Emerson Liebert iCOM Manual De Usuario

Options Setup contains component configuration, such as enable/disable humidifier, reheat, etc.

S402 Compressor Sequence—Changes the lead compressor when cooling is activated. This 

parameter can also be set to “AUTO” mode, which will activate the compressor with the lowest run 

hours first.
S403 Low-Pressure Alarm Delay—Sets how long the unit will ignore a low-pressure condition 

during compressor startup. This parameter has previously been referred to as a Winter Start Time. 

This parameter can be set between 0 to 5 minutes.
S404 Electric Stages—Shows the number of electric stages that can be activated during a call for 

reheat. This parameter is set at the factory based on the unit’s model number.
S405 Hot Water Heat On/Off—Selectable between “Yes and No”. If YES is selected, the unit is 

equipped with a hot water heater.
S406 Total Heat Stages—Shows the number of heat stages that can be activated during a call for 

reheat. This parameter is set at the factory based on the unit’s model number.
S407 LWD Connected—This parameter is set to YES if a liquid detection device is connected to the 

Liebert iCOM.
S408 Valve Type—Displays the type of valve actuator installed, either chilled water or free-cooling. 

This parameter is factory-set and read-only. 
S409 Valve Control—Selects between two different methods to keep track of valve position when a 

stem/3P valve is installed in the unit. This setting does not affect motorized ball valves. If “Time” is 

selected, then the valve position is tracked by an internal timer in the control to determine the 

position or opening of the valve. If “Feedback” is selected, then analog input #1 interprets the signal 

from the valve to determine its position. Using the “Feedback” setting requires the setup procedure in 

3.3.3 - Chilled Water Control.
S41 3P Actuator Runtime—Sets the runtime at which the actuator will run.This parameter is 

adjustable from 30 - 500 seconds. Factory-set by unit code and should not be changed without 

contacting factory.
S411 3P Actuator Direction—Selects if the valve is a “Direct” or “Reverse” acting valve. Factory-set 

by unit code and should not be changed without contacting factory
