The Cooling Tower Control module coordinates the outputs to a cooling tower. This module supports single speed, two speed, three speed, or variable speed tower fans.

The module accepts a percent command, speed commands, and an isolation valve command to determine which outputs are active. When the fans are multi-speed, this module ensures that only the currently required speed output is active.

For information on how the FSM determines the state, see FSM (Fan Speed).
