The PID Sequencer module is responsible for sequencing the cooling tower valve and the cooling tower fans and making sure that the tower valve is open before starting the cooling tower fans. This module accepts as inputs a Delay, an Input 1, an Input 2, and a System Enable. Based on the input commands and the attribute settings, the module outputs a state for sequencing the valve and fans.

You can view and modify the modules in this group’s logic.
