of Range Alarm is activated. This parameter range is adjustable from 0.000 - 1.405 inWC. The default
setting is 1.284 inWC.
U241 SP Transducer Low Range —Sets the pressure range at which the Low Static Pressure Out
of Range Alarm is activated. This parameter range is adjustable from 0.000 - 1.395 inWC. The default

U301 Optional Sensor A1T —Shows the Sensor A temperature value if optional reference sensor is
connected to the Liebert iCOM controller area network (CAN) bus. A reference sensor can be
connected to any type of Liebert iCOM unit.
This window shows the actual setpoints (read only) for temperature and humidity, as well as the
values from all standard and optional sensors.
U302 Optional Sensor A2H —Shows the Sensor A humidity value if optional reference sensor is
connected to the Liebert iCOM controller area network (CAN) bus. A reference sensor can be
connected to any type of Liebert iCOM unit. Sensor A can only be used as a reference sensor for
reading and monitoring but not for control purposes. Sensor A is selected by setting the DIP switches
on the temperature and humidity board. Refer to 4.3.2 - DIP Switch Settings .
U303 Optional Sensor B1T/B2T —Shows the Sensor B temperature value if optional reference
sensor is connected to the Liebert iCOM controller area network (CAN) bus. 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 B, then its value will be displayed on this line.
Liebert iCOM will auto detect what type of sensor is connected. Sensor B can only be used as a
reference sensor for reading and monitoring but not for control purposes. Sensor B is selected by
setting the DIP switches on the temperature and humidity board. Refer to 4.3.2 - DIP Switch
Settings .
NOTE
The unit of measure can be selected as °F or °C in the Display Setup menu.
