Intermatic FM/1STUZ-240U Timer

The Intermatic FM/1STUZ-240U is a heavy-duty, 24-hour electromechanical timer module engineered for high-demand integration within machine control panels and HVAC systems. Professionals rely on this synchronous drive module for its robust 21A resistive capacity and versatile 120-250 VAC range, making it a staple for equipment scheduling in commercial refrigeration, ventilation, and lighting automation. Its SPDT switching action (1 NO / 1 NC) provides direct control for loads up to 2 HP at 240V, while the captive trippers enable precise 15-minute interval programming without the risk of lost components.

Designed with a compact 2.36-inch square footprint, the FM1STUZ-240U facilitates rapid field installation via 1/4-inch quick-connect terminals. This industrial-grade timer operates reliably across extreme environments, featuring a temperature rating of -40?F to 185?F. Whether you are managing pump circulation, aerobic waste systems, or facility-wide air movement, this panel mount timer delivers the "set-and-forget" durability required in professional technical environments where downtime is not an option.

• High Amperage Rating: Rated for 21 Amps resistive and up to 2 HP motor loads, supporting heavy-duty industrial equipment.
• Flexible Programming: Features captive 15-minute trippers on a 24-hour dial for consistent, repeatable scheduling.
• Broad Environment Compatibility: Operates efficiently in extreme temperatures from -40?F to 185?F (-40?C to 85?C).
• Simplified Integration: Universal panel mount design with standard quick-connect terminals allows for fast retrofitting.
• SPDT Versatility: Single Pole Double Throw configuration allows for controlling both normally open and normally closed circuits.

Is the Intermatic FM1STUZ-240U compatible with motor loads?
Yes, it is rated for up to 2 HP at 240 VAC and 1 HP at 120 VAC, making it suitable for pumps and blower motors.

Can I use this timer to replace an existing FM1 series module?
Provided the voltage requirements match (208/240V), this module is a direct drop-in replacement for standard FM1 series 24-hour panel mounts.

Does this unit include a manual override?
The base FM1STUZ-240U model focuses on synchronous timing; models with a manual override typically include an 'H' suffix in the part number.
