The Traceable® Lab Controller manages any appliance plugged in the back of the controller. In its time-of-day mode, the system may be programmed for up to 224 on/off switches per day, or up to 1568 switches per week. In the countdown mode, it turns on/off to the very second. In the repeat mode, it continually cycles equipment on/off at any two unique time intervals desired. A press of a key manually overrides the automatic settings. - Friendswood, Texas - (281) 482-1714 - www.control3.com
