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.
