a) The leaving chilled water temperature fell below the leaving
water temp cutout setting for 16.6°C- seconds while the
Chiller is in the Stop mode, or in Auto mode with no
compressors running. Energize Evap Water pump Relay
Energized] until diagnostic auto resets, then return to normal evap
pump control. Automatic reset occurs when the temp rises
1.1°C above the cutout setting for 30 minutes. When this
diagnostic is active AND Leaving Water Temperature sensor
diagnostic (loss of comm or out of range) the Evap Water
pump relay shall be de-energized.
b) If evaporator protection temperature sensors are installed,
the effect is on the appropriate circuit. Else, the effect is on
the chiller.
Any Ckt[s] a) The chilled water temperature fell below the cutout
setpoint for 16.6°C-seconds while a compressor was
Energizd] running. Automatic reset occurs when the temperature
rises 1.1°C above the cutout setting for 2 minutes. This
diagnostic shall not de-energize the Evaporator Water Pump
Output. If this diagnostic is active the Low Evap Leaving
Water Temp: Unit Off diagnostic shall be suppressed.
b) If evaporator protection temperature sensors are installed,
the effect is on the appropriate circuit. Else, the effect is on
the chiller.
The Evaporator Saturated Refrigerant Temperature dropped
below the Low Refrigerant Temperature Cutout Setpoint for
16.6°C-seconds.
