Pump Start Relay Operation per Zone
Summary
When a system requires the use of a booster pump or pulls water directly from a creek or
pond, it’s imperative to include a relay to activate the pump each and every time. A pump
start relay is a relay box that activates a pump every time a zone is activated from the
controller. Zone valves are the individual valves that operate a group of sprinklers or drip
emitters. Hydrawise controllers support 6- to 54-zone valves, depending on the model.
Typically, one zone valve is turned on at a time and controls the irrigation in a specific area
of your landscape. Whenever one of the irrigation zone valves is told to open by the
controller, the controller also signals the pump start relay to turn the pump on.

Wiring (24 VAC)
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
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 “COM” (Common) terminal. Attach the opposite control wire to the M/V terminal.

NOTE: With an HC Hydrawise controller, any one of your 6 or 12 zones can be configured
to act as the pump start relay. We usually recommend wiring to the last zone that is not
being used in the controller.
Wiring to Power Source
Connecting the pump start relay should only be done by a licensed electrician following
local codes. Improper installation could result in shock or fire hazard.
1. To prevent electric shock, turn the main circuit-breaker switch to “off” prior to making
electrical connections.
2. Assemble conduit piping and connect AC power from the power source to one side
(LINE IN) of the relay.
3. Assemble conduit piping and connect wiring from the pump motor to the other side of
the relay (LOAD OUT).
4. Check to make sure there are no exposed or loose connections.

Online Setup
This setup option is prompted when you first go through the initial setup wizard in the
software.
The online instructions will refer to a MASTER VALVE but this same setting applies when
using a PUMP START RELAY (PSR).
NOTE: With an HC Hydrawise controller, any one of your 6 or 12 zones can be configured
to act as the pump start relay. We usually recommend wiring to the last zone that is not
being used in the controller.
Does your irrigation system have a master valve?
If you need to change this in the software after the setup wizard, refer to the instructions
below.
1. Log in to your Hydrawise account
2. Click on ZONES AND SCHEDULES for the PC or ZONES if using the mobile app.
3. Choose YES from the drop-down menu above the zones. If you have an HC controller,
choose the zone number to which you have the master valve wired.

Pump Start Relay Operation per Station
When selecting a PUMP START RELAY to be on/off for an individual zone, you can edit
the zone in ZONES AND SCHEDULES under ADVANCED SETTINGS. This option is
useful when one zone is using city water and another is using water from a different
source.
NOTE: This option is for HPC and HCC controllers only.
Follow the steps below to change this setting:
1. From the ZONES AND SCHEDULES page, click on the icon on the zone you would
like to edit.
2. Click on ADVANCED, which is located on the top blue search section.
3. Select USE GLOBAL MASTER VALVE SETTING to keep this circuit on or select
DISABLE MASTER VALVE to turn it off.

One Master Valve - Two
Controllers
There are many times when two controllers are being supplied from a single POC (point of
connection) or source of water. Hydrawise-ready controllers can be connected to a single
master valve using a isolation relay (part number REL2). This device will allow for two
controllers to share the same master valve with out any issues.
The few limitations include:
Only one controller can operate at a time.
A delay of at least five minutes between the operation of controller #1 and controller #2
is desirable.
Electrical alerts will apply for each controller.
Steps for set up.
1. Wire the relay according to the drawing below.
2. Set up the master valve in the the app for both controllers using the normal instructions
in the article here [1].
3. Set up a new master valve using the app for controller #2 as per normal instructions.
REL 2 is NEVER connected to high voltage. It is for 24 VAC devices only.

Master Valve (P/MV) Operation per zone
Brief Summary
A master valve is a normally closed valve installed at the supply point of the main line that
opens only when the automatic system is activated. Zone valves are the individual valves
that operate a group of sprinklers or drip emitters. Hydrawise controllers support 6 - 54
zone valves, depending on the model. 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 purpose of the master valve is to shut off the water to the irrigation system when none
of the zone valves are operating.
