Sunlover SL6E Operating Instructions Manual

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. Temperature sensors 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 fitted to the right hand side of the plug

when looking at the plug screws, incorrect polarity will be displayed as a short circuit or reversed
fault.

5. A filtration pump that uses too much current can bring up an OVERLOAD condition. Disconnect

power & check the condition of the filtration pump, this will prevent the solar pump from running.

6. When the auxiliary power socket detects the filtration pump starting it will perform a 3 minute

checking sequence that ensures there is suitable temperature & water flow before the solar pump
will start. When the filtration pump is stopped the solar pump is also stopped.

7. Pump load values displayed is relative to how much power is consumed by the pump, note that

variable speed pumps tend to display higher than expected values.

8. Maximum rated output load for the 240V socket is 10 Amps / 2400 Watts.

SL6E CD OPERATING INSTRUCTIONS

DESCRIPTION: The SL6E CD is a premium automatic solar controller with temperature adjustment, manual,
winter and tropical mode features. This unit is fitted with current detection on the auxiliary power socket;
the solar pump can only operate if the current load on the controllers auxiliary socket is within a certain
range (e.g. filter pump is operating and primed).

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 pools desired temperature is exceeded by ½°C the pump is stopped until the pool
temperature drops ½°C below the temperature limit setting.

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, WINTER, TROPICAL and SETTINGS.

Summer mode is the normal operating mode for heating the pool.
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 30 minutes manual mode will
time-out and return to the previous operating mode. Note that Manual ON requires an operating filtration
pump in the auxiliary power socket.
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 once a
day 3 minutes after the filtration pump has started.
Tropical mode of operation is for situations where the pool water overheats due to direct heating from the
sun. When the roof is 4°C cooler than the pool temperature, the pump is started (this will most likely occur
at night and therefore requires the filtration to run at night) and will attempt to cool the pool to 1°C above
the temperature limit. Normal heating will occur the next day if the pool drops below the set temperature
limit by 1°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 allow the solar pump to run
whenever there is solar heating available and if the filtration pump is operating. 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 noon, default is 9am which means the
solar pump cannot start before 9am. Now select the END hour from 15 (3pm) till 21 (9pm), default is 19
(7pm) which means the solar pump will stop at 7pm.

SL6E CD INSTALLATION INSTRUCTIONS

CONTROLLER: 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. Do not drill through the box.

SOLAR PUMP: The solar pump plugs into the left side 240Vac socket marked as PUMP. Note
that the solar pump can only operate when the auxiliary power socket uses sufficient power to
trigger the current detection circuit, this detection trigger point can be adjusted (see Installer
Settings).

FILTRATION PUMP: An Ioniser/Chlorinator or equivalent pump timer is to be plugged into the
right hand side 240V socket (auxiliary) located under the POOL & ROOF sensor inputs, the
filtration pump plugs into the Ioniser/Chlorinator pump socket.

TEMPERATURE SENSORS: The pool temperature sensor must be fitted into the suction line of
the filtration 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, in some cases there is some benefit to cable tie
30cm of wire from the pool temperature sensor to the pipe and insulate this section (some
ambient differences can travel up the tinned copper wire and affect the sensor reading).
The roof temperature sensor must be fitted into a small piece of solar collector or equivalent
and attached to the roof. The best location is within an 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.
The sensor plug is to be fitted to the right hand socket marked ROOF. Keep in mind that it is of
the utmost importance to keep the roof temperature sensor cable 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.

All temperature sensor cables must NOT be run parallel to power cables and should never be
cable tied to power cables. All cable run lengths should be less than 50m 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 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.

SL6E CD INSTALLER SETTINGS

PUMP LOAD SETTING: *** IMPORTANT *** The controller will not operate and will display a
‘INSTALLER MUST SET PUMP LOAD’ message. The correct Load setting is required for this
controller to pick up a pump which is failing to prime. After setting the load values test by
starting the solar pump in Manual Mode and ensure that the solar pump will switch off if the
filtration pump fails to provide water.
Filtration Pump Load Automatic Setting: There are 2 methods for setting the load detection of
the filtration pump. For automatic setting ensure the filtration pump is operating and primed.
Then simply hold the UP button then press SELECT, the unit will then display the pump’s load
value and automatically sets the threshold levels and returns to automatic operation, if the
current draw of the filtration pump drops below this level then the solar pump is forced to
switch off.

Advanced Settings: To select the advanced settings, hold the DOWN button then press SELECT.
Filtration Pump Load Manual Settings: If setting the load value, please ensure your filtration

pump is connected to the auxiliary power socket (right hand side) and that the filtration pump
is primed and if it’s a variable speed pump ensure the filtration pump is operating at the
required speed. After releasing the SELECT button the LOAD=xxx value is displayed for 5
seconds, take note of this value. When the LCD screen displays RUN=>xxx it indicates the
minimum load required to allow solar to run, set this value 10% lower than the displayed LOAD
value and press SELECT. The next value to adjust is TRIP> this is the overload value, when the
filtration pump draws too much power (e.g. a variable speed pump operating too fast) then the
solar pump is stopped. *Default is a RUN=>20 and trip >99.
Once the Advanced settings have been adjusted all the above settings will be saved and the unit
will restart. Re-adjust the temperature limit if required.
Adjustable differential: Special note: Adjusting these values to any setting other than the
defaults may adversely affect the performance of this controller. To adjust the differentials hold
the UP button while applying power to the unit. The first item prompted is to set the solar gain
start temperature (RUN° x) this setting allows the pump to start if the roof temperature
exceeds the pool 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 pipe 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.

Factory Test:

To run the factory test, hold the SELECT button when first applying power, the unit will perform
a series of self-diagnostic functions with the pump running.
If there are any faults they will be reported on the display before the unit restarts into normal
operation.

Note: that this will force all settings to a factory default state. Re-enable time-clock if required
also set the Pump Load value, temperature limit and operating mode to their required settings.
