The ACC-COM-LAN Com module is an Ethernet modem and communications manager. It will contain the controller’s unique identification (address), and enables communications into and out of the controller when combined with other devices. ACC-COM-LAN contains an Ethernet modem, and requires a fixed (static) IP address in addition to the controller address. The fixed IP address must be accessible from the IMMS computer. Please contact your local network administrator for your specific network details. The ACC-COM-LAN may also communicate with other controllers, via optional UHF radio modules (sold separately) with an antenna for wireless communications, and/or an ACC-HWIM hardware interface module (sold separately) for hardwired communications over Hunter GCBL cable. The other controllers will not have an IP address, and will use the controller address only for hardwire and radio communications.

IMMS software and hardware have been intensively developed and refined into a graphically based irrigation command and control program. With IMMS, interactive map graphics (to station level) put the irrigation system manager in complete visual control of wide-area watering operations. An optional ET software add-on provides complete weather-based irrigation with station level soil moisture modeling, using inexpensive local ET sensors. IMMS has a full range of communications options, including Ethernet, GPRS mobile, dial-up telephone, UHF radio, and hardwired cable. IMMS is a Windows-based application that is compatible with Windows XP, Vista, and Windows 7 and 8.

Hunter has designed IMMS central control to communicate as simply and reliably as possible, through a host of available technologies. Let our specialists fit a system to your needs and avail-able infrastructure, to achieve total control at the lowest possible cost. IMMS may be sub-divided into Sites, which are clusters of controllers within easy “talking distance” of one another. You can reach a distant Site with one form of communications, and then share that connection with other controllers in the area using different options. Low-cost, high performance ET, flow, and weather sensors share the controller network to add water savings and performance visibility to IMMS. Full two-way communications with all controllers ensures reliable operation, rapid alarm notification, and complete reporting capabilities, wherever your irrigation is located.


The IMMS graphics update includes the ability to create one or more map views for control purposes. You can see where all of your irrigated locations are, and click any for a more detailed view or control purposes. Ideal for orienting new employees, IMMS Graphics also simplifies life for busy irrigators with large numbers of assets to control. Use any background image to show the system, site, or controller area, and create control zones and station symbols that link to their command functions. You supply the pictures, and IMMS includes all the tools you need to create an interactive map-based system.

Flow Monitoring

Track your water usage, and spot plumbing problems a mile away (or several hundred miles away). IMMS is built around the powerful ACC controller platform, which includes real-time flow monitoring. With a flow meter and normally-closed master valves, the ACC detects incorrect flow conditions and moves swiftly to isolate the offending valves. Each flow violation is reported to the central software, after the controller has finished its own diagnostics. Leaks, breaks, and flooding are minimized, and the irrigation manager is the first to know of any issues. IMMS also tracks total water usage by site, controller, program, and station. Keep detailed historical records, and go home each day with the peace of mind given by automatic flow monitoring.

Alarm Management

IMMS reports all alarms, including over-currents, flow violations, communication issues, and water window violations, with individual date- and time-stamped messages. The IMMS operator knows the state of all irrigation controllers and valves at a glance, without driving around town to check individual sites. Printable reports can be exported to other formats or handed to work crews for investigation.


Each controller has its own complete setup and operations screens. Eliminate the confusion and hassle of multiple field personnel setting up irrigation with dials and buttons. Shut off irrigation with a mouse click for emergencies. Access every function of controllers from simple spreadsheets or choosing from a menu of common functions and commands.

IMMS-ET (Evapotranspiration)

The optional IMMS-ET software add-on uses cost-effective local sensors, combined with your station database to create water-saving irrigation programs for your whole system, every day. IMMS-ET models the moisture level in soil reservoirs (including compensation for natural rainfall) and schedules just enough irrigation to replace what your plants need. IMMS-ET can track climate history according to your own sensors and document how it has responded with irrigation adjustments.

Key Specifications

  • Operating system: Microsoft XP, Vista, Windows 7, or Windows 8 (32 or 64 bit)
  • Minimum RAM: 512 MB
  • Minimum screen resolution: 1024 x 768
  • Storage: At least 100 MB disk space
  • Compatible Controllers

  • IMMS is optimized for the Hunter ACC controller and accessories (including decoder controllers).
  • Compatible Sensors

  • Hunter Flow-Sync sensor for ACC controllers (one per controller). Provides flow total reporting and flow alarm monitoring with diagnostic shutdowns in real time.
  • Each controller should have its own rain sensor for fast rain shutdowns. All Hunter Clik sensors are compatible with ACC.
  • ET Sensor platform is for use with IMMS-ET software. ET Sensor is added to selected ACC controllers, to report local conditions. This local ET data has no additional monthly charges and can be shared through the software to create schedules for other controllers in the same micro-climate. Add as many ET Sensors as needed to sample all micro-climates.
  • Solar Sync Sensor (wired or wireless): Each controller requires its own SOLARSYNCSEN or WSS-SEN for smart, water-saving self-adjustment. Solar Sync sensors also provide rain and freeze shutoff functions. Solar Sync compatibility is included with the basic IMMS4CD software.
  • Communications Components

  • ACC: Communications options are installed inside the ACC controller cabinet. No additional enclosures or power are necessary for these options.
  • Options include radio, hardwire, dial-up, Ethernet, and GPRS mobile communications.
