DESCRIPTION:
The SL6 Elite is a premium automatic solar controller with temperature adjustment,
manual, winter and tropical mode features. All configurable items are retained after a
power outage for up to 14 days.
CONTROLLER INSTALLATION:
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 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 24 Vac 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 PD 1 grinding drill
or a small pilot hole can be drilled and a 14. mm drill-bit 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 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 3 cm of wire from the sensor to the pipe and insulate this section
(some ambient differences can travel up the tinned 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 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 5 m if possible. Cable ties should be
used to fasten the sensor cable to the cold water inlet pipe making sure that the ties are
approximately 1 mm 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
sensor plug is to be fitted to the right hand socket marked ROOF.

TEMPERATURE LIMIT:
To adjust the pool limit simply press the UP button to increase or the DOWN button to
decrease the desired temperature.
The controller will automatically choose to run the pump based 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 by 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 ( 9: till 19: )
MODE of operation:
Pressing the SELECT button once will display the current mode of operation, pressing
it again or holding it will select the next available mode of operation.
The available modes are SUMMER, MANUAL, TROPICAL or WINTER.
Summer mode is the normal operating mode for heating the pool.
Winter mode of operation is for off-season maintenance 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 system as well as prolong pump bearing
and mechanical seal life. The pump will run for 3 minutes each day from when the
winter mode was selected or at 1 am if the time-clock mode was selected.
Tropical mode is for situations where the pool water overheats beyond the set
temperature limit due to direct heating from the sun. The unit will attempt to sample
the pool water when solar gain is available and if after 3 minutes the pool is above
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 mode is for testing the pump installation on a cold or cloudy day. Once manual
mode is selected the pump will start if it has been off, or stop if it has been on
(running). After 3 minutes manual mode will time-out and return to Summer
Mode with a default temperature limit of 3 °C
Settings mode is for setting the unit into time-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 time-clock model and will
prevent starting the pump to sample at night based on a sequence of events.
If you select ON you will be 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 before 9am.
Now select the END hour from 15: (3pm) until 21: (9pm), default is 19:
(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 button then press SELECT. When you select this option you will be 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
by this value, adjust with the UP/DOWN button, press SELECT to accept. Next you
will be 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 button, 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 benefit from a reduced run value of 6°C for RUN and 4°C for END.
The next item is anti-freeze, you will be prompted by FRZ? ON/OFF, adjust with the
UP/DOWN button, press SELECT to accept. If you select OFF then you will be
prompted to the anti-boil selection. If you selected ON then you will be prompted to
adjust the anti-freeze start temperature point as follows; “FREEZ° x “adjust with the
UP/DOWN button, press SELECT to accept. Once the roof temperature gets to the
anti-freeze setting or below then the pump will be turned on for 3 minutes then turn
off for 3 minutes, this sequence will repeat until the roof temperature rises above
the anti-freeze temperature.
The next item is anti-boil, you will be prompted by BOIL? ON/OFF, adjust with the
UP/DOWN button, press SELECT to accept, if you select OFF then the above settings
will be saved and the unit will restart. If you selected ON then you will be prompted
to adjust the anti-boil start temperature point as follows; “BOIL °xx” adjust with the
UP/DOWN button, press SELECT to accept. The unit will save the new settings and
restart. Once the roof temperature gets to the anti-boil setting or above then the
pump will be turned on for 5 minutes then turn off for 15 minutes, this sequence will
repeat until the roof temperature drops below the anti-boil temperature. The
customer is to be made aware that these features have been 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 be interrupted for any reason, the controller will resume normal
operation when power is restored, all information will have been kept for up to
14 days.
3. Temperature sensor used with this unit is digital and is accurate to .5°C, 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 or reversed 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 24 V socket is 1 Amps 24 Watt.
