INTRODUCTION

The Toro Lawn Dial Outdoor Irrigation Controller
is a programmable electronic timer that controls
the watering of six or eleven stations (depending
on the model) using remote solenoid valves.

In a typical irrigation system, there is a Master
Valve (MV) which is switched on whenever one of
the Station Valves (SV) is on.

The Controller is also suitable for use on water
supplies derived by pump from a bore or a dam.
In this case, the Master Valve control line is used
to turn on a Pump Start relay which controls the
power to the pump. The Pump Start relay is not
supplied with the controller. A Relay should be
installed by a qualified electrician.

Note that the Lawn Dial Controller will not power
the pump; it will only control an auxiliary relay

that switches power to the pump.

FEATURES

• Easy to install and program.

• 6 individual Programs.

• 6 individual Start Times per Program.

• 3 dierent watering cycles – day of the week,

odd/even days, and interval.

• Water Budget feature which provides easy

adjustment of watering for seasonal or
weather conditions.

• Rain Sensor function (external sensor

required) to prevent watering when it has
rained.

• Pump delay feature (for use with a bore or

dam pump).

• Station delay feature used to prevent or

reduce issues caused by slow closing
solenoid valves.

• Permanent memory for the retention of all

programmed information. In the event of a
loss of mains power, data will be saved for
up to 5 years. This occurs even if a backup 9V
battery is not fitted.

• Battery back-up (9V battery supplied).

• Weather resistant controller with 240VAC

power lead and plug.

INTRODUCTION TO PROGRAMMING WATERING SCHEDULES

When programming the controller, there are the
following to consider:

STATIONS OR ZONES

your controller has either six (6) or eleven (11)
Stations, depending on the model. Each Station
has a group of sprinklers in a specific portion
(Zone) of the garden and is controlled by a
solenoid Valve. Zones are generally laid out
according to the type of plant material being
watered and the type and flow rate of the

sprinklers used to distribute the water.

PROGRAMS

up to six (6) watering Programs can be set and
applied to any of the Stations. For each Program,
the following are programmable:

• Watering Days

watering may be programmed to occur on

- fixed days of the week
(eg. Mon, Wed and Fri),

- at intervals of a number of days
(eg. every third day), or

- on odd or even days of the month
(eg. 1st, 3rd, 5th, 7th etc.)

• Start Time

each program may have up to six (6)
Start Times

• Run Time
each Station (or Zone) has an associated

Run Time

Programming is a lot easier if you first fill out a

Watering Schedule Form, an example of which is

on the next page. You will have a record of your
watering schedule and zone locations which can
be kept with your controller. In the
example, four Programs have been
programmed:

• Program 1 starts at 7:00am on Mondays and

Thursdays and runs for 20 minutes on
Stations 1, 2, 3, 5 and 6

• Program 2 starts at 9:00pm every day and

runs for 10 minutes on Stations 3 and 6. Note
that if no Watering Days are programmed,
the Lawn Dial Controller defaults to every day

• Program 3 starts at 6:00am every third day

and runs for 10 minutes on Station 4 only

• Program 4 starts at 5:00am on Tuesdays and

Sundays and runs for 30 minutes on Station
6 only.

Note: The Controller runs all programmed

watering sequentially, with only one Valve open
at any given time. In the example, Program 1 will
water Station 1, then Station 2, then Station 3,
then Station 5 and then Station 6, beginning at
7:00am, and taking a total time of 100 minutes.

If another Program was scheduled to start at say
8:00am, it would be delayed until 8:40am (the
completion of Program 1).
Therefore, when scheduling multiple programs
and/or multiple start times within each
program, make sure that each program cycle
can run to completion before the next program
cycle is scheduled to start. If you do not do this,
the Controller will automatically stack them in
sequence.

FILLING OUT WATERING SCHEDULE FORM

VALVE NUMBER

In the area at the top of the form, fill in the area
and/or type of lawn or garden which is to be
watered by each Valve. In the example, three of
the valves are watering turf (lawn), two are
watering flowers and one is watering vegetables.

WATERING DAYS

For each Program (1 to 6), write in the days of
the week that watering is required (eg. Mon,
Wed, Fri), or the interval between waterings (eg.
3 days – water every third day), or Odd or Even
if restricted watering is imposed, based on your
house number.

RUN TIME (minutes)

For each of the Programs and each of the
Stations, write in the Run Time required. Run
time can be set to any time between 1 minute
and 12 hours and 59 minutes.

START TIME

Write in the Start Times for each of the six
Programs. Each program can have up to six
assigned start times.

SETTING UP WATERING PROGRAMS

Up to six Programs may be entered, each requiring the programming of:

• Watering days – applied to all Station numbers and Start Times

• Start times – up to six

• Station numbers - up to four or six, depending on the model

• Station Run Times – may be dierent for each Station

For example, Program 3 may be set to water on Mondays and Thursdays (Watering Days), at 7am and
7pm (Start Times), and water Station 1 for 20 minutes, Station 2 for 10 minutes, and Station 4 for 30
minutes (Run Times).

