  • Programs can be attached to a dosing recipe.

FAQ's

What does a tap timer do?

A tap timer is a simple way to automate your watering for your garden. They work by directly attaching to your tap and either manually or automatically setting a timer for the length of the watering cycle.

Whats the difference between a basic controller and a smart irrigation controller?

Basic irrigation controllers work on a push-button basis, you press the mode you want, and it does it for you. Smart irrigation controllers on the other hand adapt to your environment, particularly through rain sensors and temperature sensors. This reduces the amount of water used.

Can I install the controllers myself?

The controllers which we have tagged as residential can be done on a DIY basis. However, this requires a little bit of experience in handling connections.
