Low Voltage Wiring - Hayward OmniLogic HLEXPAND Owner's 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.
Universal ColorLogic Lights (UCL): Multiple UCLs must be wired to the same relay if synchronization is desired. Refer to your ColorLogic manual for more
information.
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 HLEXPAND can control up to 16 EcoStar VSPs without the use of a relay. Refer to the diagram below for proper 240VAC 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.
Cl and pH Dispense Output
Refer to the HL-CHEM owner's manual for detailed high voltage wiring instructions for chlorine and pH dispensing.
Hayward Variable Speed Pump (VSP) Wiring
Hayward VSPs connect to the HLEXPAND in the same manner as the OmniLogic. Refer to your pump manual for proper low voltage communication wiring
between the HLEXPAND and the Hayward VSP.
Valve Actuators
The HLEXPAND can control up to four automatic valve actuators. When used with the optional Input/Output Expander Board (HLIOEXPAND), up to 8 valve actua-
tors can be used. Two of the valve outputs are normally used for the pool/spa suction (Valve2) and return (Valve1) valves. Valve3 and Valve4 are for general
purpose use (solar, water feature, in-floor cleaner, etc.). All valve outputs on the HLIOEXPAND can be used in any manner.
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 8 for the location of valve connectors (VLV) on the OmniLogic Main Board. Record all connections in the
Connection Table on page 8.
