CLOCK
The CLOCK display shows the current day, time, and
date. Pressing the CLOCK key will show the current
day, time, and date.
It is important that the date and time be correct, other-
wise the daily schedule will not function as desired if
programmed. In addition, for ease of troubleshooting
via the History printouts, the day, time, and date should
be correct.
To change the day, time, and date press the CLOCK key.
The display will show something similar to the following:
T O D A Y I S F R I 0 8 : 5 1 A M
2 5 J A N 0 8
The line under the F is the cursor. If the day is correct,
press the ENTER/ADV key. The cursor will move un-
der the 0 in 08 hours. If the day is incorrect, press the ↑
(UP) or ↓ (DOWN) arrow keys until the desired day is
displayed and then press the ENTER/ADV key at which
time the day will be accepted and the cursor will move
under the first digit of the “2 digit hour”. In a similar
manner, the hour, minute, meridian, month, day, and
year may be programmed, whenever the cursor is under
the first letter/numeral of the item. Press the ↑ (UP) or
↓ (DOWN) arrow keys until the desired hour, minute,
meridian; day, month, and year are displayed. Pressing
the ENTER/ADV Key will save the valve and move the
cursor on to the next programmable variable.
