Algorithm Computer Controlled Switching provides more protection for controlled devices of all varieties by eliminating damaging short cycling. It also provides for the longest run/charge times by intelligently monitoring your electrical usage and making decisions on when the controlled device can safely operate.
Ability to fine-tune how fast the computer will decide to turn the controlled device back on after satisfying the algorithm. This allows for a testing function with instantaneous operation as well as having this set more conservatively or for faster action depending on the situation. (Standard setting is halfway through the travel)
FLA (Full Load Amp) ratings combined with LRA (Locked Rotor Amp) ratings are used to size control systems for inductive loads such as motors and provide for a diversity of applications like A/C, Heat Pumps, and Pool Pumps, etc.
§ Fail-safe design means that if the controller ever gets damaged or stops communicating with the switching device the system is designed to fail in a de-energized state preventing overloads and possible damage to people and property due to fire risk by overheating of devices or unexpected main breaker tripping and loss of whole home power
