The STATUS Key displays the current chiller or system
operational status. The messages displayed include
running status, cooling demand, system faults, unit
faults, VSD faults, unit warnings, external device status,
load limiting, anti-recycle timer, status of unit/system
switches, and a number of other messages. Pressing
the STATUS key will enable the operator to view the
current status of the chiller. The display will show one
message relating to the "highest priority" information
as determined by the microprocessor. The STATUS
key must be pressed twice to view both system 1/2 and
system 3/4 data. There are three types of status data,
which may appear on the display: General Status mes-
sages, Unit Safeties, and System Safeties.
When power is first applied to the control panel, the
following message displaying YORK International
Corporation, the EPROM version, date, and time will
be displayed for 2 seconds, followed by the appropriate
general status message:

Any time the STATUS key is pressed or after the
EPROM message disappears at power-up, a status dis-
play indicating chiller or system status will appear.
