Hayward Aqua Plus® Installation Manual page 15

! WARNING: Do not use the Aqua Plus 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 Aqua Plus 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 Aqua Plus'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 Aqua Plus 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 Aqua Plus can only be used with a 120VAC pH dispensing device. There are
two Aqua Plus versions that require different installation techniques. Aqua Pluss 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.
