2. Mounting the Equipment
Pro Logic Control Center
The Pro Logic 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 Pro Logic inside a panel or tightly
enclosed area.
When selecting a location, note that the standard cables supplied with the Turbo Cell, flow switch, tem-
perature sensors, and valve actuators (if applicable) are all 15 ft. (5m) long.
Temperature Sensors
Three sensors are included with the Pro Logic. 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.
Optional AQL-CL Chlorination Kit
The AQL-P4 requires the use of the AQL-CL or AQL-CL-25FT chlorination kit when using the chlorina-
tor function. This kit contains a Turbo Cell, cell unions and flow switch. Refer to pages 9 and 18 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 Pro Logic. When used with the AQL-CL, the Pro
Logic 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 Pro Logic. Refer to the AQL-CHEM manual for specific installation information.
Optional AQL-CHEM2 CO
2
Dispensing Kit
The AQL-CHEM2 is a CO2 dispensing device that connects directly to the Pro Logic. When used with
an AQL_CHEM, the Pro Logic will sense the pool’s pH level and automatically dispense the correct
amount of CO2 to control the pool’s pH to the desired level. Wiring and plumbing requirements for the
AQL-CHEM2 should be considered before installing the Pro Logic. Refer to the AQL-CHEM2 manual
for specific installation information.

When the filter pump is running and the heater is on: Pressing the “Filter” button once will
cause the heater to turn off, but the filter pump will continue to run for heater cooldown (filter
LED flashing and message on display). Pushing the filter button a second time will override
the heater cooldown operation and turn the filter pump off.
Heater Extend
If “Enabled”, the filter extend logic keeps the filter pump running beyond the normal turn-off
time until the pool (or spa) is heated up to the desired temperature setting (see Settings
Menu). Heater extend will NOT cause the filter pump to turn on, it will only delay the turn
off time when the heater is operating.
Allow Low Speed
This menu only appears if the filter is configured for 2-speed or variable speed operation.
During default operation, high speed mode is used whenever the heater is on. If Allow Low
Speed is enabled, low speed will be allowed even if the heater is on.

Solar
If the solar control logic is “Enabled”, several additional steps must be taken to ensure
proper operation of the solar system. If the solar is operated by a valve, then the Valve3
output must be setup for solar logic (page 28). If the solar is operated by a pump, then one
of the AUX relays must be set up for solar logic (page 27). Also, the “solar” temperature
sensor must be installed. This sensor is typically mounted near the collector array and is
used to sense whether sufficient solar heat is available.
If solar is “Enabled”, the valve or solar pump relay will turn on when the water temperature is
less than the desired temperature setting AND the solar sensor is hotter than the water. The
desired temperature is in the “Settings Menu”. If applicable, the homeowner will be prompted
to enter separate pool and spa desired temperature settings. Depending on the position of
the pool/spa suction valve, the proper temperature setting will be used.
Solar Extend
If “Enabled”, the filter extend logic keeps the filter pump running beyond the normal turn-off
time if solar heat is still available. When solar heat is no longer available, both the solar
valve/pump and filter pump will turn off simultaneously. Solar extend will NOT cause the
filter pump to turn on, it will only delay the turn off time when solar is operating.
