INSTALLATION INSTRUCTIONS
CONTROLLER: Find a suitable location to ount the control box*radio note. The controller should be
installed out of direct weather and no closer than 3 eters fro the water’s edge. Lift up the two
ounting tabs and use two appropriate screws to ount the control box to the wall, keeping in ind
that the power cable is 1.8 long and should be plugged directly into a general power outlet, not into
an extension lead. Do not drill through the box.
SOLAR PUMP: The solar pu p plugs into the left side 240Vac socket arked as PUMP. Note that the
solar pu p can only operate when the FLOW switch detects water flow.
FLOW SWITCH: The Flow switch is fitted in the PVC pipe after the filter and before the take-off T; it
ust be ounted at the top of the pipe with the arrow atching the direction of water flow. If a
pressure switch is used it ust be ounted before the filter.
TEMPERATURE SENSOR: The pool te perature sensor ust be fitted into the suction line of the
filtration pu p, as close to the pool as practical, preferably in a position out of direct sunlight. It is
reco ended that a 14.5 hole be drilled in the PVC pipe, this can be carried out using a Dontek
PD01 grinding drill or a s all pilot hole can be drilled and a 14.0 drill-bit used spinning in a
counter clockwise direction to ini ize the chance of shattering pipe. Insert the gro et into the
pipe and gently push in the blue sensor barb. The blue sensor plug is to be fitted to the plug socket
arked POOL, in so e cases there is so e benefit to cable tie 30c of wire fro the pool
te perature sensor to the pipe and insulate this section (so e a bient differences can travel up the
tinned copper wire and affect the sensor reading).
All temperature sensor cables must NOT be run parallel to po er cables and should never
be cable tied to po er cables. All cable run lengths should be less than 50 if possible. Cable ties
should be used to fasten the sensor cable to the cold water inlet pipe aking sure that the ties are
approxi ately 10 fro PVC fittings. Cable ties should be tightened only fir , over tightening can
cause breaks in the outer PVC if not careful. If the cable is to be run under ground a conduit ust be
used to protect the wire and there is to be no cable joins within, conduit ends must be sealed to
prevent water ingress.
Any excess cable should be removed and re-fitted ensuring that the ire ends are tinned
ith solder.
REMOTE TEMPERATURE ROOF SENSOR:
The roof te perature sensor ust be fitted into a s all piece of solar collector or equivalent and
attached to the roof. The best location is within an ar s length of the gutters edge of the house or
shed as long as the sensor end is not shaded and is on a roof of si ilar aspect of the ain collector. It
must not be fitted on top of the solar collector or fitted to high points on the roof like Ridge Capping
as false readings will be detected.
This unit has been designed to eli inate the need to run a te perature sensor cable fro the solar
controller to the roof; this is replaced by a solar powered trans itter that trans its the roof
te perature. The roof te perature sensor cable is connected on the inside of the radio re ote
te perature trans itter in a screw in socket. Test for site suitability (*radio note) then ount the radio
re ote te perature trans itter on the gutter ensuring the solar panel (PV) faces north and the
antenna points up (Vertical), if the antenna faces down then water ay enter the box through the
power entry / sensor entry hole and void the warranty.
*RADIO NOTE: RADIO TRANSMITTER SPECIAL CONSIDERATIONS:
Do not per anently fix the radio trans itter until good reception is achievable (See site test); do not
ount the Aquasun 3 in a position where reception of radio signals ay be difficult, avoid ounting
near other electrical equip ent (try a site test with a FM radio or Mobile phone).
The range is 100 with no obstructions and with no interference fro other trans itters or sources of
electrical noise. Trans ission ay not occur through objects such as steel, alu iniu , re-enforced
concrete and large bodies of water (e.g. pu p roo under a pool). Line of sight is the ideal situation
but not always possible, the antennas should always re ain vertical. Echo cancellation or ghosting
ay occur, which will prevent the signal being received reliably. If the Aquasun 3 is to be installed in a
etal shed there ay be reception issues and the controller ay need to be optioned with a re ote
antenna or oved outside.

SITE TEST:
Place the radio trans itter in the approxi ate location. Select test ode on the Aquasun 3 by holding
the DOWN button for 3 seconds while you apply power, this activates a ode where only roof
te perature trans issions are shown. Once you release the down button the Aquasun 3 screen
indicates RX TEST.
Verify that every 5 seconds the LCD displays the te perature (e.g. TEST 32°). Check that this
sequence is repeated for about half a inute and ensure no trans ission is issed. If a trans ission
is issed it ay be due to an echo or ghosted signal, ove the location of the radio trans itter or the
location of the Aquasun3 and retest. If no trans ission is issed ount the trans itter and repeat
the test, check that no trans ission is issed for 2 inutes.
Turn OFF power to the Aquasun 3 and then per anently ount the radio trans itter to the facia
board. Return to the Aquasun 3 restart the RX TEST and ensure it continues to receive the
trans ission, ove the location of the Aquasun 3 if required. Per anently ount the Aquasun 3 when
satisfied that the Aquasun 3 is receiving the trans issions consistently.
During nor al operation the software allows for issed trans issions, but when ore than 50
inutes elapse without a trans ission then the te perature value will ti eout and will be indicated
by the “Waiting for roof trans ission” essage.
REPORTED TRANSMITTER FAULTS
If the following essages are displayed, then action is to be taken to rectify the fault(s)
"WAITING FOR ROOF TRANSMISSION"
The Aquasun 3 cannot receive a roof te perature fro the radio trans itter or ore than 50 inutes
have elapsed since the last trans ission, check installation is per instructions.
"ROOF SENSOR DISCONNECTED OR OPEN CIRCUIT"
Check that the te perature sensor is fir ly connected to the ter inals. If the cable has been tri ed
ensure the ends have been tinned with solder. Cable joints ust also be soldered and sealed
(preferably with heat-shrink). An unbroken but da aged cable can also cause this fault.
"ROOF SENSOR SHORT CIRCUIT OR REVERSED"
If the cable has been joined or shortened be aware that the white side of the cable is positive, inside
the trans itter there is a white + on the circuit board indicating where positive is to be connected.

