MON 10:00 AM HIGH LINE VOLTAGE
This overvoltage and undervoltage protection can be
disabled. Refer to chart below:
For security reasons, a special access code is required
to program the supply voltage range. The supply volt-
age range is programmed at the factory and should
only be changed by a service technician.
DISPLAYING SYSTEM SETPOINTS
The currently programmed Setpoint values can be
viewed at any time (see page 21) in SERVICE, LOCAL
or REMOTE operating mode as follows:
• Press and release the appropriate Setpoint key –
the message will be displayed for 2 seconds.
– or –
• Press and hold the appropriate Setpoint key – the

To Display CHILLED LIQUID TEMP Setpoint:
Use CHILLED LIQUID TEMP setpoint key as de-
scribed on page 9 to produce the following mes-
sage:

NOTE: The value displayed is the actual LCWT set-
point. For example, the value displayed in LO-
CAL or
PROGRAM mode is that which is op-
erator programmed. The value displayed in
the REMOTE mode is that base setpoint with
added temperature reset by an Energy Man-
agement System, via remote LCWT setpoint
(PWM signal) if a remote reset signal was re-
ceived within 30 minutes.
To Display % CURRENT LIMIT Setpoint:
Use % CURRENT LIMIT setpoint key as described
above to produce the following message:
CURRENT LIMIT = XXX % FLA
NOTE: The value displayed is the actual % current
limit setpoint. For example, the value displayed
in LOCAL or PROGRAM mode is that which
is operator programmed. The value displayed
in the REMOTE mode is that which has been
programmed by the Energy Management Sys-
tem via the remote current limit setpoint input.
If chiller is equipped with a YORK Solid State Starter,
the message is:
CURRENT LIMIT = XXX % FLA; *MTR CUR = 000 FLA
NOTE: On Solid State Starter applications, this value
is programmed at the YORK factory. A special
access code is required.
To Display PULL DOWN DEMAND Setpoint:
Use PULL DOWN DEMAND setpoint key as de-
scribed on page 10 to produce the following mes-
sage:
SETPOINT = XXX MIN @ XX % FLA XXX MIN LEFT
To Display CLOCK Setpoint (Time of Day):
Use CLOCK setpoint key as described above to
produce the following message:
TODAY IS DAY XX:XX AM/PM 1/1/92
To Display DAILY SCHEDULE Setpoints:
• Press and hold the DAILY SCHEDULE setpoint key.
