Mounting the Equipment
OmniLogic Enclosure
The OmniLogic is contained in a raintight enclosure that is suitable for outdoor mounting. The control must be mounted a minimum of 6 ft. (2 meters) horizontal
distance from the pool/spa (or more, if local codes require). The OmniLogic 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
OmniLogic inside a panel or tightly enclosed area.
When selecting a location, note that the standard cables supplied with the included flow switch and temperature sensors, as well as optional accessories like
Hayward TurboCells and actuators are all 15 ft. (5m) long. Try to mount the OmniLogic at a height where the touchscreen can be accessed easily.
The OmniLogic weighs close to 60lbs. and will require two people to position and install. Select the proper location and mounting hardware given the size and
weight of the unit. The OmniLogic mounting brackets require a total of 6 mounting bolts to fasten the OmniLogic to the mounting surface.
Note that there is a heat sink on the back of the enclosure. Refer to the following information regarding the OmniLogic heat sink:
In all cases the heat sink on the back of the OmniLogic panel should not contact the wall behind the panel. This restricts air flow and makes the heat sink less
efficient. A minimum separation of 1/8” (except for vinyl siding) should be maintained between any heat sink pin and the siding on the wall behind the enclosure.
In the case of a flat wall the mounting flanges on the enclosure ensure that the minimum clearance is maintained. For shingles, clapboards or other siding with
a non-flat profile, the installer must ensure the minimum separation. Refer to the diagram on below.
Special Installation Instructions for Vinyl Siding
IMPORTANT: The heat sink on the back of the OmniLogic panel cannot be allowed to contact vinyl siding; during normal chlorinator operation the heat sink pins
get warm enough to deform vinyl siding on contact. An increased minimum separation of 3/8” should be maintained between any heat sink pin and the vinyl
siding behind the enclosure.
Minimum Clearance between heat sink and mounting surface - 1/8”
For Vinyl Siding - 3/8”

USE ONLY HAYWARD GENUINE REPLACEMENT PARTS
5
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.

Some important notes regarding standard Pool/Spa systems:
1. The OmniLogic can be programmed to accommodate spa spillover, if desired.
2. A conventional heater (gas or heat pump) and solar can be used to heat both the pool and the spa.
3. If the chlorinator cell is plumbed prior to the pool/spa return valve, then both the pool and the spa can be chlorinated
4. The water sensor should be installed prior to any heater or solar and will display either the pool or the spa temperature, depending on the current operation
of the pool. The temperature will only be displayed when the filter pump is running.
5. If any water feature or pressure side cleaner boost pumps are used, be sure to enable the “interlock” feature (see CONFIGURATION for details) to ensure
that the pumps operate only when the filter pump is on and the system is in the “pool only” operating mode.
6. The plumbing diagram above is intended to be used as a general guideline and is not a complete plumbing schematic for the pool.
7. The air sensor must be installed if the freeze protection feature is enabled for the filter, valves, chlorinator, other pool functions.

Some important notes regarding the control of Dual Equipment Pool/Spa systems with shared heaters:
In the Pool/Spa Config., select:
1. When the system is configured for Dual Equipment:
a. The pool filter can be a one, two or variable speed pump.
b. The spa filter can be a one, two or variable speed pump.
c. The heater(s) will be dedicated to the spa whenever the spa filter is on and the spa temperature setting is not off.
2. The water sensor should be installed on the pool loop prior to the heater(s) and will display the pool temperature whenever the “Pool Filter” pump is running.
3. The dual equipment spa sensor should be installed on the spa loop prior to the heater(s) and will display the spa temperature whenever the “Spa Filter”
pump is running.
4. The OmniLogic can be programmed to accommodate spillover if desired. Note that spillover operation will be automatically suspended whenever the spa
filter pump is turned on.
5. The chlorinator cell and flow switch must be installed in the heater return path. If spillover is enabled, then the OmniLogic can chlorinate both the pool and
spa (during spillover operation). Otherwise, the OmniLogic will only chlorinate the pool when the spa does not control the heater(s) and the spa sanitization
will have to be handled manually.
6. If any water feature or pressure side cleaner boost pumps are used, be sure to enable the “interlock” feature (see CONFIGURATION for details) to ensure
that the pumps operate only when the “Pool Filter” pump is on and the system is in the “pool only” operating mode.

