SL3 INSTRUCTIONS
DESCRIPTION:
The SL3 is an entry range automatic solar controller with temperature adjustment,
manual mode and winter mode features. Mode of operation and the temperature
limit setting are retained after a power outage.
CONTROLLER INSTALATION:
Find a suitable location to mount the control box. The controller must be installed out
of direct weather and no closer than 3 meters from the waters 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 black sensor barb. The green 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 arms 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 p r llel
to power c bles 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 c ble should be removed nd re-fitted ensuring th t the wire ends
re tinned with solder. The 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 DO N 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 DO N button to go below 20°C will set the unit into
INTER 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. Should power be interrupted for any reason, the controller will
resume normal operation when power is restored, all
information will have been kept.
3. Temperature sensor used with this unit is digital and is accurate
to 0.5°Celcius, no calibration is required.
4. The sensor cable 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 be displayed
as a short circuit fault.
5. 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.
6. Maximum rated output load for the 240V sockets is 10 Amps
2400 att.
