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 Con-
nector 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.