OPERATING INSTRUCTIONS
DESCRIPTION: The AquaSun 3FRP is a pre iu auto atic solar controller with te perature
adjust ent, anual, winter and tropical ode features. This unit is fitted with flow detection; the
solar pu p can only operate if the flow or pressure switch detects water flow.
TEMPERATURE LIMIT:
To adjust the pool li it si ply press the UP button to increase or the DOWN button to decrease the
desired te perature.
The controller will auto atically choose to run the pu p based on solar gain (i.e. sun shining & roof is
hot), once the pools desired te perature is exceeded by ½°C the pu p is stopped until the pool
te perature drops ½°C below the te perature li it setting.
MODE of operation:
Pressing the SELECT7 button once will display the current ode of operation, pressing it again or
holding it will select the next available ode of operation.
The available odes are SUMMER, MANUAL, WINTER and SETTINGS.
Summer mode is the nor al operating ode for heating the pool.
Manual mode is for testing the pu p installation on a cold or cloudy day. Once anual ode is
selected the pu p will start if it has been off, or stop if it has been on (running). After 30 inutes
anual ode will ti e-out and return to Su er Mode with a default te perature li it of 30°C. Note
that Manual ON requires an operating filtration pu p (flow).
Winter mode of operation is for off-season aintenance or if pool heating is not required (AWAY
MODE). This is a better option than turning off the controller as it will flush treated pool water through
the solar syste as well as prolong pu p bearing and echanical seal life. The pu p will run for 3
inutes once a day 3 inutes after the filtration pu p has started.
Settings mode is for setting the unit into ti e-clock operation.
When you select this option you will be asked if you wish to use the clock feature (CLK? ON/OFF).
If you select OFF then the controller will not work as a ti e-clock odel and will allow the solar pu p
to run whenever there is solar heating available and if the filtration pu p is operating. If you select
ON you will be pro pted to set the ti e of day, the controller will work in ti e-clock ode and the
solar pu p is prevented fro starting outside of the set hours. Set the ti e of day in 24 hour for at,
note there is an AM/PM indication to avoid incorrect settings. Seconds are auto atically set to zero.
Once the ti e is set select the START hour fro 6a till noon, default is 9a which eans the solar
pu p cannot start before 9a .
Now select the END hour fro 15 (3p ) till 21 (9p ), default is 19 (7p ) which eans the solar
pu p will stop at 7p .
INSTALLER SETTINGS:
To select these features, hold the DOWN button then press SELECT.
Adjustable differential: Special note: Adjusting these values to any setting other than the defaults
ay adversely affect the perfor ance of this controller.
The first ite pro pted is to set the solar gain start te perature (RUN° x) this setting allows the
pu p to start if the roof te perature exceeds the pool te perature by this value, adjust with the
UP/DOWN button, press SELECT to accept. Next you will be pro pted to set the differential hysteresis
(END° x) which turns the pu p off when roof te perature is less than the pipe te perature plus this
value, adjust with the UP/DOWN button, press SELECT to accept. Default values are 8° for RUN and 4°
for END, these are the opti al values for axi u efficiency, so e coastal locations ay benefit
fro a reduced run value of 6°C for RUN and 4°C for END. Re-adjust the te perature li it if required.

Factory Test:
To run the factory test, hold the SELECT button when first applying power, the unit will perfor a
series of self-diagnostic functions with the pu p running.
The unit will display FLOW or NO FLOW, with the filtration and solar pu p running ensure FLOW is
displayed, for pressure switch operation adjust the pressure switch until FLOW is displayed (ensure
the filter is clean).
Press SELECT and if there are any faults they will be reported on the display before the unit restarts
into nor al operation.
Note: that this will force all settings to a factory default state. Re enable time clock if required also
reset the Load start value, temperature limit and operating mode to their required settings.
NOTES:
1. If a sensor fault is detected the controller will display which sensor failed (POOL and/or ROOF)
and the type of failure.
2. After a power outage all configurable ite s are retained & the clock (if used) will keep ti e for
up to 14 days.
3. The sensor cable with the red trace is the positive and is fitted to the right hand side of the plug
when looking at the plug screws, incorrect polarity ay be displayed as a short circuit or
reversed fault.
4. When the FLOW switch detects the filtration pu p starting it will perfor a 3 inute checking
sequence that ensures there is suitable te perature & water flow before the solar pu p will
start. When the filtration pu p is stopped the solar pu p is also stopped.
5. Maxi u rated output load for the 240V socket is 9.98 A ps / 2395 Watts.
6. Degree of protection against oisture: IP23
7. SELECT ay be labeled ENTER on so e odels.
