You can upload multiple images per zone. The total number of images that can be uploaded is based on the
images size and is different for each account’s Plan Subscription.
After an image is uploaded you can select an image to be displayed on the Dashboard by editing the zone
and selecting the image in the Zone Icon list.
Configuring a Master Valve
A master valve is an automatic valve that is installed at the point where the irrigation system connects to
the water supply. (Sometimes this circuit is called a “pump start circuit.” Both types of circuits work similarly
and can be used for a pump and/or a master valve.) The controller turns the master valve on and off.
Zone valves are the individual valves that operate a group of sprinklers or drip emitters. Typically one zone
valve is turned on at a time, and controls the irrigation in a specific area of your garden. Whenever one of
the irrigation zone valves is told to open by the controller, the controller also signals the master valve to
open - the master valve acts like a back up valve, or a fail-safe valve. The purpose of the master valve is to
shut off the water to the irrigation system when none of the zone valves are operating.
The image below shows a master valve operating connected to Zone 12 on a Hunter HC controller.

Different Hydrawise-Ready controller models have different options when selecting a master valve. With a
Hunter HC controller, any one of your ordinary zones can be configured to act as a master valve, with all
other Hydrawise-Ready controller models there is a dedicated master valve.
The master zone is configured on the Zones & Schedules page underneath your list of irrigation zones as
highlighted in the image below.
