PROGRAM MENU
5.5 Ext. Condition
The Ext Condition program allows starting and/or stopping irrigation according to dry contacts or analog sensor.
In addition, it is possible to define an output called Cond. This output will be active whenever the condition program
settings are met. This enables using the condition program to start any external device.
Refer to Analog Input 1-2, page 126 for details on configuring this window.

• From (hh:mm): Set the start time of the condition program.
• To (hh:mm): Set the end time of the condition program
The condition program will only be operational in the defined time window (between start "From" to end "To" times).
Each condition program can be operational on different hours.
• Start An. Dry Con.: Set the analog sensor or dry contact number for starting the irrigation.
• Trigger Type: Choose one of three trigger types:
One Shot: If the Start Dry Contact is closed for more than 20 seconds the associated irrigation program
will be started. The contact must open and close to initiate irrigation.
Multi shot: If the Start Dry Contact is closed for more than 20 seconds the associated irrigation
program will be started. If the contact is still closed when the irrigation has finished, irrigation will be
initiated.
Note: Notice that the Start Dry Contact does not necessarily have to open and close in order to initiate irrigation. It
simply has to be closed when the irrigation has finished.
Only If On: The associated Irrigation program will be turned on, providing the Start Dry Contact has
been closed for more than 20 second and will remain on as long as the contact is closed.
• Stop An. Dry Con.: Set the analog sensor or dry contact number for stopping the irrigation. Since the Stop
Dry Contact is "stronger" than the Start Dry Contact, the associated irrigation program will not be started as
long as the Stop Dry Contact is closed.