An example of the use of six start times is the watering of a new lawn in very hot weather. It might be
watered for 10 minutes at 6am, 10am, 1pm, 3pm and 5pm.

RAIN SENSOR

The Rain Sensor function requires the connection of an external rain sensor with “normally closed” con­tacts, such as the Toro Wired Rain Sensor (Product Code TRS). When sucient rain is sensed, the relay
contacts close, resulting in the suspension of the automatic watering programs.

To install and use the rain sensor:

1 Open the Controller box and remove the cover

to reveal the Backup Battery and Control Wiring
Terminals.

Note: If a rain Sensor is not connected, leave the factory link as supplied

2 Remove the factory fitted link between the

“C” and “R” terminals.

3 Connect the rain sensor to the “C” and “R” terminals,

bringing the 2 wire cable through a hole in the bottom
of the box. The connections are not polarity sensitive.

4 Replace the terminal cover.

5 Turn ON the Rain Sensor switch in the top right corner

of the control panel.

Note: If left in the OFF position, the controller ignores the condition of the

Rain Sensor

Each station can be individually set to override the rain
sensor. This is useful, for example, if you have an area of
your garden that is under cover and does not receive any
rainfall.

The default position for the rain sensor is “o”, and it must
be turned “on” for each Station:

1 Select SET AUXILIARIES on the Control Dial. A

Station number will be flashing and OFF will be dis-

played.

2 Press and OFF will flash.

3 Press to change to ON.

4 Press and the Station number will flash.

5 Use and to select another Station number and repeat steps 2 to 4 until rain sensing is turned

on for all required Stations.

Note: When OFF is selected for a station, the controller overrides the rain sensor for that particular station.

Programmed watering may be suspended for between 1 and 10 days, a useful feature if, for example,
rain is forecast in your area for the next two days. Instead of turning the timer o (with the risk of
forgetting to turn it back on), watering can be delayed for three days, after which, programmed
automatic watering will resume at the next start time.

WATERING BUDGET AND SEASONAL ADJUSTMENT

Changes in season and temperature generally require a change in watering run times to maintain a
healthy landscape and conserve water.

The season adjust feature enables you to change simultaneously, all programmed Run Times, in steps
of 10%, from 10% of the programmed times up to 200%. The programmed Water Budget is applied to all
Stations and all Programs.

A 50% setting, for example, would decrease a
20 minute Station run time to 10 minutes and a
200% setting would double it to 40 minutes.

1 Select AUTO RUN on the Control Dial. The time

of day will be displayed.

MASTER VALVE ON/OFF SELECTION

Most domestic irrigation systems operate from a town water system, or a bore or a dam
(see Introduction).

The irrigation controller has a Master Valve output which is used to control a Master Solenoid Valve
when operating with a town water supply. The use of a Master Valve is highly recommended, particularly
if the pipe connections to the Station Valves are done using PVC push on and clip connections which are
prone to bursting open when continuously subjected to mains water pressure.

When using water from a bore or a dam, the Master Valve control line is used to control a Pump Start
Relay. The pump must be turned on with each individual Station Valve.

The default setting for the Master Valve is OFF. It must be turned ON for each individual Station.

To program the Master/Pump Start valve:

1 Select SET AUXILIARIES on the Control Dial.

2 Press the button once and the PEr screen

will be displayed.

3 Press the button again and STATION No

will be flashing and PUMP will show as OFF.

4 Press and OFF will flash.

5 Press to change to ON. Pressing will

return to OFF.

6 Press and the Station No will flash.

7 Use the and buttons to select another

Station No and repeat steps 4 and 5.

8 Repeat steps 6 and 7 until all Master Valve

programming has been completed for all
Stations.

PUMP DELAY

The pump delay feature can be used to allow the recovery of a bore water supply by delaying the
opening of Station valves. This allows the pump to operate against a closed head for a programmed
period of time, pressurizing the main line. This can be useful where draw down can occur in a bore.

Dierent delays can be set for each Station and the value can be between 0 (OFF) and 99 seconds.

Warning

This irrigation system allows the operation of a pump against a closed head (no valves open). This
has the potential to cause damage to the pump, pipes and other components in the irrigation system,
resulting in explosion, and should be used only in consultation with a hydraulic engineer.

INSTALLATION INSTRUCTIONS

MOUNTING THE CONTROLLER WIRING THE SOLENOID VALVES

ELECTRICAL WIRING

As the Controller comes with a 1.0m fixed power
lead, select a location for the Controller within

0.9m of an outdoor electrical outlet.

For safe, reliable operation, select an installation
site which will provide the following conditions:

• Protection from irrigation spray, exposure to

wind, heavy rain, snow and direct sun during
the hottest part of the day. The controller is
intended for use outdoors and can be exposed
to light rain as it is weather resistant.

