UNIT DIAGNOSTICS CONDITION
FLASHING DISPLAY: MEANS:
A xxx A
New CMR, CAR. or IFW Diagnostic Exists.
A xxx ↔ C yyy Operating Code when MMR or MAR occurred. Diagnostic currently inhibiting operation.
b yyy Manual reset required to restore full operation. This or other latching diagnostics exist.
C yyy Condition creating MAR, CAR or IFW still exists. If MMR or CMR, manual reset required.
10 uu The chilled water setpoint is too close to a cutout setpoint.
DASHES: MEANS:
d ---- The chiller is in either ice bldg or ice bldg compl; Ivg chld wtr stpt is not applicable.
33 ---- The chiller is in normal cooling; the active ice termination setpoint is not applicable.
Other (e.g. 14----) Option either not installed or not enabled.
