1 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.
1.1 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

Micro-Master Touch User Guide

controller.
Any four of the eight chemicals can be associated with each program.
The Filter Bank system supports up to eight separate banks of filters.
Each filter bank may contain up to eight filters, and each filter can be assigned to any station output
in the controller.
The Pump Set system supports up to eight separate sets of pumps.
Each pump set may contain up to four pumps, and each pump can be assigned to any station output
in the controller.
Each pump set supports runtime levelling, priority, and can support a VFD as pump 1.
1.2 Do's & Dont's
The Micro-Master Touch controller will give you many years of faithful service, as do all Micro-Master
products, but there are certain requirements that should be observed when using the controller, as
with all electrical equipment.
·Don't leave the door open when you have finished with the controller. Water entering into the
controller via an open door is not covered by your warranty. A burst pipe in a pump shed, for
example, can do a lot of damage.
·Do ensure that all wiring holes in the case are sealed. Ants, mice and slugs can also destroy the
unit if they are allowed entry and will not be covered by your warranty.
·Don't use metal objects to select icons on the LCD screen. You can destroy the touch pad. A
finger, eraser tipped pencil or wand is all that is needed.
·Don't mount the unit where it is exposed to full sun during the day. Temperatures within the unit
may become excessive causing it to fail. Always supply some shade from the elements.
·Do install a backup battery. This will support the unit during any minor power outages.
·Don't use any chemical products to clean the LCD display. A slightly moist clean cloth is all that is
required to lightly wipe away any marks.
·Do use an earthed power source as this will supply greater protection for the unit.
·Don't open up the 240v AC side of the controller. These voltages can be lethal, particularly
if water has entered the case. Always use a licensed support person or return the unit for repair.
·In areas with known voltage fluctuations, or frequent 'brownouts', we recommend that the controller
be connected to a UPS and surge protection device.

2About This Manual
Digital interactive copies of this manual in various formats are available for download from http://
www.tdssoftware.com.au/manuals/
This manual (in digital form) has been designed to be context sensitive, and includes many topic links
and image hotspots.
Clicking a button in an image will, where possible, cause a jump to the same screen as if the button
were clicked on the physical Touch controller.
Where not possible or appropriate, the hotspot links to a paragraph explaining the purpose of the
button.
Where appropriate, examples in this manual have been drawn from a real world example.
In this example, a treelot is irrigated using recycled water from a storage tank. There are two zones
in the treelot, allocated to Stations 1 and 2, and a flushing valve (station 4) is connected to both
zones to drain solids from the line after irrigation. The treelot irrigation program operates in grouping
mode. The storage tank is circulated with a five minute on, five minute off cycle repeating 6 times
each shift, running four times every day. Two master valves are connected to the irrigation (station
5) and circulation (station 6) mainlines A pump is connected to station 7, an ozone generator is
connected to station 11, and two filters in a single bank are connected to stations 9 and 10. Chemical
injection is performed each treelot irrigation. Three level sensors detect when the tank is empty,
almost full, and full. The empty and full sensors control the treelot irrigation, and the almost full
sensor stops the ozone generator, and stops the circulation program.
A diagram of the real world example is shown below.

4 Installation Instructions
4.1 Wall Mount Installation
On the back of the controller is a “keyhole” shaped mounting slot as well as 2 mounting holes along
the bottom edge. These mounting holes are shown circled red in the next picture. Access to the 2
mounting holes is from the front behind the bottom cover plate.
Figure 4 - Back of Micro-Master Touch Controller
When attaching to wall studs use a No. 10 self tapping screw and leave approx. 6mm of the head
exposed to slip into the “keyhole” slot. To secure and stabilise the controller, drive additional screws
through the bottom mounting holes.
NOTE: When mounting the controller to a sheet metal wall, it is essential to mount timber mounts to
the wall first and then mount the controller to the timber. This prevents high temperatures being
conducted to the controller.
4.2 Module Installation
The Touch controller uses various modules installed into "slots" on both the motherboard and
processor boards to increase its versatility or capacity.
A wide range of modules are available for both the communication slots on the processor board and
expansion slots on the motherboard. Both employ a similar method of mounting and are easy to
install or remove.

