Hayward Pro Logic® Installation Manual page 17

Two speed filter pump: Requires 2 relays (FILTER plus one of the AUX relays) for proper operation of both
speeds. ! IMPORTANT: Be sure to follow the wiring diagram below AND to configure the control
logic according to the instructions on page 26.
Lights: A ground fault circuit breaker 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 the "Lights" relay and then connect the color wheel to one of the AUX outputs.
ColorLogic networked pool/spa lights require the installation of an AQL-COLOR-MODHV and unique wiring.
Refer to the AQL-COLOR-MODHV manual for detailed installation and wiring 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 Pro Logic can
control up to 2 Hayward TriStar VSPs and 8 EcoStar VSPs. Refer to the diagram below for proper input wiring
to the VSP. Wiring from the 220V breaker must connect through the Pro Logic's Filter/Lights/Aux relay. Refer to
VSP Address Setting on page 18 to determine which relays can be used with your pump. The selected relay will
supply input power to the VSP pump control and be on when the output is on. When the output is off, the relay will
be off. Note that when the relay is off (power off to the VSP), the Pro Logic will not display errors or diagnostics
for the pump. The relay must be on for diagnostic function. Refer to the VSP manual(s) for detailed wiring
information.
pH Dispense Output: NOTE: The Pro Logic can only be used with a 120VAC pH dispensing device. There
are two Pro Logic versions that require different installation techniques. Pro Logics operating with a software
version less than 4.00 require the pigtail or pH dispensing device to be connected to an internal relay. Units using
version 4.00 or later have a dedicated pH output through the screw terminals mounted on the inside of the enclo-
sure (shown on page 12). Refer to the AQL-CHEM's pH dispense wiring instructions that relates to your particu-
lar version.
Hayward ColorLogic Network Module: Refer to the AQL-COLOR-MODHV manual for detailed installation
and wiring information.
