Equipment
Wiring Hub
All incoming/outgoing wiring will be connected to the Wiring Hub. The OmniHub can be powered
by either 230 VAC or 115 VAC. Input power should be constant, not from a timer. If a timer must be
used, set the timer to power the Wiring Hub continuously. For convenience, 6 ft Wiring Whips with
red, white, black and green colored 12AWG wires are included with the OmniHub.
The remaining connections to the Wiring Hub, including the Control Pad, are all low voltage. Depending on your installation, these connections could be to a variable speed pump, Smart Relays,
temperature sensors, actuator and a flow switch.
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 Wiring 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. Lastly, the Control Pad contains the Wifi radio and its location
should be considered if planning to use a wireless connection to the home router or access point. A
wireless mobile device (phone, tablet, etc.) could be used to test the signal strength at the intended
mounting location. The Control Pad features a USB connector for firmware updates and an Ethernet
connector for an optional direct wire connection to your router (if wifi won't be used).
Smart Relay
Smart Relays have a 15 ft communication cable that connects to the Wiring Hub and are used to
control high voltage pool equipment like lights, water features, pumps and more. 115 VAC or 230
VAC 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 OmniHub 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. A flow switch
is required if using chemistry Sense and Dispense accessories.
Overview
Before attempting to install the OmniHub, familiarize yourself with the installation steps on the following pages. Also refer to the sample overview diagrams on page 6. Diagram 1 shows wiring
to a single speed pump and a conventional gas heater. Single speed (and two speed) pumps are
controlled by Smart Relays. In this example the high voltage for the conventional gas heater is wired
in parallel with the Wiring Hub. A Wiring Whip is used for this connection. A separate remote control
connection is made from the Wiring Hub to the heater.

Mounting the
Equipment
Wiring Hub
The Wiring 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 Wiring Hub is designed to mount vertically with the knockouts facing downward. Do not
mount the Wiring 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 heater and VSP, if used. 230 VAC or 115 VAC input power must also be run to
the Wiring Hub. Try to mount the Wiring Hub in a location where incoming/outgoing wiring will be
easily accessible.
Mount the Wiring Hub on a wall or flat surface. Select mounting hardware that is appropriate for the
mounting surface and material. The Wiring 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 Wiring 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 57. 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.

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 Wiring 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
Wiring 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. Refer to page 17 for Smart
Relay LED information.
Mount the Smart Relay to a wall or other flat surface using the mounting holes which are designed
to accommodate #8 screws.

USE ONLY HAYWARD GENUINE REPLACEMENT PARTS
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
For installation, refer to the mounting instructions included with the Hayward GVA-24 actuator or
equivalent. 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
Flow Switch
A Hayward GLX-FLO flow switch (sold separately) is required if an HL-CHEM ORP & pH Sensing Kit
will be used. If no chemistry equipment is installed, the GLX-FLO is optional and can be used to
detect leaks or clogs in your pool's plumbing system. If using the GLX-FLO, it must be plumbed in
line with any chemistry sensing/dispensing equipment at the very end of the return plumbing. This
will ensure that the OmniHub will detect a leak if it occurs anywhere at the pool pad. Understand that
if a leak occurs after the flow switch (downstream), the OmniHub 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.
Filter Pump
If the OmniHub has been packaged with a filter pump, refer to the included pump manual for plumbing information.

Electrical Wiring
The Wiring Hub requires both high and low voltage connections. Always:
- Ensure that Power is disconnected prior to performing any wiring
- Follow all local and NEC (CEC if applicable) codes
- Use copper conductors only
A dedicated channel on the right side of the Wiring Hub has been provided for all low voltage wiring.
All low voltage wires should run through this channel to exit the Wiring Hub. A weather resistant
gasket is provided (see page 23) to seal this exit.

High Voltage Wiring
Hub Input Power
The Hub requires a constant 115 VAC or 230 VAC input power to operate. A wiring harness is included and will plug into the input power connector shown on page 11. Wire the harness according
to the diagram below.
Wiring Filter Pump Input Power
Note that Hayward supported variable speed pumps (VSPs) will connect to the OmniHub differently
than single speed (or two-speed) filter pumps. Single and two speed pumps are wired to Smart
Relays while VSPs are wired to a constant power source. The following information will show how to
wire both types. Refer to your filter pump's manual for the location of the input wiring terminals as
well as other related high voltage wiring information.
Powering Hub and VSP with Same Voltage
Variable speed filter pumps require constant power and are turned on and off through low voltage
communication wiring from the OmniHub. Because the OmniHub must also be powered continuously, it may be most convenient to wire the VSP and OmniHub in parallel, on the same circuit. If this
is the case, they must both be powered by the same voltage. An example of this is shown below.
As shown in Diagram 2 on page 6 and below, power can come from an existing timer, switch or an
electrical panel. Because both units need to be powered constantly, if power comes from a switch
or timeclock, set it to run continuously.

Powering Hub and VSP with Different Voltage
Wire the Hub and VSP separately if using different voltages for both. If the new pump requires a different voltage than the old, run a separate source from the electrical panel. The Hub, which can be
powered by either 115 VAC or 230 VAC, can be powered by the existing timeclock or switch. Both
units need power constantly so if there is a switch or timeclock in the system, it must be set to run
continuously.
Powering Hub and Single Speed Pump with Same Voltage
Single speed pumps require the use of Smart Relay(s). High voltage connections are made directly
to Smart Relays which are turned on and off through a low voltage communication connection to the
OmniHub. Like the OmniHub, Smart Relays can be powered by either 115 VAC or 230 VAC.
Connect 115 VAC from the
panel, timeclock, outlet or
switch. Make sure OmniHub is powered constantly.

The example below shows a typical retrofit of the OmniHub into a system with an existing 115 VAC
filter pump. In this case, switched or timed input power to the pump is disconnected and distributed
to the input sides of both the OmniHub and a Smart Relay. Because the OmniHub and Smart Relays
require constant power, an existing timeclock or switch must be set to power both constantly. The
115 VAC pump is then wired to the output side of the Smart Relay.
Note that this connection method will work for 230 VAC, using the 230 VAC connections on the
Smart Relay.

Smart Relay Load Wiring
A Smart Relay can be used to control either 115 or 230 VAC pool equipment. Previous diagrams
showed a Smart Relay connected filter pumps but other high voltage equipment like accessory water
feature pumps, lights, cleaners, transformers, etc. can be controlled as well.
Smart Relays can be installed into an existing electrical box with a minimum volume of 16.2 in3 or
with the box supplied with the OmniHub. 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 wiring. 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 when attaching conduit
to knockouts. After wiring is complete, carefully insert the cover with connections into the box and
secure.
