Status DT3 (Room/Setpoint)—This indicates if the delta T between room return air temperature
and unit air temperature setpoint has been met.
Status Min CW—This indicates if the freecooling or chilled water temperature is below the mini-
mum chilled water setpoint.
LWD Value—(HPM only) On units with the optional analog Leakage Water Detector, this parameter
will display percent leakage from 0-100%.
Status LSI—(HPM and PEX only) On units with variable capacity steam bottle humidifiers, this
parameter shows the status of the high water level indicator.
Status Condenser 2 Failure—(HPM only) This parameter shows the status of the Condenser 2 fail-
ure indicator.

Return Sensor Alarms—This parameter enables and disables the return temperature and humid-
ity sensor alarms. Factory default is set to enable.
High Return Temperature—This parameter sets the threshold temperature when a return high
temperature alarm will occur.
Low Return Temperature—This parameter sets the threshold temperature when a return low
temperature alarm will occur.
High Return Humidity—This parameter sets the threshold humidity when a return high humidity
alarm will occur.
Low Return Humidity—This parameter sets the threshold humidity when a return low humidity
alarm will occur.
Sensor A Alarms—If the unit is equipped with the optional temperature / humidity sensor this
parameter will enable or disable the alarms associated with sensor A.
High Temperature Sensor A—This parameter sets the threshold temperature when a Sensor A
high temperature alarm will occur.
Low Temperature Sensor A—This parameter sets the threshold temperature when a Sensor A low
temperature alarm will occur.
High Humidity Sensor A—This parameter sets the threshold humidity when a Sensor A humidity
alarm will occur.
Low Humidity Sensor A—This parameter sets the threshold humidity when a Sensor A low humid-
ity alarm will occur.
