The APCTART2 is a cycle timer controller with day and night detection. It works to control any application requiring a device to be turned on and off at precise intervals. This timer has a wide range of uses including controlling hydroponic pumps, CO2 injection, turning on and off exhaust fans, misters and more.
The cycle timer is adjustable for operation during the day, during the night, or all of the time (24 hours). We added a Memory-lock feature which will lock the set points into memory for consistent performance, even if the knobs are accidentally bumped.
