ACC has the ability to work in standalone mode with the
Solar-Sync Sensor. This requires facepack version 5.0 or
later, and will also require a Solar-Sync compatible Master
Module (version 5.0 or later).
ACC only requires the Solar-Sync sensor. It does not use
the Solar-Sync Module. The Module functions are part of
the new ACC facepack firmware.
Solar-Sync uses solar and temperature data from the
sensor to change the Seasonal Adjust settings for each
ACC program. You may choose which programs are
adjusted by Solar Sync, and which are left alone.
YOU choose the base run times for the hottest time of the
irrigation season.
ACC Solar-Sync adjusts those times for the actual
conditions, as detected by the sensor.
Solar Sync adjusts every midnight, based on the last 3
days average ET (evapo-transpiration).
The Solar-Sync option does not interact with central
systems and is designed for standalone operation of
a single ACC controller. Do not connect multiple ACC
controllers to a single Solar-Sync sensor.
PrePArAtIOn
Facepack Version
The ACC facepack must be updated to version 5.0 or
later. To check the Version number, turn the ACC dial to
the Advanced Features dial position. Press and hold the
Information button, and see the Revision number.
• Facepack updates may be obtained from the
Resources section of the Hunter Industries web site
(www.hunterindustries.com).

Master Module
The Master Module (part 572000) must be version 5.0 or
later to be Solar-Sync compatible.
• To check the master module version, turn the dial
to the Advanced Features position. Select Utility
Functions, then select View Firmware Versions. The
master module version number will appear in the list
of Module Versions found in the controller.
• Master Modules version 4 and later are "ET Ready",
meaning they will accept input from an ET Sensor for
use within a central system. However, they must be
updated to version 5 or later to operate with
Solar-Sync.
• When new, a Master Module will ship with a
Solar-Sync compatible sticker, if it is Solar-Sync
ready.
• If the Master Module is not "ET Ready", the value for
ET will read, "Not Supported".
• If the Master Module is "ET Ready" but the ET feature
is not enabled, the value will read, "Not Used".
• If either ET or Solar-Sync options are enabled, the
correct sensor type will be shown.
• The Solar-Sync compatible master modules were not
available before November, 2009.
• Master Modules cannot be updated in the field.
Contact Hunter Technical Support if Solar-Sync is
desired for use with an older ACC controller. The
master module is easy to replace, and this will be
required to update to the Solar-Sync version.
• Sensor version numbers will also be shown if the
S-Sync option has been enabled, the sensor is
installed, and communications has been established.
Base Run Times
Program the ACC controller as specified in the Owners
Manual for your controller. When setting station run times,
enter the time that would normally be programmed during
the peak summer watering season. The Solar-Sync is
designed to adjust all run times daily based upon on-site
weather conditions. This is done through the seasonal
adjustment feature on your controller. It is recommended
that all programming be conducted with the controller
Seasonal Adjustment set at 100%.
