Low Water Temperature Cutout
The CXM control senses low water temperature
utilizing thermistor FP1. Note that the FP1 thermistor is
located on the refrigerant line between the coaxial heat
exchanger and the cap tube. Therefore, FP1 is sensing
refrigerant temperature, not water temperature, which is
a better indication of how water flow rate/temperature is
affecting the refrigeration circuit.
The factory setting for FP1 is 0°F [-1.1°C] refrigerant
temperature. HC series equipment is not rated for
extended range applications.
