NODE Support

Welcome to the NODE irrigation controller support section.  The NODE is a battery-powered controller that is programmed with buttons, instead of a dial like most irrigation controllers. This section will show you how to install, program and troubleshoot your NODE irrigation controller.

  • Components
    This section provides a brief overview of some of the components of the NODE . Each item will be discussed in further detail later . However, this section can be helpful in getting
  • Connecting Batteries
  • Attaching Solenoids
    The NODE-100 is provided with or without a solenoid attached to the controller. The NODE-200, NODE-400, and NODE-600 multi-station controllers will operate up to 2, 4, or 6
  • Mounting NODE
    The NODE can easily be mounted on any Hunter valve and solenoid. A specially designed valve mounting clip makes installation a snap. A protective rubber cover is provided to
  • Connecting a Weather Sensor
    A Hunter Mini-Clik® or Rain-Clik® rain sensor can be connected to the NODE. The purpose of this sensor is to stop watering when weather conditions dictate. NOTE: When the Rain
  • About Programing
    Node Program Capablities The NODE uses standard Hunter controller programming with 3 programs (A, B, C) and 4 start times per program.
  • Setting the Date and Time
    Push the button until the icon is displayed. All 4 digits will be displayed representing the year. Use the   or   buttons to change the year. Press the   button to proceed
  • Setting Start Times
    Press the button until the icon is displayed. The start time will be displayed flashing, along with the program letter (A, B, or C) and the start time number (1, 2, 3, or 4)
  • Setting Run Times
  • Station Repeats
    A common reason for a controller to repeat a cycle is too many programmed start times. Only one start time per active program is required, a second start time will cycle the
  • Setting Watering Days
    The controller displays currently programmed active day schedule information. You can choose to water on specific days of the week, or you can choose interval watering, or choose
  • Sensor Operation
    The NODE is compatible with the Hunter Clik rain sensors including Mini-Clik® and Rain-Clik®, as well as many other interrupt type devices/sensors that do not require power. Simply
  • Seasonal Adjustment
    Press the button until the % is displayed. Press the plus (+) or minus (-) button to increase or decrease the seasonal adjustment value from the default 100% (down to a
  • Manual Watering
    Manual Watering allows the user to activate a single station for a specified run time or activate an entire program. The weather sensor condition (if used) will be disregarded in
  • Turning the System Off
    To turn your controller off, press the button until the icon and Off is displayed on screen. After a short period of time the display will shut off to retain battery power. To
  • Test Operation
    The NODE allows the user a simplified method for running a test program. This feature will operate each station in numerical sequence, from lowest to the highest.
  • Sensor Bypass
    All advanced programming functions are initiated from the Idle Mode, which shows the time, day of the week, and battery life indicator on the display. If something is flashing on
  • Easy Retrieve Memory
    This function allows the user to save a preferred program to permanent memory in the controller, to be restored at any time. This is a great way to override changes made, and
  • Setting Master Valve Operation
    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
  • Programmable Off
    This feature permits the user to stop all programmed watering for the designated period from 1-99 days. At the end of the programmable off period the controller will resume normal
  • Hunter Quick Check
    This circuit diagnostic procedure can quickly identify “shorts” commonly caused by faulty solenoids or when bare common wire touches a bare station control wire. To initiate the
  • Resetting Controller
    Resetting the controller will erase the current program data and restart the controller. A reset does not, however, delete a program saved to permanent memory using the Easy
  • Battery Life
    The remaining battery life can be estimated from the battery life indicator shown on the display. The NODE can operate using either a single 9-volt battery or using two 9-volt
  • Compatible DC Solenoids
    Hunter prefers the use of Hunter valves with a Hunter DC-latching solenoids (P/N #458200) for best performance, however, existing irrigation systems can be retrofitted with another
  • Type of Solenoids
    A battery-operated controller sends a quick DC pulse to operate the solenoid, therefore the battery-operated controller requires a DC latching solenoid to operate correctly. Also,
  • NODE vs. SVC
