INSTALLATION INSTRUCTIONS
CONTROLLER INSTALLATION
Find a suita le location to mount the control
ox. The controller should e installed out of
direct weather and no closer than 3 meters
from the water’s edge. Lift up the two
mounting ta s and use two appropriate
screws to mount the control ox to the wall,
keeping in mind that the power ca le is 1.8m
long and should e 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 e fitted into the
suction line of the pump, as close to the pool
as practical, prefera ly in a position out of
direct sunlight. It is recommended that a
14.5mm hole e drilled in the PVC pipe, this
can e carried out using a Dontek PD01
grinding drill or a small pilot hole can e
drilled and a 14.0mm drill- it used spinning
in a counter clockwise direction to minimise
the chance of shattering pipe. Insert the
grommet into the pipe and gently push in the
lack sensor ar . The green sensor plug is to
e fitted to the plug socket marked POOL.
DO NOT ca le-tie or tape sensor wires to
mains power, in some cases there is some
enefit to ca le tie 30cm of wire from the
sensor to the pipe and insulate this section
(some am ient differences can travel up the
tinned copper wire and affect the sensor
reading).
Roof sensors must e fitted into a small piece
of solar collector or equivalent and attached
to the roof. The est 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
must notmust not
must not e fitted on
top of the solar collector or fitted to high
points on the roof like ridge capping as false
readings will e detected.
Keep in mind that it is of the utmost
importance to keep the roof sensor as short
as possi le as this will assist in the longevity
of the sensor and controller in the event of
electrical storm activity and power surges.

TEMPERATURE LIMIT
To adjust the pool limit simply press the UP
utton to increase or the DOWN utton to
decrease the desired temperature.
The controller will automatically choose to
run the pump ased on solar gain (i.e. sun
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 y cycling the pump.
If after 4 hours the roof is hot enough then
the pump may start to provide another
heating cycle and if the desired temperature
is reached again then no heating will occur
until the next day unless the controller is
operating in time-clock mode where heating
can occur until solar lockout time (09:00 till
19:00)

MODE OF OPERATION
Pressing the SELECT utton once will display
the current mode of operation, pressing it
again or holding it will select the next
availa le mode of operation.
The availa le modes are SUMMER, MANUAL,
TROPICAL or WINTER.
Summer mode
Summer modeSummer mode
Summer mode is the normal operating mode
for heating the pool.
Winter mode
Winter modeWinter mode
Winter mode of operation is for off-season
maintenance or if pool heating is not required
(AWAY MODE) . This is a etter option than
turning off the controller as it will flush
treated pool water through the solar system
as well as prolong pump earing and
mechanical seal life. The pump will run for 3
minutes each day from when the winter mode
was selected or at 10am if the time-clock
mode was selected.
Tropical
Tropical Tropical
Tropical mode
modemode
mode is for situations where the
pool water overheats eyond the set
temperature limit due to direct heating from
the sun. The unit will attempt to sample the
pool water when solar gain is availa le and if
after 3 minutes the pool is a ove the desired
temperature limit then the controller will wait
until the roof is 4°C cooler than the pool
temperature, the pump is then started to cool
the pool (this will most likely occur at night).
Manual mod
Manual modManual mod
Manual mode
ee
e is for testing the pump
installation on a cold or cloudy day. Once
manual mode is selected the pump will start
if it has een off, or stop if it has een on
(running). After 30 minutes manual mode will
time-out and return to Summer Mode with a
default temperature limit of 30°C
Settings mode
Settings modeSettings mode
Settings mode is for setting the unit into
time-clock operation.
When you select this option you will e asked
if you wish to use the clock feature (CLK?
ON/OFF).
If you select OFF then the controller will not
work as a time-clock model and will prevent
starting the pump to sample at night ased
on a sequence of events.
If you select ON you will e prompted to set
the time of day, the controller will work in
time-clock mode and the solar pump is
prevented from starting outside of the set
hours (unless tropical mode is selected). Set
the time of day in 24 hour format, note there
is an AM/PM indication to avoid incorrect
settings. Seconds are automatically set to
zero.
Once the time is set select the START hour
from 6am till 12 noon, default is 9am which
means the solar pump cannot start efore
9am.
Now select the END hour from 15:00 (3pm)
until 21:00 (9pm), default is 19:00 (7pm)
which means the solar pump will stop at 7pm.
INSTALLER SETTINGS - ADJUSTABLE
DIFFERENTIAL & ANTI-FREEZE/BOIL
FEATURES:
Special note: Adjusting these values to any
setting other than the defaults may adversely
affect the performance of this controller. To
select these features, hold the DOWN utton
then press SELECT. When you select this
option you will e prompted to set the solar
gain start temperature (RUN° x) this setting
allows the pump to start if the roof
temperature exceeds the last valid pool
temperature or pipe temperature y this
value, adjust with the UP/DOWN utton, press
SELECT to accept. Next you will e prompted
to set the differential hysteresis (END° x)
which turns the pump off when roof
temperature is less than the pool
temperature plus this value, adjust with the
UP/DOWN utton, press SELECT to accept.
Default values are 8° for RUN and 4° for END,
these are the optimal values for maximum
efficiency, some coastal locations may
enefit from a reduced run value of 6°C for
RUN and 4°C for END.
The next item is anti-freeze, you will e
prompted y FRZ? ON/OFF, adjust with the

UP/DOWN utton, press SELECT to accept. If
you select OFF then you will e prompted to
the anti- oil selection. If you selected ON
then you will e prompted to adjust the anti-
freeze start temperature point as follows;
“FREEZE° x “adjust with the UP/DOWN utton,
press SELECT to accept. Once the roof
temperature gets to the anti-freeze setting or
elow then the pump will e turned on for 3
minutes then turn off for 30 minutes, this
sequence will repeat until the roof
temperature rises a ove the anti-freeze
temperature.
The next item is anti- oil, you will e
prompted y BOIL? ON/OFF, adjust with the
UP/DOWN utton, press SELECT to accept, if
you select OFF then the a ove settings will e
saved and the unit will restart. If you selected
ON then you will e prompted to adjust the
anti- oil start temperature point as follows;
“BOIL °xx” adjust with the UP/DOWN utton,
press SELECT to accept. The unit will save the
new settings and restart. Once the roof
temperature gets to the anti- oil setting or
a ove then the pump will e turned on for 5
minutes then turn off for 15 minutes, this
sequence will repeat until the roof
temperature drops elow the anti- oil
temperature. The customer is to e made
aware that these features have een turned
on and that the controller must remain
turned on at all times.
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. Should power e interrupted for any
reason, the controller will resume normal
operation when power is restored, all
information will have een kept for up to
14 days.
3. Temperature sensor used with this unit is
digital and is accurate to 0.5°C, no
cali ration is required.
4. The sensor ca le with the thin trace is the
positive and is usually fitted to the right
hand side of the green plug when looking
at the plug screws, incorrect polarity will
e displayed as a short circuit or reversed
fault.
5. If the controller has stopped pumping and
is displaying a higher temperature than
expected it may e caused y 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 y turning it
off/on.
6. Maximum rated output load for the 240V
socket is either, 10 Amps / 2400 Watts, or
oror
or,
15 Amps / 3600 Watts. Please refer to the
unit’s rating la el.
