Server intake temperature provided by the MCS unit
The management module constantly compares the server intake temperature to the range calculated from the
Server Intake Temperature Set Point.
•
If the server intake temperature is above the Server Intake Temperature Set Point, the opening
percentage of the water valve increases to allow more cold water to enter the heat exchanger unit.
•
If the server intake temperature is below or equal to the Server Intake Temperature Set Point, the opening
percentage of the water valve decreases to reduce the amount of cold water entering the heat
exchanger unit.
