Hunter Hydrawise HC Owner's Manual page 5

Use a minimum distance of 15' (4.5 m) between the controller and the relay to dampen
electromagnetic noise. In addition to this recommendation, Hunter also recommends all
controllers be mounted 15' (4.5 m) away from pumps and high-voltage devices.
1. Detach the pump start relay cover plate by removing the four screws with a
Phillips screwdriver.
2. Run a single wire from the "common" terminal on the controller to one of the yellow
wires on the pump start relay.
3. Run a single wire from the "P/MV" terminal on the controller to the other yellow wire on
the pump start relay.
4. Use wire nuts to make the connections and verify they are secure.
5. Install pump start relay cover plate and four screws. Close and lock the cabinet door.
6. Route wire through the conduit or one of the openings on the bottom of the cabinet.
7. Strip ½" (13 mm) of insulation from the ends of all wires. Secure the valve common
wire to the "COM" (Common) terminal. Attach the opposite control wire to the M/V
terminal.