Micro-Master Touch User Guide
8
© 2014 Toro Australia Pty Ltd Ver 1.2, June 2014
NOTE: Before any installation or removal of a module occurs, all power to the unit MUST
be removed, including the backup battery. Never install or remove a module with power
applied. Damage to the module may occur and this is NOT covered by your warranty.
NOTE: Two screws are used to provide power and to secure the Expansion Modules. All
screws must be installed for the Expansion Module to operate correctly.
The motherboard, which is at the bottom of the case, holds all of the field wiring modules, along with
a power supply module and Radio-Master for Touch RMT200 module, if fitted.
The Power module (already fitted) and Expansion Slots number 5, 6 & 7 use screws to hold the
module in place and are connected to the controller via 8 pins.
Expansion slots 1 to 4 are for the Station(Valve) relay modules, Analogue Input and Digital Input
modules. Each of these modules is connected to the controller by a 20 way edge connector and held
in place by 2 screws. The screw connection points supply 24V AC and GND to the modules, for the
field wiring. Installing a module in slots 1 to 4 is achieved by inserting the tongue of the expansion
module into the edge connector until the 2 screw holes align and then fitting the screws.
The tongue of the module is the slightly smaller end that has stripes down the edge, on both the top
and bottom sides.
Expansion modules 5 & 6 are fitted on edge. Ensure that all the gold pins enter the header connector
on the module and the screw mount aligns with the bracket, then insert the screw. Typically, this is
where the RS485 modules would reside, when other remote units are connected using wire.
Expansion module 7 requires the pins to come through the board into the header and 4 screws to
hold the module in place.
Remember, no power should be present when installing or removing modules. You may also find a
magnetic screw driver of help when trying to install or remove screws.
The processor (or logic) board is the top board in the controller with the LCD screen attached. This
board has 2 slots on the right hand side for various types of communication modules to be installed.
These modules are shorter than the motherboard expansion modules and should never be
interchanged. The connection of the module is achieved by an edge connector and a single screw to
hold the module in place. Once again, slide the tongue of the module into the edge connector until
the screw hole aligns and then insert the screw.
When you restart the controller, navigate to the Expansion Module Configuration page and initiate a
scan by clicking the scan button.
The controller will perform a scan to determine what modules are fitted to the unit and update its
configuration.
An example of a motherboard is shown in Figure 5. This motherboard has been populated with 2 8
Station Relay Modules (MMTOUCH-STN) in Expansion Module numbers 1 and 2, an RS485 Remote
Expansion Module (MMTOUCH-485E) in Expansion Module number 6 and a Radio-Master for Touch

Radio Expansion Module (RMT200) in Expansion Module number 7.
Figure 5 - Touch Motherboard with 2 MMTOUCH-STN,
RMT200 and MMTOUCH-485E modules
4.3 Master/Remote selection
The Micro-Master Touch controller can support up to a total of 160 station outputs. This is dependant
on the number of remote units connected and the expansion modules fitted. One Micro-Master
Touch Master Unit can support up to four Touch Remote Units, each fitted with a variety of expansion
modules.
Configuration of a Touch Unit as either a Master Unit or Remote Unit is performed via a four switch
block, numbered 1 to 4, on the motherboard, next to the ribbon cable connector and above
Expansion Module number 1.
When configuring units, all power to the unit MUST be removed, including the backup
battery.
To designate a unit as the Master, all switches on the block should be in the OFF position.
For Remote Unit number 1, the number 1 switch should be ON, all others OFF.
For Remote Unit number 2, the number 2 switch should be ON, all others OFF.
For Remote Unit number 3, the number 3 switch should be ON, all others OFF.

Micro-Master Touch User Guide
10
© 2014 Toro Australia Pty Ltd Ver 1.2, June 2014
For Remote Unit number 4, the number 4 switch should be ON, all others OFF.
There can only be one Master controller and one of each of the remotes connected as a group.
In the example below, a unit has been configured as Remote Unit number 1.

4.4 Connecting Valve Wire
1. Remove bottom cover.
2. Route 1 wire from each valve though one of the three holes in the bottom of the
controller case. Insert each lead into the appropriate terminal on the connector.
For ease of wiring the connector heads can be removed if required.
3. The common wire for each valve should be attached to a single “Common” wire.
Connect this Common wire to one of the terminals labeled COMMON.
4. When all valve wires have been connected, ensure that all holes and spaces
between valve wires are sealed with a silicone sealant or similar. This ensures
that insects, ants and vermin cannot enter the controller.

Micro-Master Touch User Guide

© 2014 Toro Australia Pty Ltd Ver 1.2, June 2014
An example of correctly terminated valve wiring is shown below.
Figure 7 - Wiring Terminal Blocks
4.5 Earth Stake
The Micro-Master Touch controllers have a high level of field surge protection (4500 amp 20usec).
For this to work effectively, a good low resistance earth path must be provided to shunt the surges. A
resistance value <10 ohms is acceptable. A resistance value between 10-30 ohms is marginal. A
resistancevalue higher than 30 ohms is not acceptable. In severe lightning areas a 2 metre earth
stake connected to one of the GND terminals can be used ( Use multi-strand 4-6mm wire ).
Ensure soil around the earth stake is kept moist to create a good earth.
4.6 StandbyBattery
The Standby Battery is a 9V alkaline MN1604 miniature Battery. This will give several hours of
standby time. The alkaline battery is essential in high temperature conditions as they have a shelf
life of approximately 5 years at 40 degrees Celsius. In the long term, an alkaline battery will be more
reliable and cheaper than an equivalent NiCad battery. They are replaced every 1 to 2 years
depending on the number of power failures in the area.
Note: For extreme conditions with many power failures, a battery holder with (6 AA alkaline cells) will
give an increased Standby time.
NI-Cad (Nickel Cadmium ) batteries should not be used for 2 reasons.
1. For a Ni-cad to be efficient, the operating cycle should be fully charged, then fully discharged.
This is not the case for a Standby battery in an irrigation controller.
2. Poor operation in a high temperature environment. The capacity is only 20% of an alkaline cell
and this is further reduced in high temperature environment.
The 216 standard carbon zinc battery should not be used because of very poor high temperature
performance and low capacity.
4.7 12 Volt DC Operation
The Touch Series controllers can be easily changed to operate on 12VDC. It should only be used
with caution as valves must be fitted locally as wires carrying DC current should not be installed
under ground because of electrolysis. Ideal installation when hydraulic valves are used.
