Notes:
1. Saturation temperatures are calculated values. They are derived from applicable refrigerant pressure-temperature conversion lookup table
in the program. They will display XXX if the pressure used for the calculation is out of range.
2. Style B (and later) chillers are not equipped with an Evaporator Refrigerant Temperature Sensor (RT7). Software versions C.MLM.05.04.
xxx (and later) do not read or display this value.
