The Remconix Irrigation Controller (RICO 24S) is a standalone wireless irrigation controller, allowing control of up to 24 zones. It is a powerful and easy to use device, easy to program. In one glance you can see which program is running, which zones are currently operating and the amount of watering time left for each zone.

The RICO 24S also has a receiver on board and in conjunction with a Field Sensor Transmitter (FST) you can easily add a wireless rain sensor. The RICO 24S acts as the base transmitter unit and must be used in conjunction with Remconix Valve Control Units (VCU) for a complete wireless irrigation solution.

Main Features

  • 3 independent programs ( A,B,C) , 4 start cycles per program, each program capable of running at same time as another.
  • Wireless control of up to 24 zones.
  • Zone timing from 1 minute to 16 hours.
  • Wireless control of one pump or Master Valve.
  • Wireless Rain sensor.
  • Rain Delay inhibit from 1 to 7 days.
  • Schedules by day of week, intervals or odd/even day.
  • Manual zone operation or whole program operation.
  • Unique Factory Encoding allows different RICO24 systems to operate within range of each other.
  • Learn Mode – Utilises a very simple technique to “marry” together the RICO 24S and VCUs without any setting of switches. Allows easy replacement of a VCU should the need arise.
  • Range Test Mode – The RICO 24S can be easily placed into Range Test mode allowing the installer to test reception on the Valve Control Unit (VCU) in the field.


The Irrigation Control Interface (ICI) is an addition to a standard irrigation controller. The device offers wireless control of up to 12 zones plus an additional pump start unit. The ICI’s inputs are simply connected to the outputs of the irrigation controller.

The ICI monitors the signal levels and uses radio signaling to communicate changes to Valve Control Units (VCUs) in the field. The VCUs then open or close the appropriate solenoid valve according to the signal received.

Main Features

  • Wireless control of up to 12 zones plus a remote Pump Control Unit (PCU) or Master Valve.
    For control of > 12 zones several ICIs can be combined together.
  • Digitally encoded signal with multiple burst transmission is used to ensure signal integrity.
  • Unique Factory Encoding – Each ICI is uniquely encoded at the factory to ensure that only the required VCUs and PCU are activated i.e. prevents interaction with neighbouring systems.
  • Learn Mode – Utilises a very simple technique to “marry” together the ICI and VCUs without any setting of switches. Allows easy replacement of a VCU should the need arise.
  • Range Test Mode – The ICI can be easily placed into Range Test mode allowing the installer to test reception on the Valve Control Unit (VCU) in the field.
  • Simple LED indications are given indicating the current status of the system.
  • Irrigation Scheduling is set on the 3rd-party irrigation controller – the ICI simply acts as a transparent wireless link.
  • Signal Range can be extended with the use of a Remconix Repeater unit.


The Remconix Irrigation Controller (RICO) is a wireless irrigation controller, allowing control of either 16 or 48 zones. It is a powerful and easy to use device and is recommended for users with access to a computer on which the RICO16/48 scheduling software is run. Once the schedules are set up on the PC they are downloaded into memory on the RICO and the unit is then capable of running completely in standalone mode without the need of a connection to the PC. While the PC remains connected the screen is updated with feedback information allowing the operator to see at a glance which irrigation programs are running, which zones are currently operating and the amount of watering time left for each zone. The RICO acts as the base transmitter unit and must be used in conjunction with Remconix Valve Control Units and/or Pump Control Units for a complete wireless irrigation solution.

Main Features

  • RICO 48 - 10 independent programs, 10 start cycles per program, each program capable of running at same time as another.
  • RICO 16 - 5 independent programs, 6 start cycles per program, each program capable of running at same time as another.
  • RICO 48 - Wireless control of up to 48 zones.
  • RICO 16 - Wireless control of up to 16 zones.
  • RICO unit can run standalone without a PC connection.
  • Zone timing from 1 minute to 15 hours.
  • RICO 48 - Each zone can be set to automatically start up to 10 different pumps or Master Valves.
  • RICO 16 - Each zone can be set to automatically start up to 3 different pumps or Master Valves.
  • Zone Re-Sequencing – the irrigation sequence order can be changed easily per program using drag and drop.
  • Zone linking – several zones in a program can be linked to operate simultaneously.
  • Seasonal Adjustment of timing from 10% to 200%.
  • Rain Delay inhibit from 1 to 7 days (operated either from PC or unit keypad).
  • Schedules by day of week, intervals or odd/even day.
  • Manual zone operation or whole program operation.
  • Zones can be set up to control pumps, flush filters, fountains etc.
  • Each zone can be given a meaningful name instead of operating purely by zone number.
  • Unique Factory Encoding allows different RICO systems to operate within range of each other.
  • Step by step installation guide running on PC makes installation easy.

The Valve Control Unit - 4Z and 2Z (4 zone & 2 zone) is a wireless irrigation receiver. It is used in conjunction with a Remconix ICI or RICO transmitter to provide a complete wireless switching system for irrigation valve control. The VCU receives instructions from the transmitter and activates up to 4 D.C. latching solenoids. The VCU-4Z has the same functionality as the VCU Mkii, but is fully IP68 compliant i.e. the unit is completely sealed against ingress of water and dust, so can be placed inside a valve box without fear of damage due to flooding.

