Why does it matter that my reticulation controller battery has gone flat? The answer is that it really matters if you have a water bore. Call us on 9246 0111.
What does a retic timer need a battery for anyway? There is a lot of misunderstanding about what a retic controller’s 9 volt battery does. Retic controllers have batteries to preserve the memory of that has been programmed in the event of a mains power fail.
The battery is normally only 9 volts and does not have the power to operate solenoid valves or pump start relays. Solenoid valves and most other irrigation devices operate on 24 volts. Most retic controllers are 240 volt mains powered with a transformer that steps down to 24 volt to operate the individual irrigation devices. It may seem like a minor inconvenience if you have a flat 9 volt battery in your controller as at first glance one would think it is not a big issue if you lose mains power and the controller has to be reprogrammed.
BUT it can have nasty consequences if the controller operates a bore.
If mains power is lost to quite a few brands of reticulation controllers and there is no back up battery then when mains power is restored the controller resets all programming to factory default which is often 10 minutes per station per day. This may then turn the bore on to stations that don’t exist and the pump runs with nowhere for the water to go. This can damage the pump or pipe work of the bore.
This season we attended 3 bores that had been affected like this from Ocean Reef alone. All after a power fail. These bores, incidentally should have had the unused stations ‘looped out’ to safeguard against this. Remember it is wise to change your disposable 9 volt battery at least once a year. Some newer model controllers have rechargeable batteries. You can test both types by simply turning mains power off and checking whether the display to the retic controller is still working and whether customer program’s have been retained when mains power is turned back on.
Please call us for any advise at all on 9246 0111 or go to our website.

Some retic controllers, like the Holman model pictured, look like they may be hard wired but this one actually had a plug pack transformer plugged into a power point in the roof.

We had a call today from a customer in South Perth who reported her submersible bore was not working. She thought her Rain Master reticulation controller was OK because the screen still had a display.
We took out the 9 volt back up battery and the display disappeared. This simple home test showed there was either no mains power to the reticulation controller or its internal 24 volt transformer had failed. The reticulation controller needs a 24 volt output to switch the relay, that in turn starts the 240 volt single phase bore or 440 volt DOL starter in the case of a 3 phase pumps.
A bit of an investigation by our servicemen at the South Perth call out revealed that in this case the controller transformer HAD failed. We replaced the controller and there were smiles all round as the bore fired up and the sprinkler came on.