Optional TurboCell
The TurboCell (used for chlorine generation) must be plumbed AFTER the filter and heater. If installed on a pool/spa combination system, the cell must be
plumbed BEFORE the pool/spa return valve in order to allow proper chlorination of both the pool and the spa. Refer to plumbing diagram below:
The cell may be mounted vertically or horizontally, and water can move in either direction through the cell. Install using the 2” unions provided. Tighten unions
BY HAND for a watertight seal. For systems with 1½” plumbing use adapters (provided by installer).
Flow Switch (supplied with P-KIT)
A Hayward flow switch is required if using the optional TurboCell for chlorination, a liquid chlorine dispenser, chlorine tablet feeder or an AQL-CHEM2 for pH
dispensing. The flow switch is a safety device that ensures that water is flowing before the OmniLogic starts to generate/dispense chlorine or dispenses acid. It
must be plumbed in the same section of plumbing as the TurboCell or dispenser. Failure to properly install the flow switch can result in explosive gases or harsh
chemicals accumulating in the pool plumbing system.
IMPORTANT: There must be at least a 12” (30cm) straight pipe run before (upstream) the flow switch. If the switch is plumbed after the cell, the cell can be
counted as the 12” (30cm) of straight pipe.
IMPORTANT: To ensure proper operation, verify that the arrow on the flow switch points in the direction of water flow.

High Voltage Wiring
High Voltage Relays - (120/240V) Pool Equipment
All OmniLogic relays are double pole (they make/break both “legs” of 240V circuits) and are rated at 3HP/30A at 240V (1½HP/30A at 120V). Refer to the
diagram below for typical relay wiring. Record all connections using the table on page 12.
WARNING: Do not use the OmniLogic to control an automatic pool cover. Swimmers may become entrapped underneath the cover.
WARNING: Do not use the OmniLogic to control fire pits or fire features.
Two speed filter pump
Requires two relays for proper operation of both speeds. NOTE: When selecting relays for two speed operation, note that both relays must be within the Relay
Bank (HLRELAYBANK) or neither relay should be within the Relay Bank. The diagram below shows the pump connected to relays outside of the Relay Bank.

Lights
A ground fault circuit breaker (GFCB) 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 one relay and then connect the color wheel to a different relay.
Universal ColorLogic Lights (UCL): Transformers powering multiple UCLs must be wired to the same relay if synchronization is desired. If UCL(s) will be run-
ning in OmniDirect mode (lights built after June 2018), the transformer(s) must be wired to one of the OmniLogic’s internal relays, not an HLRELAYBANK relay.
Refer to your Universal ColorLogic manual for more information about OmniDirect mode.
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 OmniLogic can control up to 16 VSPs without the use of a relay. Refer to the
diagram below for proper 220VAC input wiring to the VSP. Refer to “Low Voltage
Wiring” section in this manual for information on communication wiring. Refer to
the VSP manual(s) for detailed wiring information.
pH Dispense Output
When used with a Hayward HL-CHEM, a pH dispensing device may be used. The
HL-CHEM is an ORP and pH sensing kit that is offered as an accessory for Omni-
Logic pool automation controls. The HL-CHEM continuously tests the pool’s sani-
tization and pH levels allowing the OmniLogic to automatically generate/dispense
the correct amount of chlorine and dispense the proper amount of pH reducer.
Together, they provide an automated system controlling both sanitization and pH
balance. Refer to the HL-CHEM’s owner’s manual for detailed pH dispense wiring
instructions.
Low Voltage Wiring
Low Speed Bus Jumper
The large Low Speed Bus connector (see page 10) is used for communication to various equipment
like variable speed pumps, Spa Side remote controls, and more. The connector can accommodate
multiple connections but if more capacity is needed, a jumper can be made using Wago lever nuts or
standard electrical wire nuts as shown. Refer to your equipment’s manual for actual wiring instruc-
tions.
Hayward Variable Speed Pump (VSP) Wiring
Hayward VSPs connect to the OmniLogic’s Low Speed Bus. Refer to your EcoStar or Tristar manual
for proper low voltage communication wiring between the OmniLogic and the Hayward Variable
Speed Pump.
Valve Actuators
The OmniLogic HLBASE can control up to four automatic valve actuators. When used with the op-
tional Input/Output Expander Board (HLIOEXPAND), up to 8 valve actuators can be used. Two of the
valve outputs are normally used for the pool/spa suction (Valve2) and return (Valve1) valves. Valve3
and Valve4 are for general purpose use (solar, water feature, in-floor cleaner, etc.). All valve outputs
on the HLIOEXPAND can be used in any manner.
For installations with solar heating, Hayward offers the AQ-SOL-KIT-xx solar kit that contains a valve,
actuator, and extra temperature sensor. The “xx” indicates the valve type from the 2 choices below:
-1P 1.5” Positive Seal
-2P 2” Positive Seal
The OmniLogic is compatible with standard valve actuators manufactured by Hayward, Pentair/Com-
pool, and Jandy. Actuators will connect to the VLV outputs on the Main Board. Refer to the diagram
on page 12 for the location of valve connectors (VLV) on the OmniLogic Main Board. Record all con-
nections in the Connection Table on page 12.

