U107 Fan Setpoint
41 - 104 °F
5.0 - 40.0 °C
73 °F
22.8 °C
Required anytime the fan operates from a different sensor than that used for the temperature
setpoint. EX: temperature setpoint is set to Supply Air and the fan control is set to Remote Air.This
is considered "Optimized Aisle" control, which decouples the fan and cooling capacity modulation.
The remote sensor setpoint would modulate the fan speed and the supply sensor setpoint would
modulate the cooling.

Determines which sensor will control the speed of the fan. If set to "Manual", then the fan control
can be set through the local iCOM display or through the BMS system via one of the various
Intellislot monitoring cards.
U110
Optimized
Aisle Enabled Disabled
Enabled
Disabled
This read-only value indicates if the Liebert iCOM controller is setup in a Optimized Aisle
configuration. To enable optimized aisle via the iCOM display, the Supply Air sensor must be set to
control the cooling capacity and the remote sensor must be set to control the fan speed. This
allows the cooling unit to maintain rack temperatures whill still maintaining an even under-floor air
temperature when controlling unbalanced rooms.
U113
2nd
Temperature
Setpoint
41 - 104 °F
5.0 - 40.0 °C
73 °F
23.0 °C
Allows for a dry contact through the customer input connections. When a customer input
connection is set for 2nd temperature setpoint and that input is triggered, then the value set in this
parameter sets the active temperature setpoint the unit will maintain. If the unit is configured for
De-coupled Mode, then this setpoint will only affect the temperature control setpoint; it will not
affect the fan control setpoint.
U114
Supply Temp
Limit Setpoint
41 - 81 °F
5.0 - 27.0 °C
41 °F
5.0 °C
Selects the minimum discharge air temperature. When the actual sensor reading approaches this
parameter, the cooling capacity will be limited to avoid going below the Supply Limit Temperature
value. This parameter must be enabled in the Service Menu / Setpoints menu prior to setting a
supply limit setpoint.
U116
BMS Backup
Temp
Setpoint
41 - 104 °F
5.0 - 40.0 °C
73 °F
23.0 °C
Selects a temperature setpoint that will be activated in the event of a BMS time-out or a customer
input signal. The BMS timer and/or the customer input must be configured for this parameter to
activate. If the unit is operating in De- coupled mode, then this setpoint will only affect the
temperature control setpoint; it will not affect the fan control setpoint.
U117
BMS Backup
Fan Setpoint
41 - 104 °F
5.0 - 40.0 °C
73 °F
23.0 °C
Selects a temperature setpoint when the backup fans will be activated in the event of a BMS time-
out or a customer input signal. The BMS timer and/or customer input must be configured in order
for this parameter to activate. If the unit is operating in De-coupled mode, then this setpoint will
only affect the temperature control setpoint; it will not affect the fan control setpoint.

U119
Return
Compensation
Setpoint
41 - 104 °F 5.0
- 40.0 °C
73 °F 23.0
°C
Allows the return air sensor to be used even when in Supply or Remote temperature control mode.
Return Compensation modifies the temperature setpoint to ensure that the return air temperature
is kept above a specific temperature. If the return compensation value is set to 80 °F and the
actual return temperature falls to 75 °F, then the controlling temperature setpoint will be increased
and will reflect in the "Control Temp Act" parameter.
