A reference sensor can be connected to any type of Liebert iCOM unit. When an optional temperature and humidity or the optional 2T sensor is connected and set as Sensor C, then its value will be displayed on this line. Liebert iCOM will auto detect what type of sensor is connected. Sensor C can only be used as a reference sensor for reading and monitoring not for control purposes. Sensor C is selected by setting the DIP switches on the temperature and humidity board. Refer to manual for the correct settings. This sensor setting is also used as the outdoor sensor in Air Economizer Applications.
Freecooling Fluid Temperature—Displays the temperature of the incoming water on units equipped with a free-cooling coil.
Outdoor Temperature—Reads the outdoor temperature for free-cooling and dual cool units to determine if cooling can be provided without compressor operation. It is determined by comparing the temp between the room and outdoor air temperature. Available only on Liebert HPM™ units.
Freecooling Status—Displays whether free-cooling is available for use, based on the return air temperature and the incoming fluid temperature.
DigiScroll 1 Temperature—Shows the actual digital scroll number 1 discharge temperature on units with digital scroll compressors.
Fixed Scroll 1/2 Temperature— Shows the actual digital scroll number 2 head temperature on units with digital scroll compressors.
Current Static Pressure—Status of the current static pressure of the unit.
Current SYS Static Pressure—Status of the system static pressure where multiple static pressure sensor are shared across the team work network.
Calculated Airflow—Status shows the calculated airflow based on an installed differential pressure transducers.
