Switch to DX: On energy saver modes, if chilled water is cooling continuously
without DX assistance for more than the “Switch to DX” time setting, the unit will
switch to DX cooling for one hour to exercise the compressors.
Water Flush Cycle: When the unit is on, but no CW cooling has occurred for
100hrs, the CW valve will be opened 100% for a period of 60 seconds.
Safeties for CW Cooling: The CW valve will close under the following conditions:
Condensation alarm, Air Flow alarm, or if the BMS sends a Cooling Inhibit
command.
The CW valve will fully open under the following conditions: Temperature sensor
failure, Humidity sensor failure, Water Flush Cycle, or when the Dehumidification
function is running.
