Installing and Wiring Your Controller

After you have unpacked your Hydrawise irrigation controller, there are two simple steps to get started:

  1. Hardware Installation
  2. Connecting Solenoid Valves

You can also find the instructions included with the controller on our Downloads page.

NOTE: Once you’ve wired and installed your controller, please see Configuring Your Controller for instructions on how to connect to your Wi-Fi.

Hardware Installation

Controller Location

The Hydrawise controller is designed for installation in a protected location.

IMPORTANT: The chosen location must have Wi-Fi coverage. Wi-Fi coverage can be easily checked using an iPhone or smartphone that has Wi-Fi connectivity, or on the Hydrawise unit itself (signal strength is shown when you select a wireless name).

Cable Entry

The controller has two cable entry options: from the rear of the case, or via a conduit from the bottom of the controller.

Entry from the rear of controller Using a sharp knife, remove the two cutouts on the rear of the controller as indicated on the diagram in label 1.
Entry via 3/4 inch conduit Using a sharp knife, cut around the semicircular line on the controller as indicated on the diagram in label 2. Cut around the matching line on the blue controller wiring cover.

Mounting the Controller

  1. Using a 3/16-inch diameter drill bit, drill a hole to a depth of 1 inch (25 mm).
  2. Insert plastic anchor so it is flush with the surface of the wall.
  3. Screw 1-inch screw into plastic anchor, leaving the head protruding about 1/8 inch.
  4. Slide the controller case over the screw head.
  5. Mark your second mounting point (see label 3 in the diagram). Then remove the controller, drill a hole, and insert a plastic anchor. Finally, slide the controller case over the first screw head and screw it into place.

Connecting Solenoid Valves

Depending on the model you purchased, your controller has either 6 or 12 zones. For convenience, there are three common wiring points, and any or all of them can be used.

Refer to the diagram below when connecting your solenoid valves to the controller.

Solenoid Valve Wiring

  1. Take one wire from each solenoid. Twist the wires together and connect to the COMMON (usually black) wire of your multicore irrigation cable. Hydrawise recommends that all connections be soldered and sealed against moisture for long-term reliability.
  2. Connect each of the other individual solenoid wires to a different wire in the multicore cable and seal. Record zones against wire color for later reference.
  3. Connect the common wire from the multicore cable (usually black) to any of the three terminals on the controller marked COMMON.
  4. Connect each of the other solenoid wires to one of the zone inputs.
  5. If a master valve (sometimes labelled as MV on other controllers) is installed, this can be connected to any spare zone, as any of the zones can be assigned as a master valve output. The configuration of the master valve in the Hydrawise app is required.
  6. Click the blue wiring cover into place to seal the controller and protect the wiring.

Connecting the Plug Pack

  1. Use the plug pack supplied and connect the wires to the red AC terminal blocks on the unit marked as 24V. The polarity of the wiring is not important.
  2. Turn the power on. The power indicator will light up (see label 4 on the previous diagram).

Connecting Sensors or Flow Meters (Optional)

Hydrawise supports most open/close contact sensor types, such as standard rain sensors and soil moisture sensors.

  1. Connect one sensor wire to COMMON on the controller.
  2. Connect the Normally Closed or Normally Open wire from the sensor to SENSOR1 or SENSOR2 on the controller, and configure in the Hydrawise app.

For full details, refer to the instructions provided with your sensor or flow meter. Instructions for configuring the controller for a sensor are available here.

Troubleshooting Zone Issues

  • Try running a zone from the controller’s touch screen. If it works from the controller and doesn’t work from the app, check that you have linked your controller’s serial number to your account (see the previous section for details) and check your controller’s wireless status.
  • If your old controller had a master valve (sometimes referred to as MV), you must configure a master valve in the app and wire it to a spare zone on the controller. Detailed instructions can be found on the Hydrawise website.
  • Check that your wiring is correct. If no zones start, check that your COMMON wire is correctly cabled.
