Optional GLX-FLO Flow Switch
The 15 ft flow switch cable plugs into the flow switch connector shown on page 11. Ensure that the
connector catch “snaps” into place in order to provide a reliable connection.
Optional Sense and Dispense
The OmniHub can be used with the Hayward HL-CHEM Sense and Dispense Kit. Using the HL-
CHEM, the OmniHub will continuously monitor the pool's pH/ORP levels and automatically dispense
chemicals (using a Hayward Aqua Rite salt chlorinator or a liquid/tablet feeder) to correct pH or add
chlorine when needed. The HL-CHEM connects in the same manner as a Smart Relay. Refer to the
HL-CHEM manual for installation instructions.
Optional Aqua Rite Salt Chlorination
The OmniHub can control an Aqua Rite chlorinator and generate chlorine based on the pool's
ORP level (using HL-CHEM) or as a percentage of run time, producing small amounts periodically
throughout the day. The standard Aqua Rite requires an HLAQRPCB communication board (sold
separately) and connects to the OmniHub in the same manner as a Smart Relay. The HLAQR940
bundle (O AQR940 Aqua Rite) contains the HLAQRPCB kit which can be used with minor
