Press the ENTER key: the display will flash, then it will change to “MN.”
Use the UP/DOWN keys to place the correct value for minutes into the Data
Display; then press ENTER.
The display will show “SC” (seconds): again use the UP/DOWN keys to place
seconds into the display and then press ENTER.
Press the FCTN key several times until the TlME LED is lit (along with the CHG
PARA LED). You should now see the correct real time on the display, with
the seconds counting up.
Set the Recycle Option
Now, while still in the CHG PARA mode, there is one more thing to enter. Remember
that you want your program to automatically repeat each day until you decide to halt it.
This “Recycle” condition is set within the “Guarded Access” (GA) section of the CHG
PARA mode. Do that now:
1. With the CHG PARA LED ON, press the FCTN key until “GA” appears in the
Function Display. If you pass GA, keep pressing FCTN until GA comes
around again.
2. Place “0006,” one of the Guarded Access codes, into the Data Display using
the UP/DOWN keys.
3. Press ENTER until the "RC," (Recycle) prompt appears in the Function
Display.
4. Place a “0001” into the Data Display. Press ENTER.
Begin Entering Data
Now that you have entered the real time and the Recycle option, go to the CHG
DATA mode to enter actual program data:
1. Press the MODE key until the CHG DATA LED is lit. The display will read
“01 SP.”
Programming Step 1
Refer back to the sample program chart at the beginning of this section. Remember,
that while you’d like to load your program and press the start button now, the first
program step must hypothetically wait until early morning before it starts running. To
program Step #1 as a Wait Step,” do this:
1. Press the FCTN key until "WT" appears in the Function Display.
2. Press the ENTER key, W1” (Wait for Ch-1) appears.
3. Since you are waiting for a specific time, and not for input conditions, press
FCTN until “WH” (Wait for Hours) appears.
