MODEL SL8 RR - D g tal Solar Controller
DESCRIPTION:
The SL8 RR is a swimming pool controller that heats a swimming pool by the use of solar panels.
If solar gain is available the solar system will heat the pool to the solar limit (sol limit).
Solar has a time lockout that prevents heating outside of the time set (default 09:00 – 18:00).
CONTROLLER MOUNTING:
The controller enclosure must be firmly attached to a nearby solid fixture by either the two mounting
lugs or direct attachment though the controller. If mounting through the controller ensure the power
cord is disconnected from the mains supply then remove the enclosure front cover by turning the four
corner locks so each arrow points to the ‘O marked on the front cover. Insert two mounting screws
diagonally through the oval holes in the enclosure, refit front cover and turn the four corner locks to the
‘I position.
The power cable is 1.8m long and should be plugged directly into a general power outlet, not into an
extension lead.
CIRCULATING PUMP:
The solar circulating pump plugs into the right hand 240Vac socket marked as SOLAR PUMP. The left
hand 240Vac socket marked as AUXILIARY will provide continuous power, the AUX ON. LED will also be
lit.
The maximum combined current is 10 AMPS 2400W.
TEMPERATURE SENSORS:
The pool sensor must be fitted into the suction line of the solar boost pump, preferably in a position out
of direct sunlight. For retro-fit systems the pool sensor must be fitted in the suction line before the take
off Tee fitting for the solar boost pump. 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.
This unit has been designed to eliminate the need to run a temperature sensor cable from the solar
controller to the roof, this is replaced by a Solar Powered roof temperature transmitter that only
transmits when in direct sunlight, and a receiver that calculates the roof and pool temperature turning
on the solar pump when required.
As the unit operates in a UHF radio band, reflections and moving objects can cause a transmission to be
corrupted with a subsequent indication “ROOF SIGNAL NOT RECEIVED” on the display. Up to 10
transmissions can be missed (and last valid reading is kept for 10 minutes) before pump action will
occur and the solar pump will turn off. If this occurs, and if the solar conditions are still favorable, the
solar pump will not turn on again and resume normal operation unless it has received a valid
transmission.
The remote roof transceiver obtains its operating power from a solar panel, it will not operate if there is
no sun or if there is significant cloud cover. Obviously solar heating would not occur in such conditions.
Due to the possibility of reception ghosting and electrical interference the Transmitter may be required
to be moved to an alternative position, this may be as little as two meters and keep in mind that the
roof sensor cable may be extended 20 meters if required. The main controller should be mounted away
from other electrical appliances as far as possible to reduce the chance of interference. If the unit is to
be installed in a metal shed there may be reception issues and the controller may need to be optioned
with a remote antenna or moved outside.

SETTINGS MENU:
To enter the SETTINGS MENU push either the up or down buttons and the following will be
displayed;
SETTINGS MENU
1) MANUAL MODE
Use Up/Down buttons to scroll to the option you wish to change, selectable options will be
flashing on the display.
Press the Enter button to accept the currently selected menu item.
All menu items are shown below;
SETTINGS MENU
1) MANUAL MODE
2) TEMPERATURE
3) MODE
4) SET CLOCK
5) SAVE & EXIT
1) MANUAL MODE
MANUAL PUMP MODE
UP=ON DOWN=OFF
MANUAL MODE allows you to manually set the pump to ‘on by pressing the Up button or ‘off by
pressing the Down button.
Pressing Enter will return you to the SETTINGS MENU. You can also keep pressing Enter to
toggle the pump from ‘on to ‘off and vice versa.
MANUAL MODE will time out, after 24 hours the SL8 will return to normal operation.
2) TEMPERATURE
TEMPERATURE
SOL LIMIT XX.X°
When you enter the TEMPERATURE menu you may change the solar heater temperature limit
setting (SOL LIMIT) by pressing the Up/Down buttons, if no change is required simply push
Enter.
Factory default is for SOL LIMIT is 30°C.
3) MODE
MODE
SUMMER MODE/AUTO WINTER MODE/TROPICAL MODE
You can use Up/Down to change the selected option, Enter to accept.
SUMMER MODE is the normal operation of heating the swimming pool.
TROPICAL MODE is selected if you wish to cool the swimming pool, the solar pump will run if
the roof temperature is colder than the pool until SOL LIMIT is obtained; note that this is most
likely to occur at night.
WINTER MODE, when selected you will be prompted to select the start month of winter and the
start month of summer, this assists in the systems off-season maintenance and save energy as
solar gain may be available but swimming temperature cannot be achieved.
A three minute flush of the solar matting occurs between 10:00 and 16:00 providing the roof
temperature is equal or greater than the pool, but if that condition does not occur a solar system flush
will be forced to occur at 16:00.
4) SET CLOCK
TIME 17:00:PM
DATE 08/09/2010
When you enter the CLOCK menu you will be prompted to change the DATE setting first, adjust by
pressing the Up/Down buttons, to accept the setting press the Enter button.
Repeat for Month, Year, Hour & minutes.
Note: time is in 24 hour format, there is also an AM/PM displayed to avoid clock setting errors, when
setting the clock, seconds is set to 00 (zero)
5) SAVE & EXIT
When this menu is selected, push Enter to save ALL settings, the unit will return to normal operation
automatically.
Note: If any of the menu items are left unattended for 3-4 mins the menu will time out and

If you Enter is pressed for a second time within a 3 second period, the display will indicate you have
entered Manual mode, operation is the same as manual mode in the menu with the only difference
being the timeout value is 4 Hours.
NOTES:
1. If a sensor fault is detected the SL8 will display which sensor and what the fault is.
2. Should power be interrupted for any reason, the SL8 will resume normal operation when power is
restored, all information will have been kept.
3. Temperature sensors used with this unit are Digital and are accurate to 0.5 Deg. 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, incorrect polarity will be displayed.
5. Solar start and end times may be changed by holding the Up button while power is applied.
