Irritrol MC-48E - Station Delay Time

16
Set Program – Station Delay Time
Station delay time is the adjustable delay period between station operations. The controller’s default station delay is 0
seconds. The maximum delay time you can set between station operation is 4 hours.
Assign Station Delay Time
Step 1 – Place the Function Dial to the SET PROGRAM position.
Step 2 – Enter the program number (1–8) being modied. Press the to activate the selection.
Press the
button to clear any “Key Entry Error”.
Step 3 – Press the and buttons to access the station delay function.
Step 4 – Enter the station delay duration in H MM SS (Hours, Minutes and Seconds) and press .
To disable the station delay, assign 0 for the time duration.
Example: To assign a 30-second station delay to program 1, enter 0 00 30.
Step 5 – Return the Function dial to AUTO/RUN position to exit SET PROGRAM.
To set the pump start circuit ON or OFF during the station delay, See Option 3 section.
Set Program – Looping Start Time
The MC-E has the capability to loop a program. When a program is set to loop, the program will repeat after the loop
delay time is satised. The program will continue to repeat beginning from the start time until the designated end time.
To initiate the program to loop, you must assign a start time, end time and a loop delay to the program.
Set a Looping Start Time
Step 1 – Establish a start time to the program. (See Set Program – Program Start Time section.)
Step 2 – Assign a program End time. Place the Function Dial to the SET PROGRAM position. Enter the program
number being modied. Enter to access the loop function.
Press the
button to clear any “Key Entry Error”.
Enter the program end time in H MM format and press . Use the button for PM.
Example: Enter 6:00am start time and 10:00pm end time.
Step 3 – You must assign a loop delay by entering . Enter the delay time in H MM or MM and press .
One minute loop delay is the minimum.
Example: Assign a 30-minute loop delay. Enter .
After establishing a loop, any additional program start time(s) will be deleted.
Step 4 – Return the Function dial to AUTO/RUN position to exit SET PROGRAM.
IMPORTANT! A looping program must have it’s start time and end time programmed to occur on the
same day. Looping through midnight (end time is on another day) may cause the end time to be ignored or lost.
If the Master Valve/Pump must be ON during the loop delay, program an unused station at the end of the cycle
with a runtime equal to the loop delay. Make sure the Master Valve/Pump is active for this station and the loop delay is
equal to zero.
To set the pump start circuit ON or OFF during the loop delay, See Option 3 section.
