The Temperature Reset value is the maximum allow-
able remote reset of the temperature setpoint. The set-
point can be reset upwards by the use of an Energy
Management System or from the Temperature Reset
Option Board. See page 200 for a detailed explanation
of this feature.
As with the other setpoints, the ↑ (Up) arrow and ↓
(Down) arrow keys are used to change the Tempera-
ture Reset value. After using the ↑ (UP) and ↓ (DOWN)
arrows to adjust to the desired setpoint, the ENTER/
ADV key must be pressed to enter this number into
memory.

SCHEDULE/ADVANCE DAY KEY

The "Schedule" is a seven day daily schedule that al-
lows one start/stop time per day. The schedule can be
programmed Monday through Sunday with an alter-
nate holiday schedule available. If no start/stop times
are programmed, the unit will run on demand, pro-
viding the chiller is not shut off on a unit or system
shutdown. The daily schedule is considered "not pro-
grammed" when the times in the schedule are all zeros
(00:00 AM).
To set the schedule, press the SCHEDULE/ADVANCE
DAY key. The display will immediately show the fol-
lowing display.

key will enter the times and then move the cursor to
the minute box. The operation is then repeated if nec-
essary. This process may be followed until the hour,
minutes, and meridian (AM or PM) of both the START
and STOP points are set. After changing the meridian
of the stop time, pressing the ENTER/ADV key will
advance the schedule to the next day.
Whenever the daily schedule is
changed for Monday, all the other
days will change to the new Monday
schedule. This means if the Monday
times are not applicable for the whole
week then the exceptional days would
need to be reprogrammed to the de-
sired schedule.
To page to a specific day, press the SCHEDULE/AD-
VANCE DAY key until the desired day appears. The
start and stop time of each day may be programmed
differently using the ↑ (UP) and ↓ (DOWN) arrow, and
ENTER/ADV keys.
After SUN (Sunday) schedule appears on the display
a subsequent press of the SCHEDULE/ADVANCE
DAY key will display the Holiday schedule. This is a
two part display. The first reads:
H O L S T A R T
S T O P
The times may be set using the same procedure as de-
scribed above for the days of the week. After changing
the meridian of the stop time, pressing the ENTER/ADV
key will advance the schedule to the following display:
S __ M T
H O L I D A Y
The line below the empty space next to the S is the
cursor and will move to the next empty space when
the ENTER/ADV key is pressed. To set the Holiday,
the cursor is moved to the space following the day of
the week of the holiday and the ↑ (UP) arrow key is
pressed. An * will appear in the space signifying that
day as a holiday. The * can be removed by pressing the
↓ (DOWN) arrow key.
The Holiday schedule must be programmed weekly –
once the Holiday schedule runs, it will revert to the
normal daily schedule.
