INSTALLATION INSTRUCTIONS
CONTROLLER INSTALLATION
Find a suitable location to mount the control
box The controller should be installed out of
direct weather and no closer than 3 meters
from the water’s edge Lift up the two
mounting tabs and use two appropriate
screws to mount the control box to the wall,
keeping in mind that the power cable is 1 8m
long and should be plugged directly into a
general power outlet, not into an extension
lead
The solar pump plugs into the 240Vac socket
marked as PUMP
The pool sensor must be fitted into the
suction line of the pump, as close to the pool
as practical, preferably in a position out of
direct sunlight It is recommended that a
14 5mm hole be drilled in the PVC pipe, this
can be carried out using a Dontek PD01
grinding drill or a small pilot hole can be
drilled and a 14 0mm drill-bit used spinning
in a counter clockwise direction to minimize
the chance of shattering pipe Insert the
grommet into the pipe and gently push in the
blue/grey sensor barb The blue sensor plug is
to be fitted to the plug socket marked POOL
DO NOT cable-tie or tape sensor wires to
mains power, In some cases there is some
benefit to cable tie 30cm of wire from the
sensor to the pipe and insulate this section
(some ambient differences can travel up the
copper wire and affect the sensor reading)
Roof sensors must be fitted into a small piece
of solar collector or equivalent and attached
to the roof The best location is within an
arm'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 similar aspect of
the main 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
Keep in mind that it is of the utmost
importance to keep the roof sensor as short
as possible as this will assist in the longevity
of the sensor and controller in the event of
electrical storm activity and power surges
Sensor cables must not be run parallel to
power cables and run lengths should be less
than 50m Cable ties should be used to fasten
the sensor cable to the cold water inlet pipe
making sure that the ties are approximately
10mm from PVC fittings Cable ties should be
tightened only firm, over tightening can cause
breaks in the outer PVC if not careful If the
cable is to be run under ground a conduit
must 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 wire ends are
tinned with solder The red sensor plug is to
be fitted to the right hand socket marked
ROOF
CONTROLLER OPERATION AND SETTINGS
TEMPERATURE LIMIT
To change the temperature limit that
determines when to start or stop the pump
simply press (or hold) the UP button to
increase the desired temperature limit, the
DOWN button will decrease it
If the temperature limit is set below the
current pipe temperature then the pump is
automatically started for 3 minutes to test
the true pool water temperature
The controller will automatically choose to
run the pump based on solar gain (i e the sun
is shining & roof is hot) Once the desired
temperature is achieved the pump is stopped
and a four hour wait commences to ensure no
energy is wasted by unnecessarily starting
the pump If after 4 hours the roof is hot
enough then the pump may start to provide a
2nd heating cycle, if not then the “waiting for
roof to warm” message will appear If the pool

achieves temperature limit during the 2nd
heat cycle then it will start an economy/sleep
mode, which will prevent the pump from
starting for the rest of the day
MANUAL PUMP MODE
Holding the UP button to go above 40°C will
toggle the pump from Off to On or vice versa,
Manual mode will time out after 30 minutes of
being selected, with a default temperature
limit of 30°C
WINTER MODE
Holding the DOWN button to go below 20°C
will set the unit into WINTER mode, on
selection of winter mode the pump will run for
3 minutes and will repeat this every day at the
same time unless the power fails Should
there be an interruption to power then an
exception takes place to prevent the pump
starting at night, the sensors are tested to
check that the roof sensor is 5°C or more
above the pipe sensor, if this temperature
condition is not met the display will show
“waiting for roof to warm”, once the pump
starts the controller will wait 24 hours to
perform another unconditional flush of the
system
SUMMER MODE
Summer mode is the default mode of
operation; if tropical mode has been selected
you can change back to summer mode push
both buttons and when SUMMER is displayed,
released the buttons and use the up or down
buttons to set the desired temperature The
controller will automatically heat the pool to
this temperature when solar conditions are
favourable
TROPICAL MODE
To activate tropical mode, push and hold both
buttons and when “TROPICAL” is displayed,
release the buttons and use the up or down
button to set the desired temperature In
tropical mode the controller will attempt to
heat the pool, if the pool exceeds the
temperature limit while heating then the
controller turns off the pump and waits for
the roof to cool so the controller can cool the
pool down by dissipating the heat on the cold
roof (most likely to occur at night) In tropical
mode the controller attempts to keep the
pool at the temperature limit by either
heating or cooling as required
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
items are retained & the clock (if used)
will keep time for up to 14 days
3 The sensor cable with the red trace is the
positive and is usually fitted to the right
hand side of the plug when looking at the
plug screws, incorrect polarity may be
displayed as a short circuit fault
4 If the controller has stopped pumping and
is displaying a higher temperature than
expected it may be caused by a pump
which is failing to prime, check the pump
and if necessary prime the pump as per
the pump manufacturers’ instructions
then reset the controller by turning it
off/on
5 Maximum rated output load for the 240V
socket is 9 98 Amps / 2395 Watts
6 Degree of protection against moisture:
IP23
