Displays the programmed Setpoint and Range for each
system, if the chiller is programmed for Suction Pres-
sure Control mode.
Displays the Ambient Temp. at the time of the fault.
Displays which system is in the lead at the time of the
fault. This display will not be visible in Suction Pres-
sure Control mode.
Displays status of the evaporator pump and heater at the
time of the fault. Detail of the use of this contact status
is explained under the OPER DATA key.
Displays whether Remote Chiller Control was active

For this message to appear, CURRENT FEEDBACK
ONE PER SYSTEM must be programmed under the op-
tions key. If the micro is programmed as one CURRENT
FEEDBACK ONE PER UNIT under the program key, the
display will be the first display prior to the SYS 1 info. If
the micro is programmed for CURRENT FEEDBACK
NONE, no current display will appear.
Displays for System 1 starting with SYS X NUMBER
OF COMPS RUNNING X through SYS X AMPS =
XXX.X VOLTS = X.X will be displayed first, followed
by displays for System 2.
Further explanation of the above displays is covered
under the STATUS, OPER DATA, COOLING SET-
POINTS, PROGRAM, and OPTIONS keys.
