Chilled Water Fluid Type Selection — The chilled water fluid must be configured. The fluid type must be config- ured to obtain the proper leaving water set point control range and freeze protection. The Cooler Fluid Type (Cooler Fluid Type, FLUD) can be set to water or brine.

FRESH WATER — Configure the unit for Cooler Fluid Type (Cooler Fluid Type, FLUD) to water for units without brine or glycol installed in the chilled water loop. The factory default fluid type is fresh water. Use this option for fresh water sys- tems. This will allow for a water temperature set point of 38 to 60 F (3.3 to 15.5 C). With water as the selection, the Freeze Point is fixed at 34 F (1.1 C).

BRINE OR GLYCOL OPERATION — Configure the unit for Cooler Fluid Type (Cooler Fluid Type, FLUD) to brine for brine or glycol chilled water loops. This option will allow for a set point temperature range of 14 to 60 F (–10.0 to 15.5 C). Before configuring this selection, confirm that a suitable anti- freeze has been added and is at a sufficient concentration to protect the loop. Additionally, the Brine Freeze Set Point (Brine Freeze Setpoint, LOSP) must be set for proper freeze protection operation. Set the Brine Freeze Set Point to the burst protection provided by the glycol concentration. This value will be Freeze Point for the fluid.
