Before you Begin
The HLEXPAND is an expansion panel accessory for the Hayward OmniLogic HLBASE pool control. The HLEXPAND increases the number of sensor/external
inputs, high voltage outputs (for pumps, water features, outdoor lights, etc.), low voltage outputs (for heaters, variable speed pumps, valve actuators, etc.) and
adds an additional chlorinator output to your existing OmniLogic, expanding the functionality of the HLBASE. A circuit breaker panel is included in the HLEX-
PAND for easy wiring to the additional equipment. For remote access through the internet, the HLEXPAND connects to the OmniLogic as well as the home’s
router using a standard Cat5/6 Ethernet cable which can be run up to 200 ft. away. If a hard wired connection to the router is difficult, a Hayward HLWLAN
wireless transceiver may be used instead.
Although the HLEXPAND looks similar to the OmniLogic, there is no touchscreen and all connected equipment is controlled through the OmniLogic’s touch-
screen, remote terminals, and web connected devices.

Installation Steps
DANGER of Death, Injury or Property Damage if procedure not followed. Dead front removal is required for this installation. Power to the HLEXPAND MUST
be shut off whenever the dead front is removed. This means a complete shutdown of power to the entire Expansion Panel.
This manual assumes that you have already installed the OmniLogic that will control this Expansion Panel. Follow the similar installation steps on the following
pages.
Mounting the Equipment
HLEXPAND Enclosure
The HLEXPAND 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 HLEXPAND 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
HLEXPAND inside a panel or tightly enclosed area.
When selecting a location, note that the standard cables supplied with the included temperature sensors, as well as optional accessories like a Hayward Turbo-
Cell and actuators are all 15 ft. (5m) long. Also, a 15 ft. Ethernet cable is included for connection to the OmniLogic so if mounting further away, you will need
to supply your own cable. An additional Ethernet connection must be made to the home’s router or a HLWLAN if remote web connected devices are to be used.
The HLEXPAND 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 mounting brackets require a total of 6 mounting bolts to fasten the enclosure to the mounting surface.
Note that there is a heat sink on the back of the enclosure. In all cases the heat sink on the back of the enclosure 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 adjacent diagram.
Special Installation Instructions for Vinyl Siding
IMPORTANT: The heat sink on the back of the HLEXPAND enclosure can-
not 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”

Temperature Sensors
Three sensors are included with the HLEXPAND. Depending on your application, these sensors may or may not be used. If more than 2 bodies of water will
be managed by the HLBASE you will need to use the Pool and/or Spa water temperature sensors on the HLEXPAND. The air temperature sensor is optional
and the solar sensor is required only if a second solar heating 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
The HLEXPAND’s air sensor is not used in any of the pool’s functions and is provided as a convenient way of monitoring an additional airspace. This sensor
can be mounted indoors or outside but not in direct sunlight. IMPORTANT: The Freeze Protection function will only reference the OmniLogic air sensor, not
the HLEXPAND’s air sensor.
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 HLBASE offers optional chlorination for the primary body/bodies of water. The HLEXPAND can provide chlorination for an additional body of water if
needed. This function requires a chlorinator cell and P-KIT (flow switch and cell unions) purchased separately at your Hayward dealer. Choose a chlorinator
cell model based on the size of your additional pool/spa. 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
Refer to pages 5 and 16 for plumbing and wiring instructions.
Optional HL-CHEM Sensing Kit
Like the OmniLogic, the HLEXPAND supports the HL-CHEM ORP and pH sensing kit for additional bodies of water. The HL-CHEM functions in the same
manner as described in the OmniLogic manual and can be used to control chlorine generation/dispensing and pH dispensing. Wiring and plumbing require-
ments for the HL-CHEM should be considered before installing the HLEXPAND. Refer to the HL-CHEM manual for specific installation information. NOTE:
OmniLogic and HLEXPAND are not compatible with AQL-CHEM.
Optional AQL-CHEM2 CO2Dispensing Kit
The AQL-CHEM2 is a CO2dispensing device that connects directly to the HLEXPAND. When used with an HL-CHEM, the HLEXPAND will sense the pH level
and automatically dispense the correct amount of CO2to control the water’s pH to the desired level. Wiring and plumbing requirements for the AQL-CHEM2
should be considered before installing the HLEXPAND. Refer to the AQL-CHEM2 manual for specific installation information.
Optional AQL-CHEM4-ACID, AQL-CHEM4-CHLOR Dispensing Systems
The OmniLogic and HLEXPAND can be used to control Hayward chemical dispensing systems. These units are large capacity, with 15 gallon pump and
tank and are capable of automatically dispensing acid for pH control (AQL-CHEM4-ACID) or liquid chlorine for sanitization (AQL-CHEM4-CHLOR).
Ethernet and Web Connected 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 this functionality, two Ethernet connections must be made to the HLEXPAND. First, a con-
nection from the HLEXPAND to the OmniLogic using the provided 15 ft. cable allows communication between the two units. Second, an Ethernet cable
must be run from the HLEXPAND to the home’s router/access point or to a Hayward HLWLAN.
HLWLAN
If running Ethernet cable from the home’s router/access point to the HLEXPAND is impractical, an optional HLWLAN can be used (see page 14). The
HLWLAN is a 802.11b/g/n transceiver kit that can make a wireless connection up to 250 ft. 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.

