Hunter Node-600 Details
The Hunter Node-600 has a threaded two-piece body with the battery compartment inside. To fit the batteries, unscrew the rear body, place one or two batteries in the tray, and attach them with the battery connector. Check that no water has entered the compartment, then screw the halves back together. The seal marker on the rear half must line up with the front half so the unit seals properly. A rubber cover keeps dirt off the face of the controller.
To wire the six stations, connect the black lead from each solenoid to the controller's single black common wire. Then connect one red wire from each solenoid to the matching red station lead. The station numbers are printed on the face of the controller. Seal every splice with a waterproof connector. To add a rain sensor, cut the yellow wire loop near its middle and strip about ½" (13 mm) of insulation from each end. Join each yellow wire to one sensor lead.
Standard Hunter controllers use a dial, but the Node-600 is programmed with buttons. One button steps through the programming functions. The up and down buttons change whichever value is flashing, and the left and right arrows move between items. A separate button selects program A, B or C. In idle mode, the screen shows the time, the day, the MV icon (when a master valve is set) and the battery level. The screen turns off after a period of inactivity to save power, and any button press wakes it.
In run mode, the screen shows the station number, the program letter, the remaining run time and a blinking Rotor icon. You set the clock in this order: year, month, day, time format, hour and minutes. After you enter the run time for the last station, press the advance button to open the Total Run Time Calculator. It shows the total watering time for the program. Seasonal adjustment affects every program and updates the displayed run times straight away. For example, a 20-minute run time set to 50% shows as 10 minutes.
Manual Watering lets you test one station or a whole program. To start it, press and hold the button from idle mode. This mode ignores the weather sensor. While a station runs, the up and down buttons change its run time. The arrow buttons stop the current station and move to the next or previous one. To end the cycle, lower the time to zero. When the rain sensor stops watering, the umbrella icon or the System Off icon with OFF appears on the screen.
To use Sensor Bypass, press and hold the button from idle mode until the umbrella icon flashes with ON. Press once to switch to OFF. A crossed umbrella then stays on the screen as a reminder. Easy Retrieve™ saves your preferred schedule to permanent memory when you hold two buttons for five seconds. Dashed lines move from left to right, and DONE flashes when saving is complete. To restore the schedule, use the same hold. This time the dashes move from right to left. Saving a new schedule overwrites the old one.
If you set up a master valve, Station 1 becomes the master valve and no longer waters. This leaves five watering stations on the Node-600. The MV icon stays on the screen and the setting applies to every program. The battery indicator has three levels: Full (100–60%), Med (60–25%) and Low (25–0%). At Low, replace the battery right away.
To reset the controller, press and hold the three reset keys from idle mode. After two seconds the screen goes blank. Keep holding until 12:00 flashes, then release the keys. The screen may count down from 10 to 1 before 12:00 am flashes. A reset erases the current program but keeps the schedule saved with Easy Retrieve. The troubleshooting guide covers four problems: a blank screen, the display showing watering with no water flowing, missed start times, and the controller watering more than once a day.
