Control Wizard Heavy Duty Timer. 120-volt dual outlet with ON/OFF switch. The Red ON/OFF switch disengages the timer from the outlets (down position). The outlets will give constant power to equipment when the ON/OFF switch is disengaged or in the OFF/down position. It has 96 ON/OFF settings with an AM/PM dial. Simply push down a tripper for 15 minutes of ON time. Maximum total draw is 15 amps. Made for metal halide/HPS lighting and hydroponic pumps and blowers. The easiest timer I have ever used!Please note that the Red ON/OFF switch disengages the timer from the outlets letting the outlets have constant power just like you plugged into a standard home wall outlet (down position). ON (up position) engages the timer mechanism allowing you to time equipment. Control wizard heavy duty timer. Ti100
