None of my zones/stations are watering:

There may be a programming error

• Check that your Irrigation Controller works manually
• If the unit works manually, check your programmed schedules for errors

The fuse in the Irrigation Controller may be blown

• Check the fuse in your Irrigation Controller as it may be blown and need replacing

Field wiring may be disconnected

• Ensure all field wiring is working and connected to the relevant solenoid valves

 A single station/zone isn't working 

The solenoid coil on desired station or zone may be faulty

• Check the solenoid coil on the station in question

(A good solenoid coil should read roughly 33Ω on a multimeter)

There may be a break in the field wiring

• Test both the field and common cables leading to the station in question for continuity
• Check for fault indications on the display or smartphone app for your Irrigation Controller
• Depending on your Irrigation Controller, there may be a fault indication displaying on the on-board display of your controller, or within any associated smartphone apps you are using (such as iGardener™ or Holman Home)

Extra Troubleshooting for Irrigation controllers

Screen displaying AC FAULT or no display visible

This indicates that there is no power to the unit and the screen is only being powered by the 9V battery.  To check this is the case, remove the 9V battery from the base of the controller, if the display disappears completely, there is no power to your unit. Your controller will not operate if there is an AC fault. Please check the power point or plug transformer pack for power. Using a multi meter is best for this action.

Replace the fuse.

If no power, there may be an issue with the controller. Plug pack transformers for the indoor models are available from Holman’s or your local electrical retailer. These require a 1amp 240 to 24V AC/AC transformer.

AC connections from Transformer (indoor models only)

When connecting the AC transformer to the controller block, it makes no difference which wire goes to which AC terminal. The Terminals are not positive or negative, so as long as you have a wire to each AC terminal, the controller will receive power.

Fuse keeps blowing

The 1amp glass fuse is installed in the controller to protect the board from being damaged as a result of something wrong in the field wiring (this is the wiring from the solenoid to the controller)

If your fuse has blown, check that your wiring on each station is in tact and not damaged in any way.

If your fuse is continuously blowing, remove all wires from your stations. Reconnect each station one at a time to help determine which station is causing the fault.

What type of fuse.

Our irrigation controllers use a 5mm x 20mm 1amp glass fuse. These are available at Auto and Electrical retailers

These can be ordered through your local Bunnings stores if they are not in stock, use the code HA5205M2

BUDGET is displaying on the screen.

This is showing that the water budget has been set. Water Budget is a percentage of the time you have set for your stations, this can be an increase or decrease in that time. To reset your water budget to the 100% default, please refer to your manual.

stations not running for the set time.

The water budget may be set to something other than 100%. Water Budget is a percentage of the time you have set for your stations, this can be an increase or decrease in that time. To reset your water budget to the 100% default, please refer to your manual.

Showing ODD/ EVEN days on display.

The controller will display this in the top right-hand corner of the screen even if your Watering Days are not programmed for ODD/EVEN day watering.

2 Stations running at the same time.

If 2 stations are running at the same time, this is likely to be a dirty solenoid. Dirt or debris caught in the diaphragm will not allow that station to shut off. To test if it is the solenoid, swap the station wires, if it still performs the same way, it is the valve and that will need to be flushed. Refer to this information ‘How to clean a dirty solenoid’ on our website.

Programme running thru multiple times/ controller not shutting off

Please make sure you only have one start time entered.

You do not need to set a start time for each valve.

When you turn the dial to set starts, if you only want it to come on once a day then you must only have one start time entered. E.g.: Program 1 Start 1 6.00am. You do not need to have a start for each station as they will come on automatically one after another for the time that you have set in station run times. Be sure Start 2,3 and 4 are then set to OFF
