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 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 4 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 16 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.

power to VSP
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.

External Input Interlock
The External Input Interlock provides a means to force the filter pump or an Aux output off when certain conditions
exists. A normally open or normally closed on/off external device must be connected to the Pro Logic as shown below.
After properly configuring the Pro Logic (see Configuration), the filter pump and/or desired Aux will be forced off
when the device is active.
SPST External Switch
(either Normally Open or Normally Closed)
Hayward Aqua Rite Chlorinator
The Pro Logic can control one or more Hayward Aqua Rite chlorinators when additional sanitizing capacity is re-
quired. A 4 wire connection is used to communicate to the Aqua Rite and can be wired up to 500' apart. Any outdoor
rated 4 conductor cable can be used. Refer to the wiring diagrams below for proper wiring connection to the Aqua
Rite. NOTE: There must be only 1 "primary" unit. All other Aqua Rite units must be configured as "secondary".
