Overview
The Hayward VS Omni is a web enabled pool automation control with a convenient touchscreen
interface. Because it's packaged with a high efficiency variable speed pool filter pump, the VS Omni
is ideal for both retrofit and new pool/spa installations. Automatically and remotely control pumps, a
heater, a valve actuator, pool and yard lighting, and more. The VS Omni offers the next generation of
technology to manage pool/spa equipment, allowing communication to web connected computers
and mobile devices. You can now conveniently monitor your pool/spa and change settings anytime,
and from anywhere.
Please read through this manual thoroughly before attempting to install, configure or operate this
unit. A Quick Start guide is also included to offer concise information to experienced installers.
Features
The standard Hayward VS Omni offers the following functionality:
• controls up to 2 variable speed pumps for pool/spa filtration and water features
• controls up to 2 Smart Relays to turn on/off single speed pumps, pool lights, yard lights, water
features, chemical dispensers and more
• controls up to two valve actuators allowing you to manage two bodies of water (both pool and
spa) or can be used for water features, cleaners, solar heating, etc. (currently requires Hub to be
powered by 230 VAC)
• controls one conventional heater (electric heatpump or gas) and optional solar heater (for single
body of water applications only)
• inputs for up to 3 temperature sensors or external input devices
• built-in wireless to connect to the home’s router/access point (ethernet port provided for optional
wired connection)
• optional flow switch used to protect pool equipment by detecting water flow
Optional accessories (page 3) can expand the functionality of the VS Omni. Determine your needs
and select the necessary accessories before you begin the installation.
Equipment
VS Omni Hub
All incoming/outgoing wiring will be connected to the Hub. The VS Omni Hub can be powered by
either 115 VAC or 230 VAC. Input power should be constant, not from a timer. If a timer must be
used, set the timer to power the Hub continuously. For convenience, a 6ft Wiring Whip is included
with the VS Omni. This whip is intended to connect the Hub's input power to the variable speed
pump if using 230 VAC. This connection should be made inside of the Hub and will ensure that both
the Hub and pump are powered continuously.
The remaining connections, including the Control Pad, are all low voltage. Depending on your installation, these connections could be to a heater, Smart Relays, temperature sensors, actuator and a
flow switch.

USE ONLY HAYWARD GENUINE REPLACEMENT PARTS
Control Pad
The Control Pad is weather resistant and comes with a 15 ft cord. Its resistive touch screen with
flip down cover is designed to function year round directly in the elements. Because it plugs into the
Hub, it should be mounted close by, but in a location that is convenient for the user to periodically
view and change pool/spa settings.
The Control Pad features a USB connector for firmware updates and an Ethernet connector for an
optional direct connection to your router (if wifi won't be used).
Smart Relay
Smart Relays have 15 ft cable that wire to the Hub. They're used to control high voltage 115 or 230
VAC pool equipment like lights, water features, pumps and more. Power to the intended load must
be supplied separately and run through the Smart Relay. Smart Relays are rated for up to 20 amps
at 230 volts.
Temperature Sensors
Depending on your installation, up to 3 temperature sensors may be used. The VS Omni requires
a water temperature sensor for heater operation. If freeze protection is desired, an air temperature
sensor is also required. For solar heating systems, a solar sensor is necessary. Even if your installation doesn't require the use of temperature sensors, installing water and air sensors provides a
convenience to the user, especially during remote use.
Flow Switch (not included)
An optional flow switch can be used to detect leaks or clogs in the pool/spa plumbing.

Mounting the Equipment
VS Omni Hub
The Hub is contained in a raintight enclosure
that is suitable for outdoor mounting. It must
be mounted a minimum of 6 ft (2 meters) horizontal distance from the pool/spa (or more, if
local codes require). The Hub is designed to
mount vertically with the knockouts facing
downward. Do not mount the Hub inside a
panel or tightly enclosed area.
When selecting a location, note that the standard cables supplied with the optional flow
switch, temperature sensors, and actuators
are all 15 ft (5m) long. Additional low voltage connections will have to be made to the
pump and/or heater. 115 VAC or 230 VAC input power must also be run to the Hub. Try to
mount the Hub in a location where incoming/
outgoing wiring will be easily accessible.
Mount the Hub on a wall or flat surface. Select
mounting hardware that is appropriate for the
mounting surface and material. The Hub has two keyhole type mounting tabs on the top and bottom
of the enclosure requiring a total of 4 fasteners.
Control Pad
The Control Pad comes with a 15 ft cord and plugs into the Hub. It should be mounted in a location
that is convenient for the user to view and change pool/spa settings. When considering the mounting location, make sure there is enough clearance above the enclosure so that the flip door will be
able to be opened fully. Also be sure to allow enough clearance below the Control Pad to access
the USB and Ethernet connectors. For best viewing results, position the Control Pad where it won't
be subjected to direct sunlight.
The Control Pad has two keyhole cutouts on the back of its enclosure. To mount, screw the two
provided fasteners into the mounting surface at the desired location using the template found on
page 54 . Tighten until the bottom of the screw heads are 1/8" off the mounting surface. Position
the Control Pad cutouts over the screw and slide the unit downward. You may have to tighten or
loosen the screws slightly to fully engage the screw heads to get a snug fit.

