Path: Main > RDU > Status > Measurements
Temperatures. The temperature at each of the sensors in the RDU.
• Water In: The temperature of the chilled water entering the RDU.
• Water Out: The temperature of the chilled water leaving the RDU.
• Condenser: The temperature of the refrigerant leaving the condenser.
• Dew Point: The temperature at which condensation will occur in the conditioned environment.
• Pump Outlet: The temperature of the refrigerant leaving the pump.
• SubCool Out: The temperature of the refrigerant leaving the sub-cooler (heat exchanger).
• Cond Outlet: The temperature of refrigerant leaving the heat exchanger.
• Cond Inlet: The temperature of refrigerant entering the heat exchanger.
Pressures. The pressure sensor readings.
• Cond Out: The pressure of refrigerant leaving the heat exchanger.
• Pump 1 Head: The difference between the outlet pressure and the inlet pressure of Pump 1.
• Pump 2 Head: The difference between the outlet pressure and the inlet pressure of Pump 2.
Speed and Volume. The sensor readings displayed as RPMs or percentage of total capacity.
• Pump 1: The speed of Pump 1 as a percentage of the total capacity.
• Pump 2: The speed of Pump 2 as a percentage of the total capacity.
• CW VLV: The volume of chilled water passing through the valve, expressed in percentage of
total capacity.
• BypassVlv Pos: The volume of chilled water passing through the bypass valve, expressed in the
percentage of the total capacity.
Power. View power usage expressed in Amps.
• DC Supply 1: The amount of current used by DC power supply 1.
• DC Supply 2: The amount of current used by DC power supply 2.
• Total DC PS: The amount of current used by both DC power supplies.
Contacts. View the state of input and output contacts.
• Input State: Open or Closed
• Output State: Open or Closed
