Equipment Ps-16 Expansion Unit; Temperature Sensors; Optional Chlorination Function; Optional Aql-Chem Orp And Ph Sensing Kit - Hayward Pro Logic® Installation Manual

PS-16 Expansion Unit
For the PS-16, the relays for Aux1-6 are contained in the Pro Logic Control Center. The relays for Aux7-14 are
contained in the PS-16 Expansion Unit. Valve outputs 7-10, in the PS-16 Expansion Unit follow the outputs of
Aux7-10, respectively.

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. An additional supplied sensor can be used for either solar or dual equipment function. If both
solar and dual equipment functions are desired, an additional sensor will need to be purchased.
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 over-
tighten.
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.
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 (see page 9). Use additional cable (20 AWG) if necessary.
Dual Equipment Spa Sensor
For dual equipment applications (separate filter pumps and heaters for both the pool and the spa), mount the dual
equipment spa sensor after the spa filter but before the heater (see page 9). Use additional cable (20 AWG) if
necessary.

Optional Chlorination Function

The PL-PS-4/8/16 models require the use of a chlorinator cell and plumbing kit to provide pool chlorination.
These items are not included with the Pro Logic and can be purchased separately at your local Hayward dealer.
Choose a chlorinator cell model based on the size of your pool. The following models are available:
T-CELL-15 for pools up to 40,000 gallons
T-CELL-9 for pools up to 25,000 gallons
T-CELL-3 for pools up to 15,000 gallons
In addition to the chlorinator cell, a plumbing kit (P-KIT) must be purchased. This kit contains the cell unions and
flow switch. Refer to pages 11 and 21 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 chlorination function, 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-COLOR-MODHV ColorLogic Network Module
Using the optional AQL-COLOR-MODHV network module, the Pro Logic can fully control the color, speed,
motion and brightness of Hayward ColorLogic Generation 4 pool and spa lights as well as provide programmable
light shows. Refer to the AQL-COLOR-MODHV for detailed installation, wiring and operation information.
! IMPORTANT: Mount the air sensor out of direct sunlight.
