4. We suggest that you enter a time one hour from right now. Changing this
time later is a simple matter. You go to the CHG DATA mode with "WH"
displayed and then enter the new time. Select hours (0 to 23) and press
ENTER.
5. Also enter the "WM" (minutes) and "WS" (seconds). Select minutes, press
ENTER. Wait a moment for the display to change, then select seconds and
press ENTER.
6. You have completed entering Step #1 as a "Wait Step." The display should
now read "01 NX 0002." This indicates that the 1500 is ready to move on to
program Step #2 unless you tell it otherwise.
Programming Step 2
1. Since you do indeed want to program Step #2 now, just press ENTER. The
display should read "02 SP", and you are ready to begin programming Step
#2.
Refer again to the program chart. Note that the values you want to achieve are 400
°
,
90%RH. You want the 1500 to accomplish this in four minutes. You also want to
have Ch-1 Events 1, 2 and 4 ON, and Ch-2 Events 1 and 2 ON during Step #2. We
will now program all this data for Step #2:
1. Since the display reads "02 SP," and you do want to enter Set Point Data,
first press ENTER. The display changes to "S1" (Set Point for Ch-1).
2. Use the UP/DOWN keys to put "400.0" into the display. Some practice may
be necessary to stop at the right value. Then press ENTER. The display
changes to "S2" (Set Point for Ch-2).
3. Place "090.0" into the display and press ENTER. The display changes to
"E1" (Events for Ch-1). The Data Display is blank right now.
4. In the Data Display, Event #1 is represented on the right and Event #4 is on
the left. So, for Ch-1 Events #1, 2 and 4 ON, place "1011" into the
display and press ENTER. The display will change to "E2" (Events for
Ch-2).
5. Likewise, for Ch-2 Events #1 and 2 ON, ENTER the value "0011." The
display changes to "HR" (The "hour" portion of the duration of Step #2).
6. Since Step #2 is only four minutes long, just press ENTER to enter "0000"
hours. The display changes to "MN."
7. For Step #2 Minutes, ENTER "0004." The display changes to "SC."
8. For Step #2 Seconds, ENTER "0000." The display changes to "02 00
0400."
9. You have successfully programmed Step #2 as a "Set Point Step." The
display is indicating that Step #2 is programmed for a duration of 00 hours,
04 minutes, 00 seconds. Press either ENTER or FCTN; the display
changes to "02 NX 0003."
10. Again since you do want to program Step #3 now, press ENTER. The
display
changes to "03 SP."
