on the controller and configure in the Hydrawise app.
For full details, refer to the instructions provided with your sensor, or flow meter.
Once you've wired your sensor you must configure it in your Hydrawise account.

PRO-HC - Mounting Controller
INSTALLING THE PRO-HC CONTROLLER
Start by choosing a location with good Wi-Fi coverage. Wi-Fi coverage can be easily tested
using a smartphone. A high signal strength is recommended. Wi-Fi connectivity can also
be tested on the Pro-HC itself (signal strength is shown when you select a wireless
network).
MOUNTING THE CONTROLLER TO A WALL
All necessary hardware is included for most installations.
1. Use the hole at the top of the controller as a reference and secure a 1" (25 mm) screw
into the wall. Note: Install screw anchors when attaching the controller to drywall or
masonry wall.
2. Align controller with the screw and slide the keyhole on top of the controller over the
screw.
3. Secure controller in place by installing screws in the other mounting holes.

Note: The indoor Pro-HC is not water or weather resistant and must be installed indoors or
in a protected area. This device is not intended for use by young children. Never let
children play with this device.
Outdoor Cabinet:
The outdoor model is water and weather resistant. Connecting the outdoor Pro-HC to the
primary power should be done by a licensed electrician following all local codes.
1. Route AC power cable and conduit through the 1/2" (13 mm ) conduit opening on the
left side of the bottom of the cabinet.
2. Connect the wires to the transformer wire located inside the junction box. International
units are supplied with a built-in terminal strip. Always use a UL listed conduit 1/2" (13
mm ) male adapter when installing the AC wiring.
3. Insert the adapter into the 1/2" (13 mm ) hole at the bottom of the controller. Attach a
nut to the adapter inside the enclosure.
4. A battery is not required for this controller. Watering will not occur without AC power.
Since this controller has non-volatile memory, the program, clock and calendar will be
retained during a power outage.

Note: To be performed by a licensed electrician only. Always use UL listed ½" (13 mm)
conduit with male adapter when installing AC wiring. Pro-HC controllers are intended to be
supplied AC power with an over-current protected device. Improper installation could result
in shock or fire hazard. This device is not intended for use by young children. Never let
children play with this device.
PRO-HC - Connecting Solenoid
Valves
1. Route valve wires between control valve location and controller.
2. At the valve location, attach a common wire to either solenoid wire of all valves. The
most commonly used color for the common wire is white. Attach a separate control wire
to the remaining wire of each valve. All wire splice connections should be done using
waterproof connectors.
3. Route valve wires through the conduit and attach conduit to one of the openings on the
bottom of the cabinet.
4. Strip 1/2" (13 mm) of insulation from ends of all wires. Secure the valve common wire
to "COM" (Common) terminal. Attach all individual valve control wires to the appropriate
station terminals.
