Controls any appliance plugged into the back of the controller. In the time- of-day mode, it may be programmed for up to 224 on/off switchings per day or up to 1568 switchings 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. Three independent timing channels may be used to countdown and alarm, count-up (stopwatch mode), or countdown repeat (repetitively alarms at a specific time interval).
