Frequently Asked Questions

1. How do I update the rmware and language programming?

For complete instructions on how to update the rmware programming and langauges for the Sentinel system, go to the

Sentinel support website at:

http://www.toro.com/en-us/professional-contractor/irrigation/central-control-systems/Pages/Model.aspx?pid=Sentinel.

2. I have cleared all alarms, but the alarm indicator is still blinking.

ere are three possibilities: One, there may be an external alarm; the date and time might still have to be set; or three, so many

stations are running a volumetric shutdown has been triggered.

3. What happened to 2Wire/Irritrol Mode?

2Wire/Irritrol Mode has been removed from the keypad menu and is no longer being used. We do not send anything on any

port that has not been requested, so it is no longer possible to connect a 2-wire gateway. e only commands sent to that port

were for the 2-wire gateway. As a result, this ag is no longer needed.

4. Why does the time/day screen fail to synchronize?

Unlike old Sentinel systems, the new satellite stores the Schedule Reference Date. is requires the central to send the SRD. An

update to the central to send the SRD will be available soon. To avoid the issue for now, set the SRD in the central software to

Dec 7, 2009.

Note: Once the central sends the SRD, be sure to choose a SRD in the central software that is in the past.
