Intermatic FM/1 Qwuz 7 Day Analog Timer 21A Panel Mount

Product Description

The INTERMATIC FM/1 QWUZ is a 7-day analog electromechanical timer designed for reliable scheduling in both indoor and outdoor environments. It operates on 24/120/208/240 VAC at 60 Hz, making it compatible with a wide range of single-phase circuits commonly found in HVAC, lighting, and general electrical control applications. Rated at 21 amps with an SPDT contact form, this panel-mount unit provides the current capacity and switching flexibility that licensed electricians and HVAC technicians require. The analog dial interface requires no programming software or digital interface, keeping setup fast and straightforward on the job.

This timer is suited for residential and light commercial panel installations where a durable, time-proven electromechanical scheduling solution is needed. Its multi-voltage compatibility across 24, 120, 208, and 240 VAC makes it adaptable to low-voltage control circuits, standard branch circuits, and commercial 208/240 VAC loads. Typical applications include HVAC equipment scheduling, pump control, lighting circuits, and ventilation systems. The indoor/outdoor rating extends its usefulness to exterior panel enclosures and equipment rooms subject to varying environmental conditions.

Installation Notes

Installation should be performed by a qualified electrician or licensed HVAC technician in accordance with NEC requirements and any applicable local codes. De-energize the circuit at the breaker panel and verify the absence of voltage before wiring. Confirm that the connected load does not exceed the 21-amp rating of the timer. Secure the unit to the panel per the mounting instructions and set the analog dial to the correct current time before programming ON/OFF trippers.
