The leaving chilled water
temperature fell below the
leaving water temperature
cutout setting for 16.7°C
seconds while the chiller is in
the Stop mode, or in Auto
mode with no compressors
running. Energize Evaporator
Water Pump Relay until
diagnostic auto resets, then
return to normal evaporator
pump control. Automatic reset
occurs when the temperature
rises 2°F (1.1°C) above the
cutout setting for 30 minutes.
