The RM-2 Rainmaker irrigation controller provides a solution for large scale irrigation applications.
Providing both remote connectivity and water balance control, the RM-2 is a very powerful and scalable irrigation controller.The RM-2 comes with both an Ethernet and an integrated 3G modem providing remote access via your smart phone, tablet, PC or centralised monitoring system. The unit is congured using its own web interface, enabling the user to setup watering stations and program times.

Main Benefits:

  • 25% – 40% Savings with Water Balance control
  • Remote Monitoring using PC, Smartphones and Tablets over GPRS,3G Wi-Fi, Radio &
  • Satellite
  • Water Balance & Timed irrigation
  • Decoders proven in nearly 500,000 stations over 15 years Centralised control will work
  • with most SCADA Systems Multi language support
  • Upto 508 Decoder stations


  • Uses Gold Standard Irrigation Method – Water Balance Built in Hydrozone calculator
  • Optional Flow, Pressure and Moisture Monitoring Water Budget control
  • Email & Text Alarms
  • Provision for Fertigation
  • Daily Automatic adjustment of watering times based on just two parameters

Market Sectors

  • Agriculture
  • Irrigation
  • Large Scale City Watering
  • Golf Irrigation



The RM2 is microprocessor based RTU equipment with robust modular construction. The RM2 works on ‘two wire path’ system and each BT2 can carry up to 63 stations
( 2 wire decoders ).
The base model which consists of two numbers of BT2 can operate 10 Decoders simultaneously if all conditions permit

Additional BT2/Tbox may be added in the main controller enclosure, up to 4.

Web Page Configuration

The RM-2 has an integrated web server allowing users to congure the RM-2 using a standard web browser.
This means it does need not to rely on a 3rd party server, with its associated additional fees.

The web interface will display historic alarms and the current status of each watering station. The web interface allows the user to test individual or groups of stations by using the manual override feature. This is very useful during the commissioning phase of the project.
