APPENDIX C - ANALOG INPUT RANGES (LOW PRESSURE CHILLERS)

The following table indicates the valid display range
for each of the analog sensor input parameters for low
pressure chillers. In the event that the input sensor is
reading a value outside of these ranges, the less than
(<) or greater than (>) symbols will be displayed beside
the minimum or maximum value, respectively.