• Access to a grounded power source which is

not controlled by a light switch or utilized by a
high current load appliance, such as a
refrigerator or air conditioner.

• Access to the sprinkler control valve wiring and

optional accessory wiring.

Using two screws, fix the controller to a wall
using the keyhole slot on the top centre of the
back of the weatherproof box, and the hole at the
bottom under the terminal cover.

Warning

High voltage (240V) electrical work must be

carried out by a licensed electrician. Failure to

do so will void the Controller warranty.

If the Controller is located outside, do not use

a power extension lead to reach a power point

more distant than 0.9m.

When the irrigation system is used on a town
water supply, the only high voltage wiring
needed is the provision of an electrical outlet to
supply power to the Controller. Alternatively, the
controller can be hard-wired to a 240V circuit.
If the Controller is located outside, a suitable
external power outlet is required.

If the system is used on a bore or dam water
supply and a pump start relay is required, all
240V electrical work must be carried out by a
qualified electrician.

Terminal Block, Backup Battery and Fuse Compartment

Low voltage wiring to the solenoid valves does not
require a licensed electrician.

Disconnect the controller from the mains power supply
before connecting the valves or performing any
maintenance work on the Controller or valves.

Solenoid valves have two cables. One (either one can be
selected) of the cables is connected individually back to
terminal 1,2,3,4, eta depending on the assigned station
number for the valve.

The remaining cable on each solenoid is connected to a
shared “common” wire and connected to the terminal
marked “C” on the controller (see diagram below)

Solenoid valves come with two wire tails which must be
connected to the cable from the Controller. These
connections must be made with an appropriate water
proof connector, such as the 3MTM Scotchlok IDC Con­nector range. Connections are not polarity sensitive.

When connecting the solenoid cables to the terminal
block, remove about 6mm of insulation from the end of
each wire and tightly twist stranded wires before
inserting into the terminal. (Terminals can accept a
maximum of 2.5mm cable)

Cables to the solenoid valves and rain sensor exit the
Controller through a round hole in the base of the box
(next to the Mains Power Cord). You will need to cut
the hole using a sharp knife or a drill. Once wires have
been run through the hole and are connected to the
terminals, reseal the gaps between wires and hole in
controller with silicon to impede water ingress.

INSTALLATION INSTRUCTIONS

RAIN SENSOR PUMP START RELAY CONNECTION

The controller is factory fitted with a link be­tween terminals R and C. If a Rain Sensor is not
to be used, then leave this link in place.

If a Rain Sensor is to be used, then remove this
link and connect the rain Sensor to terminals
R and C. The Rain Sensor must have normally
closed contacts that open when sucient rain is
sensed.

NOTE

The solenoid valve outputs are 24VAC and

designed to operate a maximum of two

solenoid valves per station. Station current

draw not to exceed 0.5 amps. Maximum

combined current draw including the master

valve/pump start relay and station shall not

exceed 0.8 amps.

Exceeding the maximum current draw may

damage the controller and void the warranty.

CAUTION

The controller cannot be used to power a

pump motor directly. As shown in the drawing

below, the controller provides 24VAC

(maximum current 0.5A) to switch an auxiliary

relay which switches power to the pump.

CAUTION

To prevent pump damage due to “dead-head-

ing” (the pump is running, a station has inad-

vertently been given a run time but no valve

is connected to the output terminal), connect

a jumper wire from any unused station termi-

nals to a used station terminal, as shown by

the red arrow in the above diagram.

Note: In the instance shown in the diagram

APPENDIX A - GUIDELINES FOR WATERING

WARRANTY

When deciding how much to water a garden or lawn, there are several factors to be considered:

• Soil type – clay, sand, silt, or a mixture of them

• Slope of the ground – does the water run o

• Type of grass or plants – the water needs of plants vary greatly

• Exposure to sun and shade – how much sun and at what time of day

• The rate at which water is applied – determined by the water pressure and the type of
watering nozzle used

• Time of day that watering takes place – the best time to water is one to two hours before sunrise

It is therefore dicult to devise the perfect watering schedule and some trial and error will be required
before you settle on the best schedule.

Here are some general watering hints to help you get started:

• Water early in the morning, one to two hours before sunrise, when the water pressure is highest and
evaporation is lowest and the water can soak into the plant root zone. Watering during generally mid­day or in the evening may cause plant damage.

• Newly planted lawns, until established, should be watered frequently for short durations to keep the
soil and plants moist at all times

• Reduce watering duration and water more frequently if water run o is occurring.

• Water an established landscape enough to saturate the soil without causing runo.

• When starting a new watering program, gradually decrease watering over a period of time until you
begin to notice signs of plant stress caused by lack of water, then increase watering a little to regain
plant health and vitality. This method enables a healthy landscape to be maintained using the least
amount of water.
