The multi-station NODE models (NODE-200, NODE-400, and NODE-600) can be programmed using a normally closed master valve. When programming with the master valve, you will assign station 1 as the master valve, effectively losing the use of station 1 for activating 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 for station #1 will be shown.
Press the minus (-) button until the run time displayed disappears and the MV icon displays on the top screen. 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.
