INTRODUCTION

The Solar Sync is a sensor system that, when connected to a
compatible Hunter controller, will automatically adjust your
controller watering based upon changes in local climate conditions.
The Solar Sync utilizes a solar and temperature sensor to measure
on-site weather conditions used to determine evapotranspiration
(ET), or the rate at which plants and turf use water. In addition, Solar
Sync includes a Hunter Rain-Clik™ and Freeze-Clik™ sensor that
will shut down your irrigation system when it rains and/or during
freezing conditions.

A small module connects the sensor to the controller and will
automatically increase or decrease watering run times based on
changes in weather. The result is a new water-efficient irrigation
product that promotes water conservation and healthier plants.
You simply program your controller like you normally would, and
the Solar Sync takes over from there, eliminating the need to
manually adjust your watering schedule.

SYSTEM OVERVIEW AND OPERATION

The Wireless Solar Sync System is simply and easily installed on any compatible Hunter Irrigation controller (see Owner’s Manual to verify
compatibility). The Wireless Solar Sync Sensor measures solar radiation and temperature and calculates the daily evapotranspiration (ET)
factor for irrigation. This represents the amount of water lost by the plants due to local climate conditions, which needs to be replaced by
irrigation. The Wireless Solar Sync also includes Hunter Rain-Clik™ and Freeze-Clik® sensors that will automatically shut down the irrigation
system during rain events or freezing conditions.

Enter a mid summer watering program in your controller per the programming instructions in the Owner’s Manual provided with your
controller. The Wireless Solar Sync Sensor sends weather data and applies it daily to the controller’s water schedule by adjusting the
controller through the seasonal adjust feature.

This Owner’s Manual applies to the following kits:

• WSS: Wireless Solar Sync kit for Hunter Pro-C, PCC, ICC, and I-Core controllers

• WSSSEN*: Wireless Solar Sync kit for Hunter ACC and X-Core controllers

* Note that WSSSEN does not include the Solar Sync Module. The ACC and X-Core controllers have the Solar Sync software built in and do

not require the Solar Sync Module. Therefore, the WSSSEN should be used with the ACC and X-Core Controllers.

SENSOR DETAILS

Installing the Sensor

Using the screws provided, mount the Solar Sync sensor on any
surface where it will be exposed to unobstructed sun and rainfall,
but not in the path of sprinkler spray. The sensor needs to be
oriented upright and the swivel bracket can be moved for mounting
on angled surfaces. Loosen the locknut and screw before swiveling
the bracket and then retighten.

Note:

The Wireless Solar Sync Sensor is designed

to operate to a maximum distance of 800 feet
(228 m) from the Wireless Receiver.

Note:

Place Solar Sync where it can receive full sun.

The Sensor Gutter Mount can also be used as an optional mounting
method. The Sensor Gutter Mount (SGM) allows the Sensor to be
mounted directly to the edge of a gutter. Install the SGM on the
Sensor by removing the extension arm supplied with your Sensor
and reinstalling SGM in its place. Position the SGM on the edge of
the gutter and secure by twisting the thumb screw.

SENSOR DETAILS

Clik Operation

The Rain-Clik™ will keep the irrigation
from starting or continuing during
rainfall. No adjustment or calibration
is required for the Rain-Clik™ sensor.
The Rain-Clik™ uses patented Quick
Response™ technology that will shut
the system off during the first few
minutes of rain. The only adjustment
that is necessary is the vent ring that
will either slow down or speed up the
time at which the sensor dries out and
the system is turned back on. Opening the vent will speed up the
dry out time and closing the vents will slow down dry out time.

In addition, the Solar Sync’s built-in temperature sensor provides
system shutdown when freezing conditions occur. At approximately
37˚ F/3˚ C and below the Solar Sync module will command the
controller to shut down. A “sensor off” indication will be displayed
on your controller when the sensor is active. When temperatures
rise above 37˚ F/3˚ C, automatic irrigation will be activated at the
next scheduled start time.

Maintaining the Sensor

The Solar Sync sensor is designed for outdoor use, but must be
kept clean to function correctly. Wiping the clear dome covering the
solar radiation sensor every 6 months is recommended. Do not use
harsh chemicals or abrasives on the clear dome.

CONNECTING TO THE CONTROLLER

Installing and Wiring the Module

Begin by activating the CR2032 backup battery (used for date/
time backup in the event of a power outage) by pulling the battery
insulator at the bottom of the module. The expected battery
life is ten years. If the battery requires replacement, the battery
compartment is located on the back of the Solar Sync module.
Remove the cover and install the battery with the positive side (+)
of the battery visible, facing toward you. Replace the battery cover.
Replace battery with CR2032 type battery only. Use of another
battery may present a risk of fire or explosion.

Note:

Battery may explode if mistreated. Do not

recharge, disassemble or dispose of in fire.

The Solar Sync module
is designed to be
wall-mounted next to the
irrigation controller. A
rubber cover is provided
for outdoor installations
to protect the module
from the weather. Use two
anchors or self-tapping
screws to secure the
module to the wall.
Place the rubber cover
mounting tab behind the
module before screwing
the module to the wall.

Note:

If you are installing Solar Sync on an ACC or

X-Core Controller, the Solar Sync Module is not required.
For the ACC or X-Core controllers, the WSSSEN kit should
be used, as it does not include the Module. (See the
controller‘s owner‘s manual for more details.)
