Rain On/Off Switch
The Heron controller can also operate with a simple On/Off rain switch. If you have a simple ON/Off rain switch
set this option to “99”. The On/Off rain switch is also connected across I2, C2. If the switch is triggered to an
“On” (closed contact) then irrigation programs will be stopped. Irrigations programs will not run again until the
contact is in an “off” position (open contact).
8. Manual Percentage
The Manual Percentage option allows all irrigation run times to be temporarily adjusted by a specified
percentage (0%-250%). Set this option to 001 if you require manual percentage adjust.
Select “MANUAL PERCENT” from the Main Menu. Enter the required percentage adjustment.
If no increase or decrease in program run times is required, then the manual percentage value must be set
to 100%.
To half program run times, set this percentage to 50%.
To double program run times, set this option to 200%.
WARNING: If the percentage value is left at 0%, the program will not run.
9. Input 1 Use
This controls whether irrigation programs should suspend or permanently stop when the remote stop input is
activated.
If this option is set to 000, then programs will run as normal even if the remote stop is activated.
Set this option to 001 to suspend programs when the remote stop is activated. Irrigation programs will start
again from the point at which they stopped when the remote stop condition is removed.
Set this option to 002 to stop programs when the remote stop is activated. Irrigation programs will not
automatically start again when the remote stop condition is removed.
10. Input 1 Message
Setting this option will change the remote stop input message to ‘Low Tank’. To display ‘Low tank' instead of
‘Suspend’ or ‘Stop’, set this option to 001.

when the Time screen is displayed.
