2. Mounting the Equipment

Aqua Plus Control Center

The Aqua Plus is contained in a raintight enclosure that is suitable for outdoor mounting. The control must be mounted

a minimum of 5 ft. (2 meters) horizontal distance from the pool/spa (or more, if local codes require). The Control

Center is designed to mount vertically on a flat surface with the knockouts facing downward. Because the enclosure

also acts as a heat sink (disperses heat from inside the box), it is important not to block the four sides of the control. Do

not mount the Aqua Plus inside a panel or tightly enclosed area.

When selecting a location, note that the standard cables supplied with the Turbo Cell, flow switch, temperature sen-

sors, and valve actuators (if applicable) are all 15 ft. (5m) long.

Temperature Sensors

Three sensors are included with the Aqua Plus. A water sensor and an air sensor must be installed at all times for

proper operation. A solar sensor is required if the solar function is enabled.

Water Sensor

This sensor is used to measure the pool/spa temperature and is installed in the filtration plumbing after the filter but

before either the solar or conventionally fueled heaters—refer to the plumbing overview diagram.

1. Drill a 3/8” (10mm) diameter hole in the PVC piping and remove all chips and burrs.

2. Insert sensor until O-ring collar sits flush on the hole.

3. Position hose clamp over the sensor and gently tighten until O-ring makes an adequate seal. Do not overtighten.
4. For maximum temperature accuracy, cover the sensor and 3” (6cm) of pipe on either side with insulation and

white paint.

Air Sensor

Mount the air sensor outdoors.

IMPORTANT: Mount the air sensor out of direct sunlight.

Solar Sensor

For solar applications, mount the sensor near the solar collector array so that it is exposed to the same sunlight as the

collectors. Use additional cable (20 AWG) if necessary.

Chlorination Function

The Aqua Plus includes a Turbo Cell, cell unions and flow switch for use with the chlorinator function. Refer to pages

8 and 17 for plumbing and wiring instructions.

Optional AQL-CHEM ORP and pH Sensing Kit

The AQL-CHEM is an ORP and pH sensing kit for the Aqua Plus. When chlorination is enabled, the Aqua Plus senses

the pool's ORP and pH levels and generates the correct amount of chlorine to keep your pool properly sanitized.

Wiring and plumbing requirements for the AQL-CHEM should be considered before installing the Aqua Plus. Refer to

the AQL-CHEM manual for specific installation information.

Optional AQL-CHEM2 CO

Dispensing Kit

The AQL-CHEM2 is a CO

dispensing device that connects directly to the Aqua Plus. When used with an AQL-

CHEM, the Aqua Plus will sense the pool’s pH level and automatically dispense the correct amount of CO

to control

the pool’s pH to the desired level. Wiring and plumbing requirements for the AQL-CHEM2 should be considered

before installing the Aqua Plus. Refer to the AQL-CHEM2 manual for specific installation information.

If “VSP” is selected, the Lights relay is used to supply power to a Hayward Variable Speed Pump (VSP).
The relay will be on when the Lights output is on and off when the output is off . On, off and speed are
controlled by commands sent to the VSP.

Lights Interlock

If enabled, this feature will override the function (Manual On/Off, Countdown Timer, Timeclock) selected
above and turn the lights relay off when: filter pump is off, first 3 minutes of filter pump operation (allows
the pump to prime and get water flowing), when the pool/spa suction return valves are in any position
other than “pool only”, or for the first 3 minutes after solar turns on (allows air in the solar panels to be
purged). Interlock is not available for solar, low speed filter pump, super chlorinate or dimmer.

Lights External Input Interlock

When Lights External Input Interlock is enabled, the lights output will be forced off when the external input
is active. This will have precedence over freeze protection. Lights External Input Interlock is not available
for solar, low speed filter pump, dimmer, super chlorinate, or pH dispense functions.

Lights Freeze Protection

This function helps protect equipment that is wired to the lights relay against freeze damage. If Freeze
Protection is enabled and the AIR temperature sensor falls below the selected freeze temperature threshold,
the Aqua Plus will energize the lights relay. IMPORTANT: this only enables operation of the lights relay
during freeze--see the “Filter Pump Config.” menu to enable freeze protection for the main circulation
system.

Lights Pump Speed

This is the speed of the filter pump when the Lights output is on. The default selection is “Settings Menu”.
This is the speed of the pump that has been selected in the Settings Menu for normal filter operation. If an
alternate speed is desired when the Lights output is on, push “+” or “-” and select from “Filter Lowest” to
“Filter Highest” in 5% increments.

NOTE: The configuration parameters for the Aux2 output are the same as shown below for Aux1.