Heater Control
The HLBASE OmniLogic provides a set of 4 low voltage dry contacts that can be connected to most heaters with 24V control circuits. When used with the
optional Input/Output Expander Board (HLIOEXPAND), 8 dry contact relays are available. Refer to the following diagrams for wiring connections to generic and
Hayward conventional heaters. For Hayward Smart Heaters, refer to the wiring information on page 16. The manuals supplied with most heaters also include
specific wiring instructions for connecting the heater to an external control (usually identified as “2-wire” remote control). For millivolt or line voltage heaters,
contact Hayward Tech support, 908-355-7995. Refer to the diagram on page 12 for the location of heater connections (LVR) on the OmniLogic Main Board.
Record all connections in the Connection Table.
Generic Heaters
1. Wire heater to 120/240V power source per the instructions in the heater manual. The OmniLogic does NOT control the power going to the heater.
2. Wire the OmniLogic dry contact heater output per the diagram below. Many internal parts of the heater can get very hot--see the heater manufacturer’s
recommendations on the minimum temperature rating for wires. If no guidance is given, use 105°C rated wire.
3. Set any ON/OFF switch on the heater to ON.
4. Set the thermostat(s) on the heater to the maximum (hottest) setting.
Hayward Pre-2007 Heaters
Refer to the instructions in the heater manual for “2-wire Remote Thermostat” operation under “Remote Control Connections” and the diagram below:
1. Turn off power to heater.
2. Wire OmniLogic to terminals 1 & 2 (see diagram).
3. Leave jumper attached to terminals 4 & 5.
4. Move “BYPASS” dipswitch on heater circuit board to “ON” position (up).
5. Turn heater power back on.
6. Switch heater to either “Pool” or “Spa” (it doesn’t make any difference which is selected, the OmniLogic will take control).
7. Heater display should be “bO” (for “bypass On).
8. Heater will start whenever OmniLogic requests (when OmniLogic “Heater” LED is illuminated).

6. Be sure to put the heater’s control in either “POOL” or “SPA” mode.
7. The OmniLogic will now control the heater.
Smart Heaters
Smart Heaters are programmed with a Hayward Unique Address (HUA) which allows it to be fully controlled by a Hayward Omni pool automation control. Similar
to other Smart Devices such as select Hayward variable speed pumps, you will be able to remotely create schedules and setpoints for both heating and cooling
while displaying real time heater status and diagnostics for the Smart Heater. The Omni family of products provide a 3 wire cable connection used to commu-
nicate with the Smart Heater and requires firmware revision R4.3.0 or later.
Disconnect power to both the Smart Heater and the Omni control before removing their panels. Use a proper outdoor rated 3 conductor 22 AWG cable (20 AWG
for runs over 30 ft) for the connection from the Omni control to the Smart Heater. Route the cable through appropriate knockouts making sure they are not shared
with high voltage wiring. Refer to the diagram below showing a Hayward OmniLogic control wired to the Smart Heater. Note that the position of each colored
conductor is the same at both ends of the communication cable. Refer to your Smart Heater manual for specific wiring instructions. After the communication
cable is fastened and secure, refasten the panels.
