EXTRAS – SOLD SEPARATELY
Pool and Spa Combination systems require a “SPA FLOW SWITCH” to be fitted to the spa suction line. This is so that the system is able to determine which body of water is being treated by the chlorinator. It is also required for the solar, heater and automatic valve actuator functions to operate correctly.
The Integrated Solar controller requires two additional temperature sensors. One is a roof temperature sensor for measuring available solar energy, and the other is for the solar collector water inlet temperature.
Automatic Valve Actuators can be fitted for automated control of pool and spa flow control valves, as well as up to two additional valves for other functions such as solar
control, in-floor cleaning systems, or water features, etc.

Solar heating will only be used in SPA mode if the SOLAR configuration item HEAT SPA is set to YES.

INSTALLATION GUIDE

MOUNTING LOCATION
The EXP module must be mounted on a vertical wall or post, with the power sockets facing downwards.
The unit will need to be mounted within approximately 2.5 meters of the Pool Lab Chlorinator control box to allow connection of the data cable. Both units must be mounted outside the pool zones as defined by AN/NZS 3000:2000.
As a general rule for swimming pools, the Pool Lab units must be mounted at least 3.5 meters away from the inside edge of the pool to be clear of the pool zones, and at least
45cm above the ground to protect the outlet sockets from water being splashed up from the ground.
The EXP module should be mounted so that the equipment can be easily connected.
Masonry plugs and screws are provided with the mounting bracket, and the screws provided are also suitable for mounting to timber.
Secure the mounting bracket in place with the slotted edge to the top, and ensure the bracket is level and firmly secured before mounting the EXP module onto it.
The bracket at the back of the EXP module hooks over the slots on the top edge of the mounting bracket. Secure the EXP module to the bracket with the M3x16mm screws
provided.

Mounting on Brick or Masonry Wall – Example

  • Use the bracket as a stencil to mark the hole locations. Avoid locating holes near the edge of bricks or in mortar joints where possible. Ensure the bracket is level and the slotted edge is to the top.
  • Use a hammer drill with a 6.5mm masonry bit, and drill holes to a depth of at least 40mm.
  • Use a hammer or mallet to drive the masonry plugs provided into the drilled holes.
  • Attach bracket to the wall with the screws provided, and ensure screws are firmly tightened using a Phillips Head screwdriver, or clutched drill / driver with a PH2 bit.
  • Mount the EXP module by hooking the bracket at the back of the unit into the slots in the top of the bracket. Secure the unit to the bracket with 2 x M3x16mm screws
    provided.

ELECTRICAL POWER CONNECTION
EXP5 models are fitted with a power cord for connection to a standard 10 amp power outlet. The unit is protected from overload by a 10 amp manual reset circuit breaker.
EXP10 models require an electrician to complete the electrical power connections before commissioning the unit. The power input is divided into two 15 amp circuits with a manual reset circuit breaker on each circuit. Power may be provided by either 1 x 32 amp circuit, or 2 x 16 amp circuits. An isolator switch must also be installed nearby.
The Pool Lab EXP module is intended to be powered at all times. Power should only be turned off when the system is not in use for an extended period of time.
TEMPERATURE SENSORS FILTRATION CIRCUIT TEMP SENSOR
The Pool Lab EXP is shipped with 1 x temperature sensor included for the filtration circuit.
This sensor should be installed on the filtration system pipework before any solar or other heating equipment. This sensor is required for the integrated gas heater controller to function, and also enables water temperature display.

  • Find a suitable location as close to the EXP module as practical.
  • If the pipework is below water level, close isolation valves.
  • Drain water from the pipework if necessary.
  • Drill a 10mm hole in the pipe, and insert the temperature sensor. Fix in place with the gear clamp provided.
  • Run the temperature sensor wire to the EXP module terminal block at the base of the unit. Fix wiring to the pipework with cable ties where necessary.
  • Trim length if required.
  • Connect temperature sensor wires to terminals marked FILTER CIRCUIT TEMP SENSOR (any polarity).

