CONNECTING THE BATTERY/BATTERIES

The NODE uses one or two standard nine-volt batteries (not included) to operate the valves and program the controller. The controller can operate using either a single nine-volt battery or using two nine-volt batteries. Under normal conditions, the expected life is one year for a single battery and two years when using two nine-volt batteries.

NOTE: The NODE has non-volatile memory. This allows the battery to be removed without losing program information.

To Install the Battery/Batteries

1. Unscrew the rear body of the NODE body to gain access to the battery compartment.
2. Insert the battery/batteries into the battery tray and connect to the controller using the battery connector.
3. Make sure that no water is inside the battery compartment.
4. Screw the NODE rear body back onto the front half.

NOTE: Verify that the seal marker on the rear half of the NODE lines up with the front half, ensuring that a proper seal is created.

ATTACHING SOLENOIDS

The NODE-100 is provided with a solenoid attached to the controller. The NODE-100-LS does not include a solenoid. The NODE-200, NODE-400, and NODE-600 multi-station controllers will operate up to two, four, or six solenoids, respectively. Hunter DC-latching solenoids (P/N 458200) can easily be installed on all Hunter plastic valves.

NOTE: Use DC latching solenoids operating between 9-11 VDC. 24 VAC solenoids will not operate with the NODE.

To Wire DC Solenoids to the NODE

1. Attach the black leads from each solenoid to the single common wire (black lead) coming from the NODE. Secure all wire connections with waterproof connectors.
2. Attach one red wire from each solenoid to the corresponding station wire (red lead) from the NODE. The station numbers are identified on the face of the NODE. Secure all wire connections with waterproof connectors.

NOTE: The maximum wire distance between the solenoid and NODE is 100' (30 m) using 18 AWG (1 mm) minimum wire size.

MOUNTING THE NODE

The NODE can easily be mounted on any Hunter plastic valve. A specially designed valve mounting clip makes installation a snap. A protective rubber cover is provided to prevent dirt from accumulating on the face of the NODE.

To Mount the NODE to a Valve

1. Screw the Hunter DC latching solenoid (P/N 458200) into the valve bonnet.
2. Set the small open end of the NODE holder on top of the solenoid.
3. Set the NODE controller into the large open end of the NODE holder.

CONNECTING A WEATHER SENSOR

A Hunter Mini-Clik^® or Wired 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 Wired Rain Sensor is interrupting the watering, the display will show the System Off icon , "OFF" and on the display.

1. Cut the yellow wire loop attached to the NODE at approximately the middle of the loop.
2. Remove approximately ½" (13 mm) of insulation from each wire. Attach one yellow wire to each of the wires of the weather sensor. You can mount the rain sensor up to 100 ft (30 m) from the NODE controller (18 AWG/1 mm minimum wire size).
3. Secure wire connections with waterproof connectors.

4. To reactivate the weather sensor, press and hold the button until the icon is displayed. Press the button to return to normal sensor mode.

Easy Retrieve Memory

This function allows the user to save a preferred program to permanent memory in the controller, which can be restored at any time. This is a great way to override changes made, and revert back to the original programming schedule.

To save a program:

1. Make sure that the controller is programmed with the preferred programming schedule.
2. From idle mode, press and hold the and button for five seconds to save the current program.
3. The screen will show three dashed lines moving from left to right to indicate the current program is being saved to permanent memory. The display will flash DONE when the process is complete.

To retrieve a saved program:

1. From idle mode, press and hold the and button for five seconds.
2. The screen will show three dashed lines moving from right to left to indicate the preferred program is being retrieved from memory.

The controller now has the preferred program as the current program. The display will flash DONE when the process is complete.

NOTE: Be careful when using Easy Retrieve memory. Saving program data to memory using Easy Retrieve will take the current program information and override whatever is saved in permanent memory. When saving program data, make sure that the current program data is what you want saved.

Setting Master Valve Operation (NODE-200, NODE-400, & NODE-600 Only)

The multi-station NODE models (NODE-200, NODE-400, and NODE-600) can be 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.

1. From the idle mode, press the button until the icon is displayed.
2. Program A will be displayed along with the active station number on the lower left. Make sure the active station showing is "1." The run time will be shown.
   
3. Press the 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.
   
4. 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.

Programmable Off (Up to 99 Days)

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 operation.

1. From idle mode, press the button until the icon is displayed. Wait two seconds until OFF is shown on the display. The controller is now in System Off mode.
2. Press the button and a blinking "1" will be displayed, indicating the number of days the controller will stay off. Program the off days as desired, up to 99 days maximum.
3. The display will show the number of days remaining in the OFF period.
4. To interrupt the OFF period, press the button to return to the idle mode screen, showing the time of day and day of the week.

BATTERY-LIFE INDICATOR

The remaining battery life can be estimated from the battery-life indicator shown on the display. The NODE can operate using either a single nine-volt battery or using two nine-volt batteries. Using two nine-volt batteries will yield approximately twice the battery life of a single nine-volt battery. The battery-life indicator chart below shows an estimate on the remaining battery life.

Full: 100–60% remaining battery life
Med: 60–25% remaining battery life
Low: 25–0% remaining battery life
Replace battery immediately!

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 Retrieve memory feature to save a preferred program.

1. From idle mode, press and hold the , , and keys.
2. After two seconds the screen will go blank. Continue to hold the , , and keys.
3. 12:00 will flash on the display. Release the keys.
