For each RABS there is a Master Controller that the FFUs can be accessed from, and reports the status of the individual FFUs. The Master Controllers come in a variety of price points depending on;

The number of FFUs controlled
The customers desire for detail in the display
Whether the customer desires a screen that has been customized for their project
Whether web accessibility is required
Whether paging upon a any alarm condition is required

The function of this controller is to allow easy access to adjusting fan speed control for final balancing, while displaying the status of each FFU during day to day operations.

Virtually unlimited additional options available, per the job.
