MAINTAIN SETPOINT AS FOLLOWS:

· THE CONTROLLER SHALL MODULATE THE LEAD VFD TO MAINTAIN SETPOINT.

· IF THE LEAD VFD SPEED IS GREATER THAN A SETPOINT OF 90% (ADJ.), THE LAG VFD

SHALL STAGE ON.

· THE LAG VFD SHALL RAMP UP TO MATCH THE LEAD VFD SPEED AND THEN RUN IN

UNISON WITH THE LEAD VFD TO MAINTAIN SETPOINT.

ON RISING LOOP WATER DIFFERENTIAL PRESSURE, THE VFDS SHALL RUN TO MAINTAIN

SETPOINT AS FOLLOWS:

· IF THE VFD SPEEDS THEN DROPS BACK TO 60% (ADJ.) BELOW SETPOINT, THE LAG

VFD SHALL STAGE OFF.

· THE LEAD VFD SHALL CONTINUE TO RUN TO MAINTAIN SETPOINT.

ALARMS SHALL BE PROVIDED AS FOLLOWS:

· HIGH LOOP WATER DIFFERENTIAL PRESSURE: IF THE LOOP WATER DIFFERENTIAL

PRESSURE IS 25% (ADJ.) GREATER THAN SETPOINT.

· LOW LOOP WATER DIFFERENTIAL PRESSURE: IF THE LOOP WATER DIFFERENTIAL

PRESSURE IS 25% (ADJ.) LESS THAN SETPOINT.
