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 alternate
holiday schedule available. If no start/stop times are pro-
grammed, the unit will run on demand, providing the unit
is not shut off on a unit or system shutdown. The daily
schedule is considered "not programmed" 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 follow-
ing display.
M O N
S T A R T
S T O P
The line under the 0 is the cursor. It may be changed by
using the UP and DOWN arrow keys until correct. Press-
ing the ENTER/ADV key will enter the hours and then
move the cursor to the minute box. The operation is then
repeated if necessary. 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 me-
ridian 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 desired schedule.

mal daily schedule.
