Temperature Sensors
Three sensors are included with the OmniLogic. 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.
Air Sensor
Mount the air sensor outdoors. IMPORTANT: The air sensor must not be mounted in 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 Chlorination Function
The OmniLogic model requires the use of a chlorinator cell and plumbing kit to provide pool chlorination. These items are not included with the OmniLogic and
can be purchased separately at your local Hayward dealer. Choose a chlorinator cell model based on the size of your pool; models are shown below. 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 9 and 19 for plumbing and
wiring instructions.
• TCELLS340 (for pools up to 40k gallons) • TCELLS318 (for pools up to 18k gallons)
• TCELLS325 (for pools up to 25k gallons) • TCELLS315 (for pools up to 15k gallons)
Optional HL-CHEM Sensing Kit
The HL-CHEM is an ORP and pH sensing kit for the OmniLogic. When chlorination is enabled (requires chlorinator cell, liquid chlorine feeder or tablet feeder),
the OmniLogic senses the pool’s ORP and pH levels and generates/dispenses the correct amount of chlorine to keep your pool properly sanitized. Wiring and
plumbing requirements for the HL-CHEM should be considered before installing the OmniLogic. Refer to the HL-CHEM manual for specific installation informa-
tion. NOTE: OmniLogic is not compatible with AQL-CHEM.
Optional AQL-CHEM2 CO2 Dispensing Kit
The AQL-CHEM2 is a CO2 dispensing device that connects directly to the OmniLogic. When used with an HL-CHEM, the OmniLogic 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 OmniLogic. Refer to the AQL-CHEM2 manual for specific installation information.
Optional Remote Terminals
Hayward offers an optional wired remote terminal (HLWALLMOUNT) for fixed surface mounting as well as a wireless remote terminal (HLWIRELESS) for portable
convenience. Both give you the ability to control your pool’s functions from a remote location, away from the pool pad. The OmniLogic can also be controlled
remotely by various internet enabled devices such as phones, tablets and PCs.
HLWALLMOUNT
The HLWALLMOUNT is a wired touchscreen remote terminal designed to be mounted up to 500’ away (depending on cable gauge) from the OmniLogic. The
HLWALLMOUNT must be mounted indoors or in a weather protected area (rain should never touch the unit). It can mount over a single gang electrical utility
box or can be mounted directly onto any wall surface. When selecting a mounting location, refer to the HLWALLMOUNT manual for more information. Up to two
HLWALLMOUNTs can be connected to the OmniLogic.
Networking and Web Enabled Devices
The OmniLogic offers ethernet connectivity to the web through the home’s network. Once connected, web enabled devices such as a PC, laptop, tablet or phone
can be used to control and monitor the OmniLogic. For web connectivity, an ethernet cable must be run from the OmniLogic to the router or access point or a
wireless connection can be made to the home’s router using an optional HLWLAN.
HLWLAN
If running ethernet cable from the home’s router/access point to the OmniLogic is impractical, an optional HLWLAN can be used. The HLWLAN is a 802.11b/g/n
transceiver kit that can make a wireless connection up to 250’ to the home’s router/access point preventing the need to run cable for web access. Refer to the
HLWLAN Owner’s Manual for wiring and configuration information.