Note: The terminal block is removable to make connection easier.
SOLAR TEMP SENSORS
If the integrated solar controller is to be used this will require 2 x additional temperature sensors which are sold separately.
The sensor with the 3m lead and o-ring must be installed on the pipework on the inlet side of the solar collector in a location where water does not drain from the system. Generally the inlet side of the solar pump is an ideal location. This sensor should be connected to the terminals marked SOLAR INLET TEMP SENSOR.
The other sensor with a 15m lead should be installed away from the pipework in a location with similar sunlight exposure as the solar collector. A small piece of solar matting material is included in the kit. Insert the sensor into one of the solar matting tubes and attach the matting in location with silicone adhesive or similar. This sensor should be connected to the terminals marked SOLAR ROOF TEMP SENSOR.
HEATER CONNECTION
Where the integrated gas heater controller is to be used, a normally-open relay contact is provided on the terminal block for heater control. Alternatively the auxiliary power outputs can also be configured as a means of controlling a heater if required. Consult your heater documentation for the recommended connection and control method. Some heaters may require configuration settings to be changed for external temperature control. It is recommended to set the heaters internal temperature control to the maximum allowed setting, otherwise the water temperature will be limited to the setting on the heater.
The integrated gas heater controller can also be used for heat pump or electric heating, although power will need to be provided separately for these.
AUTOMATIC VALVE ACTUATORS
For pool and spa combination systems, automated control of your pool and spa mode flow control valves requires 2 x 24VAC valve actuator motors mounted on compatible valves which are sold separately.
Some examples of valve actuator motors that are directly compatible with the Pool Lab EXP module are: Hayward Goldline GVA-24, Pentair CVA24, or Jandy JVA 2444 Valve Actuators.
These must be installed on the filtration pump inlet flow control valve, and the filtration circuit return flow control valves. Consult the valve actuator documentation for specific installation instructions.
It is recommended that a small amount of water flow to the spa when in POOL mode to maintain water quality in the spa. This is usually achieved by setting the cams inside the valve actuator to not completely close the spa return line.
Care should be taken when installing to ensure that flow is not blocked at any time while the valves are in motion.
AUXILIARY EQUIPMENT
Power outlet sockets are provided at the bottom of the unit for connection to auxiliary equipment. Each connected auxiliary must be configured to suit it’s application before
use. Care must be taken to ensure the combined current of connected equipment does not exceed the circuit breaker rating.
EXP5 models are fitted with a 10 amp circuit breaker.
EXP9 models are fitted with a 20 amp circuit breaker.
SYSTEM CONFIGURATION
Once the Pool Lab Chlorinator has detected that the Pool Lab EXP is connected, the MAIN MENU will have options relating to your EXP configuration and settings.
For your connected equipment to operate as intended, it is important that all configuration items are set to suit your system prior to use.
Authority Level
Most system configuration items are protected against accidental changes with a user AUTHORITY level. Before you can change any system configuration items, you must first set the AUTHORITY level to “INST” (INSTALLER).

  1. Go to the MAIN MENU (press and hold VIEW for 3 seconds)
  2. Navigate to SYSTEM CONFIG, and press VIEW
  3. Navigate to AUTHORITY, and press VIEW
  4. Press VIEW again to edit the AUTHORITY level
  5. Use the UP / DOWN buttons to change the AUTHORITY level to “INST”
  6. Press VIEW to save the changes
  7. Press BACK once to return to the SYSTEM CONFIG menu

The AUTHORITY level setting will automatically revert back to USER after 5 minutes of inactivity, or it can be changed back to USER manually at any time.
Pool and Spa Volumes
The Pool Lab EXP uses the pool and spa volumes to determine if you have a pool only,
spa only, or a pool and spa combination system. For systems where a Pool Lab ASP is
also installed these volumes are used to calculate chlorine and acid deliveries.
POOL VOLUME: 0 – 250 KL (Kilolitres)
eg. 50 KL = 50,000 Litres.
Round the value down to the nearest 5 Kilolitres (5000 Litres).
Include the volume of any additional catchment basins and balancing tanks.
If installed on a SPA ONLY system, set POOL VOLUME to ZERO
SPA VOLUME: 0 – 50 KL (Kilolitres)
Round the value down to the nearest 0.1 Kilolitres (100 Litres).
If installed on a POOL ONLY system, set SPA VOLUME to ZERO
Heater Configuration
HEAT POOL: (YES / NO)
This will allow the gas heater to operate when the system is in POOL mode.
HEAT SPA : (YES / NO)
This will allow the gas heater to operate when the system is in SPA mode.
Note: To disable the heater controller, set both HEAT POOL and HEAT SPA to NO.
COOL DOWN: (number of minutes)
Number of minutes required for the gas heater to cool down before allowing the filtration pump to turn off. This can be useful to dissipate excess residual heat which may cause nuisance tripping of the over-temperature limit switch, or in some cases damage to the plumbing.
Note: The COOL DOWN timer is canceled if the filtration mode is set to OFF.
Note: The COOL DOWN timer does not affect AUX outputs configured as HEATER unless they are interlocked to the filtration pump. (See AUXILIARY CONFIGURATION)
FILT O’RIDE: (YES / NO)
The filter override function will allow the heater controller to override the filtration timer periods when the filtration system is in AUTO mode. This will allow the filtration pump and gas heater to run beyond the normal filtration timer periods until the set temperature is achieved.
CAUTION: If using this setting with HEAT POOL set to YES, you must ensure the heater is capable of achieving the set temperature within a reasonable time period. The system may run the heater indefinitely if it is unable to achieve the set temperature.
NOTE: This function will not initiate a start up of the filtration pump outside of normal timer periods, it will only allow the filter pump to run on beyond the timer periods.

