Its brushed metal look faceplate ensures compliance with NEC requirements while maintaining a clean, professional aesthetic. With teeter-type terminals for rapid field wiring and compatibility with LED, CFL, and incandescent loads, this unit is built to withstand the rigorous demands of mechanical rooms and commercial facilities.

• Multi-Voltage Compatibility: Operates across 125-277 VAC ranges, supporting various commercial power systems.
• Versatile SPDT Switching: Allows for flexible wiring to either shut off a primary load or activate a secondary signal upon expiration.
• No Neutral Required: Simplifies retrofitting in older buildings where neutral wires may not be present in the switch box.
• High Inductive Rating: Rated for up to 1 HP at 125 VAC and 2 HP at 250 VAC, making it suitable for direct motor control.
• Robust Mechanical Build: The analog spring-wound mechanism ensures reliable operation in environments where electronic components might fail.

Does this timer require a neutral wire for installation?
No, since this is a mechanical spring wound timer, it does not require a neutral connection or external power to operate the timing mechanism.

Can I use this to control a ventilation fan and a status light simultaneously?
Yes, the SPDT configuration allows you to manage two separate circuits, switching from one to the other when the countdown finishes.

Is this model equipped with a "Hold" feature for continuous override?
The Intermatic FF34H is a standard countdown-to-off model and does not include a permanent "Hold" position; it is designed strictly for timed intervals up to 4 hours.
