Load Limiting Modes

Night Quiet load limiting mode will reduce sound levels of the unit overnight. When active, the Night Quiet feature limits the

maximum fan speed and uses a Night Quiet specific dry switchpoint. This will allow the cooler to run adiabatically at lower

outside air temperatures to maintain capacity. The Night Quiet feature can be activated on the touchscreen, through the BMS,

or by a schedule, so that the user can define a start time on one day and a stop time on the next day. All times are in a 24-hour

format.

Night Dry load limiting mode will prevent adiabatic operation of the unit overnight and can be activated by a schedule, so that

the user defines a start time on one day and a stop time on the next day. All times shall be in 24-hour format.

Schedule Dry load limiting mode prevents adiabatic operation during the day and can be activated by a schedule, so that the

user defines a start time on one day and a stop time on the same day. All times shall be in 24-hour format.

Coil Clean is a scheduled maintenance mode that will remove loose debris from the coil surface, ensuring maximum energy

efficiency. Coil clean reverses fan rotation and airflow while opening the make-up and drain valve if the outside air temperature

is greater than 40°F (4°C) to flush debris down the drain.

Pad Clean is a scheduled maintenance mode that removes loose debris from the adiabatic pre-cooler pad surface, ensuring

maximum energy efficiency. Pad clean will open the make-up and drain valves to flush the pads with clean water.

Complete Drain and Dry is a scheduled maintenance mode that fully drains the sump and dries out the adiabatic pre-cooler

pads.