Solar Configuration

HEAT POOL (YES / NO)
For non-isolated solar systems such as retro-fit / solar boost pump or valve operated solar, this will allow the solar heating system to operate when the system is in POOL mode. For ISOLATED solar systems this will allow the solar heating system to heat the pool in either POOL or SPA mode, and the solar controller will be bound to the pool set temperature.
HEAT SPA (YES / NO)
This will allow the solar heating system to operate when the system is in SPA mode.
Note: To disable the solar heating controller, set both HEAT POOL and HEAT SPA to NO.
ECON MODE (ON / OFF)
Economy mode will give priority to solar heating when solar heat is available. This will only take effect when both SOLAR and HEATER are in use at the same time.
If the solar system is isolated, then this will only affect operation in POOL mode.
This setting is particularly useful for saving energy when a combination of gas and solar heating is used. The gas heater will only operate when there is insufficient solar heat
available.
ISOLATED (YES / NO)
Set to YES if the solar heating system is isolated from the filtration system, and can be run independently of the filtration system.
For valve controlled solar systems or solar boost (retro-fit) systems that require the filtration pump to be running to operate, set this to NO.
When set to YES the solar controller will always use the temperature target set for POOL mode, and will allow solar heating of the pool in either POOL or SPA mode.
When set to NO the solar controller will select the temperature target based on whether the system is in POOL or SPA mode. If the system also has a gas heater fitted, then the gas heater will be inhibited for a short time every time the solar turns ON – this is to allow some time for air to evacuate the solar system and protect the gas heater from thermal shock.
FILT O’RIDE (YES / NO)
The filter override function will allow the solar controller to override the filtration timer periods when the filtration system is in AUTO mode. This is useful for solar systems that require the filtration pump to be running, as it will allow for solar heating outside the filtration timer periods.
The override function will only operate when the solar system is on, and there is sufficient solar heat available, and the water temperature is below the set target.

Auxiliary Configuration

Each auxiliary output can be configured to one of the following functions:
DISABLED: Output disabled, and associated controls hidden.
ENABLE: General purpose output with timer and ON – OFF – AUTO control.
SOLAR: Solar pump output controlled by the integrated solar controller.
HEATER: Heater output controlled by the integrated heater controller.
FILTER: Output synchronized with the filtration pump.
Alternatively, auxiliary outputs can be placed into the following pre-set labeled groups:
POOLLIGHT – SPA LIGHT – SPA BOOST – SPA BLOWER INFLOOR – CLEANER – FOUNTAIN
Note: Multiple auxiliary outputs can be assigned to a single group. Each group has its’ own timer and ON – OFF – AUTO control, and outputs assigned to that group will be
synchronized.
INTERLOCK ( YES / NO )
If set to YES this output will only be allowed to operate when the filtration pump is running.
If set to NO this output will operate independently.
Ensure this is set to YES for any pumps that require the filtration system to be running.
Eg. Retro-fit solar system boost pumps.
ALLOW w/ SPA ( YES / NO )
If set to NO this output will be forced off when the system is in SPA mode.
This feature can be useful for preventing certain nuisance situations when heating the spa.
For example, prevent in-floor cleaning systems with heads in the spa from operating, or prevent solar systems that return water to the spa from operating.
Valve Configuration
Valve 1 and 2 have a fixed configuration, and will always operate as pool / spa suction and return flow control valves.
Valve 3 and Valve 4 can be configured to one of the following functions:
DISABLED: Valve disabled, and associated controls hidden.
ENABLE: General purpose valve with timer and P1 – P2 – AUTO control.
SOLAR: Solar flow diverter valve controlled by the integrated solar controller.
HEATER: Heater flow diverter controlled by the integrated heater controller.
POOL/SPA: Valve synchronized with POOL / SPA mode (same as Valve 1 & 2).
Alternatively, valves can be placed into the following pre-set labeled groups:
INFLOOR – CLEANER – FOUNTAIN INTERLOCK ( YES / NO )
If set to YES this valve will only be allowed to operate when the filtration pump is running.
If set to NO this valve will operate independently.
ALLOW w/ SPA ( YES / NO )
If set to NO this output will be forced to P1 (Position 1) when the system is in SPA mode.
This feature can be useful for preventing certain nuisance situations when heating the spa.
For example, prevent in-floor cleaning systems with heads in the spa from operating, or prevent solar systems that return water to the spa from operating.

INSTALLATION SCHEMATIC

The following schematic diagram shows an example of a typical installation.
This example shows a pool and spa combination with a gas heater and integrated solar.
The ASP must be mounted before any heaters or solar equipment, and after the filter.
The ASP must be mounted before the chlorine cell, and before the acid injection point.
The SPA FLOW SWITCH is mounted on the SPA SUCTION line. This is only required for pool and spa combination systems.

WIRING
Spa Flow switch (Pool & Spa Combination Systems only) must be connected to the Pool Lab Salt Chlorinator port marked “SPA FLOW”
Peristaltic Acid Pump must be connected to the Pool Lab Salt Chlorinator port marked “ACID PUMP”.
The Pool Lab ASP power/data cable must be connected to the Pool Lab Salt Chlorinator port marked “ASP”.
