Low Voltage Wiring - Hayward OmniLogic Installation Manual

Lights
A ground fault circuit breaker (GFCB) must be used to supply power for high voltage pool/spa lighting. Low voltage lights will require an external transformer.
For lighting systems that have both a light source and color wheel, connect the light source to one relay and then connect the color wheel to a different relay.
Hayward Variable Speed Pump
Proper installation of a Hayward Variable Speed Pump (VSP) includes high voltage input wiring, low voltage communication wiring, and menu configuration/
settings. The OmniLogic can control up to 2 Hayward TriStar VSPs and 8 EcoStar VSPs. Refer to the diagram below for proper 220VAC input wiring to the
VSP. Refer to "Low Voltage Wiring" section in this manual for information on communication wiring. Refer to the VSP manual(s) for detailed wiring information.
pH Dispense Output
When used with a Hayward HL-CHEM, a pH dispensing device may be used. The HL-CHEM is an ORP and pH sensing kit that is offered as an accessory for
OmniLogic pool automation controls. The HL-CHEM continuously tests the pool's sanitization and pH levels allowing the OmniLogic to automatically generate
the correct amount of chlorine and dispense the proper amount of pH reducer. Together, they provide an automated system controlling both sanitization and pH
balance. Refer to the HL-CHEM's owner's manual for detailed pH dispense wiring instructions.
Valve Actuators
The OmniLogic HLBASE can control up to four automatic valve actuators. When used with the optional Input/Output Expander Board (HLIOEXPAND), up to 8
valve actuators can be used. Two of the valve outputs are dedicated to the pool/spa suction (Valve2) and return (Valve1) valves. Valve3 and Valve4 is for general
purpose use (solar, water feature, in-floor cleaner, etc.). All of the valve outputs on the HLIOEXPAND are for general purpose use.
For installations with solar heating, Hayward offers the AQ-SOL-KIT-xx solar kit that contains a valve, actuator, and extra temperature sensor. The "xx" indicates
the valve type from the 2 choices below:
-1P 1.5" Positive Seal
-2P 2" Positive Seal
The OmniLogic is compatible with standard valve actuators manufactured by Hayward, Pentair/Compool, and Jandy. Actuators will connect to the VLV outputs
on the Main Board. Refer to the diagram on page 15 for the location of valve connectors (VLV) on the OmniLogic Main Board. Record all connections in the
Connection Table on page 15.
