Unit Remote Sensors Mode
When controlling at the unit level, selects the method of using the inlet-rack temperature readings from the control
sensors to control fan speed. Options are:
• Maximum: Use the highest temperature reading of the sensors set to Control.
• Average: Use the average of the readings from the sensors set to Control and included in AVG.
Unit Remote Sensors included in AVG
When Unit Remote Sensors Mode is Average , selects the number of sensors used to calculate the average
temperature.
• If the number selected is smaller than the number of REM Sensors set to Control, only the highest readings are
used for the calculation.
NOTE: Depending on the type of thermal management unit, included components, and control settings of your
system, all of the options listed may not be available on your iCOM display.
