AUTO BACKUP

• During a power outage without a 9V battery fitted, schedules will still be saved in the permanent memory chip
• Clock time (at the time of the power outage) will be retained in memory

9V BATTERY

• We recommend fitting a 9V alkaline battery to maintain clock accuracy during power outage
• This battery should be replaced annually
• When connected to 24V power pack, the unit will read FAULTY BATTERY if the 9V battery is low or not connected

POWER SUPPLY

• This unit runs off a 240V 50Hz single phase outlet, drawing 30W at 240V AC
• Internal transformer: Reduces 240V AC to extra low voltage supply of 24V AC
• Fully compliant with AS/NZS 61558-2-6
• 1.25 amp low energy, high efficiency toroidal transformer for long life performance
• Input: 24V AC 50/60Hz
• Output: Max 1 amp
• To stations: 24V AC 50/60Hz. 0.5 amp max (up to 2 valves per station)
• To master/pump: 24V AC 0.25, amp max
• Transformer and fuse capacity must be compatible with output requirements
• Overload protection: Standard 20mm 1 amp fuse with faulty station skip function
• Output circuits should be installed and protected in accordance with wiring rules

Installation and Wiring

MOUNTING THE UNIT

• Position the unit in a place that is convenient for valve wiring and near a power source
• Install near a 240V AC outlet
• We recommend mounting the unit at eye level
• Drive a #8 screw into the wall, leaving approx. 4mm exposed. Use a toggle bolt or masonry plug if necessary
• Hang the unit from the key at the back, ensuring it is properly seated
• Optional: Remove the terminal cover to add additional screws through the holes in the lower corners for extra stability

FIELD WIRING

• Hint: Strip approx. 6mm of insulation and place this under the loosened screw, tighten gently and check the cable is firmly held
• A maximum of 2 solenoid valves can be run off each output
• Connect one cable from the terminals to each solenoid valve
• Complete the circuit by looping a common cable to all valves and connecting to the COMMON (C) terminal

ELECTRICAL CONNECTION

• Installation must be carried out in accordance with these instructions and all Local, State and Federal codes
• Disconnect all 240V AC power before commencing any field wiring or solenoid valve connection

Introduction

• This 8 station (valve) unit is designed for residential applications
• Stations will water in sequential order 1 through 8 on the start days and times nominated

Key Features

• Up to 8 stations can be operated
• 7 day watering calendar
• Stations can be allocated to 3 different start times
• Each start can have a different watering day scheduled
• Maximum watering time is 255min (4hr 15min)
• WATER SAVER % feature to reduce all scheduled durations by a fixed percentage
• Master valve and pump start outputs
• Permanent memory: never lose your watering settings
• System test mode for easy checking of solenoid valves

Rain Sensor Connection

• A rain sensor detects rainfall and tells the controller to suspend watering, resuming after the sensor dries out
• It achieves this by severing the connection between controller and the solenoid valves
• To install a rain sensor, wire it to the common, between the controller and valves as shown below:

Pump Connection

• Do not attempt to drive a pump starter directly from the controller
• Pump start is provided by connecting one side of the coil from a suitable relay to the MASTER VALVE/PUMP START (P) output of the controller and the other side to the controller common
• For systems supplied with water from a pump, unused stations must be connected back to the last used station to prevent running against a closed head if run times are incorrectly set
• If your water is being supplied directly from the main water supply, it is recommended to install an approved MASTER VALVE. This is connected to the COMMON (C) and PUMP/MASTER VALVE (P) terminals

Troubleshooting

Symptom Possible Cause Suggestion
No display
Flat battery or no mains power or
fuse blown
Install a charged battery. If the display still doesn’t work, then check the transformer or the main power supply.
If main power supply is working, check and replace the fuse if necessary.
Station not working Faulty solenoid coil or
Broken cable
Swap faulty station wire on controller terminal block with known working station wire. If the faulty valve still does not work on the known working connection then the solenoid coil is faulty. The panel may need to be repaired or the cable may be broken. Fuse blows Incorrect wiring or bad wiring joint Check wiring and joints for a short circuit.
No automatic start
Incorrect programming or blown fuse
If unit works manually check settings.
Check fuse and field wiring.
System watering at random
Too many start times entered
Check number of start times entered and when they are scheduled to water. Reset the unit if necessary
