Low Voltage Wiring - Hayward OmniLogic HLBASE Installation Manual

Table of Contents

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): Transformers powering multiple UCLs must be wired to the same relay if synchronization is desired. If UCL(s) will be run-

ning in OmniDirect mode (lights built after June 2018), the transformer(s) must be wired to one of the OmniLogic's internal relays, not an HLRELAYBANK relay.

Refer to your Universal ColorLogic manual for more information about OmniDirect mode.

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 16 VSPs without the use of a relay. 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 Omni-

Logic pool automation controls. The HL-CHEM continuously tests the pool's sani-

tization and pH levels allowing the OmniLogic to automatically generate/dispense

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.

Low Speed Bus Jumper

The large Low Speed Bus connector (see page 10) is used for communication to various equipment

like variable speed pumps, Spa Side remote controls, and more. The connector can accommodate

multiple connections but if more capacity is needed, a jumper can be made using Wago lever nuts or

standard electrical wire nuts as shown. Refer to your equipment's manual for actual wiring instruc-

tions.

Hayward Variable Speed Pump (VSP) Wiring

Hayward VSPs connect to the OmniLogic's Low Speed Bus. Refer to your EcoStar or Tristar manual

for proper low voltage communication wiring between the OmniLogic and the Hayward Variable

Speed Pump.

Valve Actuators

The OmniLogic HLBASE can control up to four automatic valve actuators. When used with the op-

tional Input/Output Expander Board (HLIOEXPAND), up to 8 valve actuators 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/Com-

pool, and Jandy. Actuators will connect to the VLV outputs on the Main Board. Refer to the diagram

on page 12 for the location of valve connectors (VLV) on the OmniLogic Main Board. Record all con-

nections in the Connection Table on page 12.
