Introduction

The Micro-Master Touch Irrigation Controller is the latest in a long line of reliable Australian designed
and built controllers brought to you by Toro. It uses the latest in microprocessor technology, including
a full colour, touch screen LCD display.
Each controller consists of a Master Unit, and up to 4 Remote Units.
The Master Unit is supplied with one 8 Station Module, and can be expanded with 8 Station Modules
up to a total of 32 Stations.
Remote Units are supplied with one 8 Station Module, and can be expanded with 8 Station Modules
up to a total of 32 Stations.
It is not necessary to expand each unit before another Remote Unit is added to the controller. Since
each Remote Unit has it's own power supply and is physically separate from the Master Unit, Remote
Units can be placed in different locations to the Master Unit. For example, the Master Unit could be
located in the main office, and an Expansion Unit could be located in the pump shed, and used to
control the pumps, filters and chemical injection system.

Controller Capabilites

The Micro-Master Touch controller supports various expansion and communication cards.
Expansion Modules include 8 station modules, digital input modules, and analogue input modules.
Communication cards include RS232 modules, Analogue/GSM/GPRS Modem interface modules,
RS485 modules, USB modules, and Ethernet interface cards.
Each Micro-Master Touch controller can be expanded out to 160 stations using additional Remote
controller units (up to 4 units). Communication between units is achieved by RS485 communication
modules or through the addition of the Radio-Master for Touch range of wireless modules.
The Touch Controller supports 32 individual irrigation programs. Each program operates
independently and can be in sequential or grouping mode. Irrigation Programs can be independently
Enabled, (Rain Switched). There are two levels of globally enabling irrigation programs. A global
enable and rain switch stops all idle programs from starting but allows currently active programs to
complete. Individual programs can be set to ignore the rain switch control.
Programs have the following capabilities:
· Irrigation Units can be seconds, minutes or volumetric,
· Chemical Injection Units can be set independently of the main program. Each chemical has it's
own units and may be seconds, minutes, or volumetric.
· 14 day daytable. Each day can have different number of cycles, and include or exclude chemical
injection,
· Up to 8 start times,
· 4 chemicals per group or station,
· Up to 48 groups with up to 40 Stations per group,
· Water budget percentage, 0 to 250%,
· Individual external inputs for starting, stopping, holding and skipping groups/stations,
· Individual Flow Meters for each program, pump, and chemical,
· Staggered programs, where the completion of one program can start another,
· Filter bank support,
· Pump set support.
The chemical system supports up to eight chemicals.
Each chemical has individual prewet/mixing times and can be assigned to any station outputs in the