Optional Valve Actuators
Like the OmniLogic, optional actuators can be used with the HLEXPAND. Note that the internal cams in the actuator may also have to be adjusted depending on
the way the actuator is mounted on the valve and the desired valve action.
Plumbing
Optional TurboCell
The TurboCell 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 dis-
pensing. The flow switch is a safety device that ensures that water is flowing before the OmniLogic/HLEXPAND starts to generate/dispense chlorine or dispenses
acid. It must be plumbed in the same section of piping 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.

Main Service (Power to the Circuit Breaker Subpanel)
The HLEXPAND circuit breaker subpanel can accommodate up to 12 circuit breakers and is rated for 100A service. Run properly rated conductors (L1, L2, N,
and ground) from the primary house electrical panel to the main power connections on the HLEXPAND circuit breaker base. The connection at the main house
panel should be to a 240VAC circuit breaker rated at 100A maximum.
Grounding and Bonding
Connect a ground wire from the primary electrical panel to the HLEXPAND ground bus bar. Also ground each piece of high voltage (120 or 240VAC) equipment
that is connected to the HLEXPAND control relays or circuit breakers. The HLEXPAND should also be connected to the pool bonding system by an 8AWG (6AWG
for Canada) wire. A lug for bonding is provided on the outside/bottom of the enclosure.
Circuit Breaker Installation and Wiring
Circuit breakers are to be supplied by the installer. Refer to the circuit breaker chart below for a list of suitable circuit breakers that can be used. Follow the
code and the circuit breaker manufacturer’s rating requirements regarding the size and temperature rating for wiring. Note that some pool equipment may be
required to be connected to ground fault circuit breakers—check local and NEC (CEC) codes.
General Purpose Outlet
If desired, a duplex receptacle with weatherproof cover (supplied by installer) may be installed in the knockout on the lower right side of the HLEXPAND enclo-
sure. Per code, use a GFCI type receptacle or a standard receptacle protected by a Ground Fault Circuit Breaker.
HLEXPAND Power
The HLEXPAND requires 120VAC, 5A power to operate the control logic circuits and the chlorinator. This power should be connected to a dedicated circuit
breaker.
WARNING: 120VAC only (permanent damage will occur if connected to 240V)

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): Multiple UCLs must be wired to the same relay if synchronization is desired. Refer to your ColorLogic manual for more
information.
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 HLEXPAND can control up to 16 EcoStar VSPs without the use of a relay. Refer to the diagram below for proper 240VAC 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.
Cl and pH Dispense Output
Refer to the HL-CHEM owner’s manual for detailed high voltage wiring instructions for chlorine and pH dispensing.
Low Voltage Wiring
Hayward Variable Speed Pump (VSP) Wiring
Hayward VSPs connect to the HLEXPAND in the same manner as the OmniLogic. Refer to your pump manual for proper low voltage communication wiring
between the HLEXPAND and the Hayward VSP.
Valve Actuators
The HLEXPAND can control up to four automatic valve actuators. When used with the optional Input/Output Expander Board (HLIOEXPAND), up to 8 valve actua-
tors 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/Compool, and Jandy. Actuators will connect to the VLV outputs
on the Main Board. Refer to the diagram on page 8 for the location of valve connectors (VLV) on the OmniLogic Main Board. Record all connections in the
Connection Table on page 8.

Heater Control
Like the OmniLogic, the HLEXPAND provides a set of 4 low voltage dry contact relays that can be connected to most gas heaters or heat pumps with 24V control
circuits. When used with the optional Input/Output Expander Board (HLIOEXPAND), 8 dry contact relays are available. Refer to the diagram below for a generic
heater connection. 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 information on the fol-
lowing pages for more details on the connection to several popular heaters. Refer to the diagram on page 8 for the location of heater connections (LVR) on the
HLEXPAND 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 dry contact heater output per the diagram below. Many internal parts of the heater can get very hot--see the heater manufacturer’s recommenda-
tions 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.

External Input Interlock
Like the OmniLogic’s External Input Interlock, the HLEXPAND’s input provides a means to turn the filter pump or other component on/off when certain condi-
tions exists. A normally open or normally closed on/off external device must be connected to the HLEXPAND as shown below. After properly configuring the
OmniLogic (see Configuration Wizard in the HLBASE Installation Manual), the filter pump and/or desired pool component will be forced on or off when the device
is active. Record all connections using the table on page 8.
HL-CHEM ORP and pH Sensing Kit
Plug in the connector from the HL-CHEM into one of the Low Speed Bus connectors on the HLEXPAND’S Main Board as shown below. Refer to the HL-CHEM
manual for complete installation instructions.

