Intermatic FM/1SWUZ-120U Timer

The Intermatic FM/1SWUZ-120U is a heavy-duty 7-day electromechanical timer module engineered for precise automated control in commercial HVACR and industrial systems. Designed for 120V AC applications, this SPDT (Single Pole Double Throw) switch features a robust 21 Amp resistive rating and is capable of handling motor loads up to 1 HP. As a veteran-grade panel mount timer, it integrates seamlessly into machine control panels, refrigeration units, and ventilation systems. The synchronous drive mechanism ensures timing accuracy across a full week, with captive trippers allowing for minimal 2-hour switching intervals. This module is the industry standard for 7-day 120V electromechanical timing, providing the reliability required for managing circulating pumps, aeration systems, and lighting circuits without the complexity of electronic controls. Its compact footprint and 1/4 inch quick-connect terminals simplify field installation and retrofitting for contractors.

• High-Capacity Switching: Rated for 21 Amps and 1 HP @ 120V, suitable for heavy electrical loads and motor applications.
• 7-Day Scheduling: Designed for complex weekly cycles rather than simple daily repeats, ideal for commercial energy management.
• Industrial-Grade Build: Features a wide operating temperature range from -40?F to 185?F for use in demanding environments.
• Simplified Wiring: Equipped with standard 1/4 inch spade terminals for fast, secure connections in control cabinets.
• True Clock Face: Provides a clear visual interface for quick time-of-day verification and manual adjustment.

Can the Intermatic FM/1SWUZ-120U be used for both heating and cooling?
Yes, the SPDT contact form allows the timer to be used for both normally open (NO) and normally closed (NC) applications, making it compatible with diverse HVACR logic.

What is the minimum switching interval for this 7-day model?
The minimum ON/OFF time is 2 hours, controlled by the captive trippers on the 7-day dial.

Does this unit require a separate mounting base?
This is a panel mount timer module intended to be secured directly into a cut-out in a control panel or equipment housing.
