Important: As of Release 5.0, the Tower Sequencing-Vernier v50 module replaces the Tower Sequencing-Vernier module.

The Tower Sequencing-Vernier module is responsible for sequencing cooling tower fans to maintain a setpoint. This module accepts as inputs a mode, a process variable, a setpoint, a minimum on time, a minimum off time, a rotate now, process units, a device x runtime (where x is 1-12), and a device x enable (where x is 1-12). Based on the input commands and the attribute settings, the module outputs a control status, an output for modulating the vernier device, and a device x out (where x is 1-12). You can view and modify the modules in this group’s logic. The module resets the PIDs to default tuning parameters if the Reset PID Tuning input is not Normal.
