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. De-
pending 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 Wir-
ing 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 instal-
lation 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 fol-
lowing 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.
