MODELS – COMMUNICATIONS
Modules (for ACC controllers)
Each ACC controller can accept one Communications module, plus hardwire interface terminal and/or UHF radio as required. All communications components are installed internally in the ACC except antennas.
ACC-COM-HWR – Hardwire/Radio only (in or out)
ACC-COM-POTS – Dial Up Telephone from PC (also enables hardwire/radio out)
ACC-COM-GSM – GSM Cellular from PC (also enables hardwire/radio out). –E version for International. SIM not included.
ACC-HWIM – Hardwire Interface Module (provides hardwire connections for GCBL cable)
RAD3 – UHF Radio module – license required, antenna not included. Not available in all markets.

MODELS – Communications
Interfaces and Accessories (for ICC, Pro-C, SRC controllers)
Other Hunter SmartPort compatible controllers can be IMMS connected with these external cabinets and accessories.
IMMS-SI-HW – Hardwire Site Interface (use also for GSM communications), -E for international
IMMS-SI-MOD – Dial Up Telephone Site Interface, -E for international
IMMS-CELL-GSM – GSM Cellular IMMS-SI-HW. E version for International. SIM not included.
IMMS-CI-HW – Controller Interface for additional controllers on site. E version for International.
IMMS-R – UHF Radio for all Site/Controller Interfaces, license required. Not available in all markets.

DIMENSIONS
IMMS-SI cabinets (all): 16" H x 11.5" W x 4.25" D (400mm H x 292mm W x 108mm D)
IMMS-CI cabinets (all): 8.9" H x 9.9" W x 4.3" D (226 H x 251mm W x 109mm D)
All other devices are internal to the controllers or interface cabinets.

ELECTRICAL SPECIFICATIONS
(IMMS Site Interface and Controller Interface cabinets require a separate primary AC power connection)
IMMS-SI, US/E versions: ~120V .5 A/240V .25A
IMMS-CI, US/E versions: 120V .5 A/240V, .25A

SPECIFICATIONS AND FEATURES
• Locations, controllers and stations can be userassigned actual names and site descriptions for easy reference, and download to ACC controllers.
• Built-in calendar program allows for scheduling of maintenance events (mowing, fertilizing, etc.).
• Extensive standardized reporting section allows generation of graphs showing estimated water usage and dollar costs. Data can be viewed for current and historic time periods to ascertain trends.
• ACC controllers may also be retrieved and saved from the field to the central computer.

CONTROL CAPABILITIES
• Manage irrigation systems at up to 100 different sites from a single central computer.
• Each site managed can have up to 100 controllers connected to the Site Interface, or Master Controller (ACC). The IMMS™ system can network with Hunter ACC, ICC, Pro-C, and SRC controllers.
• ACC controllers are organized on different Sites from the Site Interface/Controller Interface connected controllers, and can coexist within the same software system.
• Manage all controller programming data from the central computer.
• Manual functions: activate, deactivate manual or automatic waterings from the central computer.
• Initiate rain-off or rain-delay features by controller or globally.
• Manage “no water days” and “non water windows” (ACC only) globally, by site, or by controller. This allows an irrigation manager to set specific days for maintenance, events, etc.
• Easily program cycle and soak waterings for maximum water efficiency
• Manages watering windows and no-water days with global and site specific settings.

MONITORING CAPABILITIES
• Monitor rain, wind and freeze sensors for real-time responses to weather conditions.
• Monitor, retrieve, and report actual flow and usage (ACC controllers with HFS flow sensors)
• Read system flow conditions through optional Flow-Clik flow sensors.
• This will shut specific zones down during over-flow conditions (line breaks, broken sprinklers), saving water and reducing liability concerns.

COMMUNICATIONS CAPABILITIES
• IMMS 2.0 can operate as an on-site hardwired central system, directly connected to a network of up to 100 irrigation controllers via the site and controller interfaces or Master Controller. IMMS 2.0 can also operate as a wide-area network via telephone modem to multiple sites (up to 100), each with multiple controllers (up to 100 controllers per site!).
• Hardwire, dial-up, cellular GSM, and UHF radio communications for lowest cost communications to fit most needs.
• ICR compatible for wireless remote control.
• Radio-equipped ACC controllers also respond to UHF Maintenance Radio remote control.
