It operates on a 12-hour time cycle with a variable twist-knob for setting time-on durations ranging from 15 minutes up to 12 hours depending on the model. This unit ships in a Without Hold configuration, meaning there is no constant-on position. Rated at 20 amps at 125 VAC (resistive\/inductive) and 10 amps at 250\/277 VAC (resistive\/inductive), it handles a broad range of load types including motor and tungsten loads. Electricians and electrical contractors install this device in a standard in-wall box as a direct replacement for conventional toggle or rotary switches.\u003c\/p\u003e\n\u003cp\u003eThe A512HW is suited for controlling whole house fans, bathroom exhaust fans and lights, indoor and outdoor lighting circuits, and self-storage facility lighting. Its wall-mount form factor drops into a standard single-gang electrical box, making it a practical fit for new construction and retrofit jobs alike. The simple twist-knob design requires no programming or adjustment — wire it in and the timer is operational. It carries UL approval for both Canada and the United States, making it acceptable for permitted electrical work in either market.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e12-hour spring-wound time cycle with variable twist-knob setting from 15 minutes up to 12 hours\u003c\/li\u003e\n  \u003cli\u003eWithout Hold operation — no constant-on position on this model\u003c\/li\u003e\n  \u003cli\u003eSPDT and SPST switch configurations supported\u003c\/li\u003e\n  \u003cli\u003eRated 20 amps at 125 VAC and 10 amps at 250\/277 VAC (resistive\/inductive loads); 7 amps at 125 VAC for tungsten loads\u003c\/li\u003e\n  \u003cli\u003eMotor load rated: 1 HP at 125 VAC, 2 HP at 250 VAC\u003c\/li\u003e\n  \u003cli\u003eUL listed for Canada and the United States\u003c\/li\u003e\n  \u003cli\u003eWhite color finish; standard in-wall mounting with no special tools or adjustments required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style in-wall spring-wound timer replacement for standard single-gang wall switch applications including whole house fans, bathroom fans and lights, indoor and outdoor lighting, and self-storage lighting controls.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes.