Main Features

  • IP68 compliant - fully sealed against water and dust ingress.
  • Control up to 4 D.C. latching solenoids.
  • Highly sensitive micro-controlled receiver with built-in error correction.
  • Solenoid switching time < 1 second from receipt of signal.
  • Valve Test Mode – Valves can be operated from the VCU itself without the need to operate the transmitter.
  • Auto Learn Mode – The VCU learns the unique ID of the transmitter without having to set any DIP switches.
  • Range Test Feature – Each time the transmitter sends a Range Test command the VCU responds by flashing an LED indicator.
  • No external programming/test equipment required.
  • Pump/Utility Control – Control pumps and other utilities by connecting external latching relays to the VCU outputs in place of solenoids.
  • Field-configurable as a Master Valve controller.
  • Automatic shutoff period of 9 minutes to avoid over-watering in unlikely event of signal failure.
  • Battery operating life > 1 year under typical usage conditions.(Note 1)
  • LED indications for Battery Low, Valve Test Mode, Learn Mode, Valve Status and Range Test.


The Tank Level Controller (TLC) uses sensor inputs to monitor the level in a water tank or dam. When the water level changes the TLC sends a radio control signal to the Pump Control Unit (PCU) to switch the pump on or off.

The TLC is normally powered by long-life lithium batteries but can optionally be supplied from an external 12V supply if available.

The unit can be used either with a float switch or with up to 4 different level probes. When operated with multiple probes the TLC is capable of switching a total of 4 pumps – one pump per level probe.

The TLC has a standard BNC antenna connector to which a rubber-duck antenna is fitted as standard. For longer range applications this may be replaced with an external dipole or directional antenna.

Main Features

  • Automatic wireless control of up to 4 different pumps when used with level probes.
  • Automatic wireless control of a single pump when used with a float switch.
  • Manual override allows remote pumps to be controlled by simple keypresses on the keypad. Manual mode overrides automatic mode allowing convenient maintenance of your system.
  • Digitally encoded signal with multiple burst transmission is used to ensure signal integrity.
  • Unique Factory Encoding – Each TLC is uniquely encoded at the factory to ensure that only the required Pump Contol Unit is activated i.e. prevents interaction with neighbouring systems.
  • Learn Mode – Utilises a very simple technique to “marry” together the TLC and Pump Control Units (PCU) without any setting of switches. Allows easy replacement of a PCU should the need arise.
  • Range Test Mode – The TLC can be easily placed into Range Test mode allowing the installer to test reception on the Pump Control Unit in the field.
  • Simple LED indications are given indicating the current status of each pump.


The Pump Control Unit(PCU) is a wireless receiver capable of switching a high current output, typically used to activate a contact breaker circuit to start or stop a pump. It is used in conjunction with a Remconix ICI or RICO transmitter to provide a complete wireless switching system for irrigation valve control. It can also be used with up to 5 Remconix Tank Level Controllers (TLC) to allow remote automatic level control for water tanks or dams.

The PCU receives instructions from the transmitter and activates an internal solid state relay switch in order to control the external equipment.

The PCU can also be manually controlled by pressing the On/Off button on the keypad.
The PCU has a standard BNC antenna connector to which a rubber-duck antenna is fitted as standard. For longer-range applications this may be replaced with an external dipole or directional antenna.

Main Features

  • Internal solid state relay capable of switching 10 Amps maximum through to the external equipment e.g. 3-phase contact breaker.
  • Manual Switching – The pump can be operated from the PCU itself without the need to operate the transmitter.
  • Highly sensitive micro-controlled receiver with built-in error correction.
  • Built-in surge protection provides protection against transient voltage spikes on the power supply.
  • Auto Learn Mode – The PCU learns the unique ID of the transmitter without having to set any DIP switches.
  • Range Test Feature – Each time the transmitter sends a Range Test command the PCU responds by flashing a the Range Test LED indicator.
  • Automatic shutoff period of 9 minutes as safety feature unlikely event of signal failure.
  • LED indications for Learn Mode, Output Status and Range Test.


The Repeater Unit can be used to extend the transmission range of any of the transmitter units in the Remconix range. This includes the Irrigation Control Interface (ICI), the Remconix Irrigation Controller (RICO) and the Tank Level Controller (TLC). It is normally powered from 2 long-life lithium batteries allowing it to be positioned optimally even where there is no mains power available. In situations where mains power is available the unit can be supplied using an external 12V d.c. transformer.

A single repeater can be configured to operate with multiple transmitters, for example it could be used to forward signals from an Irrigation Control Interface and a Tank Level Controller to a Pump Control Unit that is located behind an obstruction. A maximum of 2 repeaters can be used in any one system, and these cannot be daisy-chained together. Also, if using 2 repeaters in one system you must ensure that one repeater has an even numbered serial number and the other is an odd-numbered serial number.

Main Features

  • Highly sensitive micro-controlled receiver with built-in error correction.
  • Auto Learn Mode – The Repeater learns the unique ID of the transmitter units without having to set any DIP switches.
  • Digitally encoded signal with multiple burst transmission is used to ensure signal integrity.
  • Range Test Mode – The Repeater can send a burst of range test signals during installation to assist with optimal choice of location.
  • Range Test Indication – The Repeater gives a visual indication each time it receives a Range Test signal from a transmitter.
  • Battery operating life > 1 year under typical usage conditions.(1)
  • Visual indication for Battery Low.
