Questions about this item
Does the spring-wound mechanism produce any audible ticking or humming during continuous 24-hour operation?
The mechanical spring-wound design operates without an electric motor, so it runs silently with no ticking or humming noise during extended use.
What voltage supply and wiring does the FF12H8 require for installation?
It connects to a 120/277V AC circuit and is rated for 1 hp at 120V or 2 hp at 240V, using standard electrical wiring for the load.
Can this timer control an older 120V motor load without an external contactor?
Yes, the single-gang timer directly switches loads up to 1 hp at 120V, so many legacy motors can be wired straight to its contacts.
