Service menus allow customized settings for site operations. Service Menu screens employ a coding that begins with “S” and is followed by parameters and information, such as settings. Gaining access to most Service Menus requires entering a password; the Service Menu password is 5010; see 4.3.3 - Entering the Password for assistance.
The Liebert iCOM control firmware is being updated constantly. As a result, the Service Menu parameters in this manual may be slightly different from what is shown on a cooling unit’s display.

UNIT 01
Liebert iCOM Control—Firmware Version XP1.00.010.STD Min Room Temperature Setpoint—Sets the minimum room temperature the unit will attempt to maintain. If the temperature falls below this point, unit will raise the refrigerant temperature to reduce the amount of cooling. Adjustable from 50 to 80°F (10.0 to 26.7°C), the factory default setting is 60°F (15.6°C).
Temperature Control Type—Selects the type of control the system will use to activate cooling. The Liebert iCOM control has three temperature control types: Proportional, PI and Intelligent. The factory default is Intelligent.
Proportional—If Proportional Control is selected, the percent cooling requirement is
determined by the difference between the air temperature sensor reading and the temperature setpoint. As the air temperature rises above the temperature setpoint, the percent cooling required increases proportionally (from 0 to 100%) over half the programmable temperature proportional band. The percent heating requirement (0 to 100%) is determined the same way when the air temperature falls below the setpoint.
PI—If PI Control is selected, the percent cooling requirement is calculated by adding together two individual terms, proportional and integral. The proportional term is calculated in a manner similar to the previously described Proportional control. The integral term (sometimes called reset action) is calculated by measuring how much and for how long the air temperature has been above or below the setpoint. If the actual air temperature is above the setpoint, the percent requirement is slowly but continuously increased until the total is sufficient to bring the return room air back to the setpoint.
Intelligent—If Intelligent Control is selected, the air temperature is controlled at or near the setpoint. The percent temperature adjustment required is calculated based on logic that is programmed into the control. These rules simulate the actions that would be taken by a human operator manually controlling the system.
Temperature Proportional Band—Adjusts the activation points of compressors or rate of change based on the actual sensor values deviation from setpoint. The smaller this number the faster the compressors and valve(s) will increase capacity. Too small of a number may cause the unit to short cycle the compressors or excessively reposition the valve. This parameter is adjustable from 1.8 to 54.0°F (1.0 to 30.0°C). The factory default setting is 7.0°F (3.9°C).
Temperature Integration Time—Temperature integration takes into consideration the amount of time the actual temperature has deviated from the setpoint. The larger this deviation is the longer the unit will wait before corrective action is taken to achieve the setpoint. This parameter is adjustable from 0 to 15 minutes. The factory default is 0.
Temperature Derivative Time—Monitors the rate of change and will reduce or increase the amount of corrective action based on the actual temperature increasing or decreasing toward the temperature setpoint. This parameter is adjustable from 0-900 seconds. The factory default is 0.
Dewpoint Margin—Selects the difference between the room dew point and the refrigerant
temperature control point. This parameter is adjustable from 4.0 to 10.0°F (2.2 to 6.0°C). The factory default setting is 4.0°F (2.2°C).
Minimum Control Point—Sets the minimum supply refrigerant temperature the Liebert XDP will maintain. This parameter is adjustable from 40 to 80°F (4.4 to 27.0°C). The factory default is 55°F (12.8°C).
Min Percent Cooling Setpoint—Selects the lowest percent call for cooling during normal operations. Whenever the unit is not in startup mode or OFF, the percent call for cooling cannot go below this value. The parameter is adjustable from 5 to 30%. The factory default is 15%.
NOTE
This is not a true room temperature setpoint. The Liebert XDP has no heaters; it will try to cool as much as possible. If the Liebert XDP is able to cool the room to this setpoint, it will reduce its cooling action to try to keep the room temperature at or above this setpoint.