USE ONLY HAYWARD GENUINE REPLACEMENT PARTS
Smart Relay
The Smart Relay is packaged with a single gang electrical box but can also be used with any existing
comparable standard electrical box with a minimum volume of 16.2 in3. If using 115 VAC, make
sure that there is a Neutral line inside the box before installation. If not, you must run a separate
Neutral wire to power the Smart Relay. This is not a concern if using 230 VAC. Note that conduit and
connections to the included plastic box must be non-metallic.
Find a location within 15 ft of the Hub with convenient access to the pool equipment that you intend
to control with the Smart Relay. Three threaded 1/2" NPT knockouts are provided for high voltage
power coming into the relay and for power out to the pool equipment. A Wiring Whip is included to
aid installation.
The Smart Relay has a manual On/Off button that can be used if communication is lost with the Hub.
Although this button is not functional during normal operation, mount the Smart Relay in an accessible location to use this feature in case of communication loss.
Mount the Smart Relay to a wall or other flat surface using the mounting holes which are designed
to accommodate #8 screws.

Temperature Sensors
Water Sensor
This sensor is used to measure the pool/spa temperature and is installed in the filtration plumbing
after the filter but before either the solar or conventionally fueled heaters.
1. Drill a 3/8” (10mm) diameter hole in the PVC piping and remove all chips and burrs.
2. Insert sensor until O-ring collar sits flush on the hole.
3. Position hose clamp over the sensor and gently tighten until O-ring makes an adequate seal.
Do not overtighten.
Air Sensor
Mount the air sensor outdoors. IMPORTANT: The air sensor must not be mounted in direct sunlight.
Solar Sensor
For solar applications, mount the sensor near the solar collector array so that it is exposed to the
same sunlight as the collectors. Use additional cable (20 AWG) if necessary.
Optional Valve Actuators
Currently, using an Hayward GVA-24 actuator or equivalent requires that the Hub be powered with
230 VAC. If powering the VS Omni Hub with 115 VAC, an actuator can't be used. For installation,
refer to the mounting instructions included with the unit. After configuring and first operating the
valve, note that the internal cams in the actuator may have to be adjusted depending on the way the
actuator is mounted on the valve and the desired valve action.
Plumbing
Optional Flow Switch
Only applicable if leak/clog detection is desired. The flow switch should be plumbed on the return
side at the very end of the pool pad plumbing. This will ensure that if a leak occurs anywhere at the
pool pad, the VS Omni will be able to detect it. Understand that if a leak occurs after the flow switch
(downstream), the VS Omni will not sense a no flow condition.
IMPORTANT: There must be at least a 12” (30cm) straight pipe run before (upstream) the flow switch.
IMPORTANT: To ensure proper operation, verify that the arrow on the flow switch points in the direction of water flow.
Variable Speed Pump
Refer to the included VS Omni Pump manual for plumbing information.

If replacing a 115 VAC pump, you can disconnect power at the pump and use it to power the Hub
only. The new variable speed pump however, requires 230 VAC which will have to be run separately.
Refer to the included pump manual for input power wiring.
If using an existing timeclock to power the Omni VS Hub, set it to run constantly. If the VS Omni Hub
will be connected to a panel or switch, the power will have to be left on continuously.
Grounding
Connect a ground wire from the primary electrical panel to the Hub's ground connection as shown in
the previous diagrams. Also ground each piece of high voltage equipment that is connected through
the Hub or Smart Relay.
Variable Speed Pump Input Power
The VS Omni pump requires a constant 230 VAC, 60Hz input power whether from the VS Omni Hub
using the Wiring Whip or directly from a service panel/switch. Refer to the VS Omni Pump manual for
the location of the wiring terminals as well as other related high voltage wiring information.

Smart Relay Load Wiring
A Smart Relay can be used to control either 115 or 230 VAC pool equipment. The relay is double pole
(makes/breaks both “legs” of 230V circuits or one "leg" of 115V circuits). Refer to the diagram below
for wire connections. Use the included Wiring Whip if the supplied electrical box will be mounted
within 6 ft of the power source. Red, black and green conductors are included for 230 VAC and a
white conductor is supplied if using 115 VAC input power. Use the included wire nuts for wiring connections. Use proper threaded strain relief fittings for conduit attached to knockouts. After wiring is
complete, carefully insert the cover with connections into the box and secure.
Low Voltage Wiring
Note: There is a low voltage channel on the right side of the Hub's enclosure labeled on page 10
and shown on page 21. All low voltage wiring that exits the Hub must run through this channel. The
included foam gasket (page 21) should be used to seal the channels's exit after wiring is complete.
Do not run low voltage wiring through a knockout or with any high voltage wiring.

Smart Relays
Like VSPs, Smart Relays rely on communication from the Hub. Their 4 conductor cable is wired to
the same connector as a VSP. Wire the cable as shown below. Up to two Smart Relays can be controlled by the VS Omni. In addition to communication wiring, the Smart Relay will be wired to high
voltage pool equipment shown on page 13.
Valve Actuators
When wired for 230 VAC, the VS Omni can control up to two valve actuators which allow automated
control of pool/spa, water features, cleaners or solar heating. The VS Omni is compatible with standard valve actuators manufactured by Hayward, Pentair/Compool, and Jandy. Actuators have 15 ft
cables that are terminated with connectors that plug directly into the Hub as shown on page 10.
Temperature Sensors
The Hub utilizes 10K ohm thermistor type sensors with 15 ft cable. If a longer cable is required, contact the Hayward service dept. (908-355-7995) for information on suitable cable types and splices.
Temperature sensors are wired to the 8 position connector shown on page 10 and on the following page. To unlock, push on the corresponding lever with a small tool as shown. When pushed,
the connector will be open and able to receive the wire lead. For best results, strip back leads 1/8"
before inserting. After the wire is fully inserted, release the lever and the wire will lock in place.