Ethernet Connections
Connect the supplied 15 ft. Ethernet cable from the HLEXPAND to the OmniLogic. Loop the cable through the supplied ferrite bead as shown below.
If web enabled devices such as a PC, laptop, tablet or phone will be used to access the OmniLogic, an Ethernet connection must also be made to the home
router. Use outdoor rated Cat5e or Cat6 Ethernet cable and run a loop through the additional ferrite bead as shown in the diagram. Connect one end to the
HLEXPAND and the other to an available LAN port (not WAN) on the home router. If running Ethernet cable between the HLEXPAND and home router is impracti-
cal, a Hayward HLWLAN can make a wireless connection to the home router instead (see below).
Flow Switch
The flow switch cable plugs into the flow switch connector on the Main Board as shown on page 6. Ensure that the connector catch “snaps” in order to provide
a reliable connection.
TurboCell
Only applicable if the chlorinator function is enabled for an additional body of water. The TurboCell should be plugged in AFTER the HLEXPAND deadfront panel
is installed. Refer to page 6 for the location of the chlorinator cell connector.
HLIOEXPAND
The HLIOEXPAND is design to slide between guide rails and insert into a dedicated slot on the HLEXPAND Main Board. At startup, the HLEXPAND will discover
the HLIOEXPAND and its inputs/outputs can be configured within the OmniLogic’s Configuration Wizard. Refer to the HLIOEXPANDER manual for specific
installation instructions.
HLRELAYBANK
Offering four additional high voltage relays, the HLRELAYBANK is a relay kit accessory designed to install next to the four onboard relays in the HLEXPAND (see
page 8).After installing the HLRELAYBANK, a wire connection must be made at the HLEXPAND Main Board. At startup, the OmniLogic will detect the HLEXPAND’s
HLRELAYBANK and allow the user to configure the additional relays in the Configuration Wizard. Refer to the HLRELAYBANK manual for installation instructions.
HLRELAY
The HLRELAY is a single high voltage relay designed to be mounted in the #9 and/or #10 positions (page 8). After installing the HLRELAY, a wire connection
must be made at the HLEXPAND Main Board. At startup, the OmniLogic will detect the HLRELAY and allow the user to configure the additional relay(s) in the
Configuration Wizard. Refer to the HLRELAY manual for installation instructions.
HLWLAN
The HLWLAN can be mounted up to 25 ft. away from the HLEXPAND and requires an Ethernet connection to the HLEXPAND as well as a power connection to
the HLEXPAND Main Board. Refer to the HLWLAN manual for detailed installation instructions.

System Startup
Before powering up the HLEXPAND, check the following and then replace the deadfront panel:
• Properly rated circuit breakers are installed in the HLEXPAND subpanel.
• All wiring is performed according to NEC and local codes.
• The HLEXPAND is properly grounded and bonded.
NOTE: The OmniLogic deletes programmed Themes when new hardware is discovered. If the OmniLogic has already been in service before adding the HLEX-
PAND, any programmed Themes will be lost at startup. You’ll need to reprogram Themes after configuring the OmniLogic for use with the HLEXPAND.
Power up the OmniLogic HLBASE and HLEXPAND. At the local terminal, confirm that the OmniLogic has discovered the HLEXPAND in “System Info” as shown
below:
Firmware Upgrade
After communication is confirmed, the firmware on both units should be updated (even if the OmniLogic has been in service). Firmware is the basic operating
system and both the OmniLogic and HLEXPAND were shipped with versions of firmware that were available at the time of release. There may be a newer version
available and if so, we encourage you to upgrade. Also, if you have experienced problems, Hayward Technical Support may advise you to upgrade your firmware.
The procedure for upgrading firmware when using an HLEXPAND is to upgrade the OmniLogic first, then upgrade the HLEXPAND. Any wired or wireless remote
controls should also be upgraded. For instructions on how to upgrade firmware, refer to the procedure shown in the OmniLogic Operation Manual.

Configuration
The HLEXPAND can now be configured. Refer to the OmniLogic Installation manual for configuration information. If the OmniLogic has been in service before the
HLEXPAND has been installed, you can edit the existing OmniLogic configuration. For new installations where the OmniLogic and HLEXPAND have been installed
together, run the Configuration Wizard. Both methods are explained in the OmniLogic’s Installation manual.
When assigning equipment to relay and valve outputs or selecting sensors and external switches, prefixes are given to help identify the location of each. Refer
to the information below.
MP - inputs and outputs included in the HLBASE OmniLogic
RB - additional high voltage relays when an optional HLRELAYBANK has been installed in an OmniLogic
IO EXPANDER - additional low voltage relays and sensor/ext switch inputs when an optional IOEXPANDER has been installed in an OmniLogic
EPG0.MP - inputs and outputs included in the HLEXPAND Expansion Panel
EPG0.RB - additional high voltage relays when an optional HLRELAYBANK has been installed in an HLEXPAND
EPG0.IO EXPANDER - additional low voltage relays and sensor/ext switch inputs when an optional IOEXPANDER has been installed in an HLEXPAND
After configuration, refer to the OmniLogic Operation manual for Operation instructions. Test that all pool equipment is operating properly.
