WARNING: Do not use the Pro Logic to control an automatic pool cover. Swimmers may
become entrapped underneath the cover.
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 22.
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.
Hayward Variable Speed Filter Pump: Proper installation of the Hayward TriStar Variable Speed Control (VSC)
includes high voltage input wiring, communication wiring, and menu configuration/settings. Refer to the following
diagram for proper input wiring to the VSC. Wiring from the 220V breaker must connect through the Pro Logic's Filter
relay. The Filter relay is used to supply input power to the VSC pump control. The relay will be on when the filter
pump output is on. When the filter pump output is off, the relay will be off. Note that when the filter pump relay is off
(power off to the VSC), the Pro Logic will not display errors or diagnostics for the pump. The filter pump relay must
be on for diagnostic function.
Goldline 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 enclosure
(shown on page 10). Refer to the AQL-CHEM's ph dispense wiring instructions that relates to your particular version.
