Teamwork Control Options
Qty. Units included in Average
Defines the quantity of units sensor values (X) within a given network group that are included within the 'System'
average calculation and used for control. The primary unit ranks the units by temperature value of:
• Temperature Control Sensor value (for modes B and C)
• Fan Control sensor values (for modes A, D, and E).
Liebert® iCOM™ shall use the (X) highest sensor values to calculate the system average used for control.
NOTE: This parameter is only available when units are configured for Teamwork Mode and the aggregation method is
configured for "average".
NOTE: When Return Sensors are utilized for Fanspeed control, Return Sensor values on units placed in standby will
not be used within the weighted aggregation of all Return Sensor values in the network group. Only Return Sensor
values on operating units (Fan ON/Cooling ON) shall be included.
NOTE: When Remote Sensors are assigned to Fanspeed Control, Remote Sensor values on units in Standby shall be
included within the weighted average and used for control.
Cascade Units
Stages on standby units based on room temperature/humidity load. AvailableinTeamworkmodes 1 and 3, the options
differ for each:
• Teamwork mode 1 Parallel options are:
• Yes: Standby units cascade on based on a call for heating, cooling, humidification, or dehumidification.
• Cool/Heat: Standby units cascade on with a call for heating or cooling only.
• Cooling: Standby units cascade on with a call for cooling only.
• Teamwork mode 3 Optimized Aisle options are:
• Fan P: Standby units cascade on based on the inability of active units to reach setpoint temperature or if
using static pressure control, setpoint pressure while operating at full capacity.
• Fan speed: Standby units cascade on based on the inability of active units to reach setpoint temperature
or if using static pressure control, setpoint pressure while operating at full fan speed.
Cascaded Units Delay
Length of time in minutes to delay the activation of a stand-by unit after the previously activated unit starts, to prevent
staged cascaded units from starting too close together or at the same time.
Cascaded Units Min Run
Length of time in minutes that an cascade on unit must run before powering off.
Cascaded Units Off Delay
Length of time, in minutes, to delay powering-off a cascaded unit after fan speed drops below the Stop
Next Unit at SYS
Fan Speed setting.
