Node Setting Master Valve Operation
(NODE-200, NODE-400, & NODE-600 only)
The multi station NODE models (NODE-200, NODE-400, and NODE-600) are capable of being programmed with the use of a normally closed master valve. When programming with the master valve you will be assigning station 1 as the master valve, effectively losing the use of station 1 for activation of an irrigation station.
- From the Idle Mode, press the button until the icon is displayed.
- Program A will be displayed along with the active station # on the lower left. Make sure the active station showing is #1. The run time will be shown.
- Press the minus (-) button once and the MV icon will display on the screen and the time will disappear. Station 1 is now acting as the master valve and will not be available in other programming screens.
- When the master valve is activated it will apply to all programs and the MV icon will stay displayed on the screen at all times.
