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.
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
S41A Minimum Valve Pulse—Sets the minimum valve pulse % when a movement is requested.
This parameter is adjustable from 0 - 10%. The default setting is 5%.
S41B CW Valve Delay / Power Off Time—Sets the delay time of the CW valve movement when
power is lost. If power is lost, the valve will not move for the time entered into this parameter so the
unit has time to come back online from a power loss. This parameter is adjustable from 0 - 60
minutes. The default setting is 5 minutes. Sets the Power Off time; if power has been lost for the time
entered into this parameter, the CW delay will be ignored. This parameter is adjustable from 0 - 300
minutes. The default setting is 30 minutes.
