2. Functional specifications
2.1 Working action
The Slimline is a complete SunDisc®Pump Controller for heating swimming pools by means of
solar energy. The controller measures the swimming pool temperature and the collector
temperature. As soon as the collector temperature is suitable to heat the swimming the
controller starts the SunDisc®Pump to circulate the heated water.
As the pump is started on bases of the delta temperature (delta-T) than it will be active for at
least 3 minutes.
The controller checks also every 24 hours, from the time that the power supply has been
connected, if the pump has been active in this period of 24 hours.
Is this not the case than the pump will be activated to prevent long water stagnation in the
ducts. The duration of the pump circulation can be adjusted in the internal parameter P50.
If one of the temperature sensors is defective than this is been indicated by an error code in the
display.
Optionally a SunDisc®Remote Display can by connected to the controller. On this Remote
Display the pool temperature is shown and the status of the SunDisc®pump.
2.2 Installation.
On the connection diagram for the Slimline specifies how the power supply, the pump, the
sensors and an optional Remote Display have to be connected.
Make sure that the controller can be disconnected from the power supply, by a maintenance
switch or by connecting the power supply of the controller by a cable with a plug for an wall
outlet.
Use ferrules preferably not soldered on the cable ends. Think of the right wire diameters.
Connect the cable shielding of cables only on one side to the PE (= earth)!
For the shielding of the temperature sensors use the PE terminal between terminals 2 and 3.
The RS485-network is shielded on terminal PE between terminals 4 and 7. The pump cable and
power supply cable shield is connected on terminal PE between terminal P2 and terminal N.
The power supply should be sufficient fused for the pump and controller.
If the shield of a cable is laid on both sides to the earth, huge currents can be inducted which
can cause damage. If indeed the shield on both sides of the cable is connected to earth, a
compensation wire between these two ground points must be made with a minimum wire
diameter of 4mm2.
Never place the sensor and network cables in the same cable duct as the heavy current cables.
This causes failures and may eventually damage the controller.

3. Operation
As long as the power supply is connected to the controller the LED power on controller is lit.
After activating the controller it will show, within several seconds, the measured pool
temperature (Sensor-1) in the display.
3.1 Control elements.
The Slimline can be operated via 5 buttons on the front panel. These buttons are:
ON/OFF -To switch the controller on/off, indicated by the On LED.
UP -To increase the set value / readout the collector temperature.
DOWN -To decrease the set value / readout the delta temperature.
SETP. -To view / change the set value / reset the alarm.
PUMP - Pomp-mode selection button.
3.2 Switching the controller on/off.
The controller is switched on/off by pressing the ON/OFF button. When the controller is on
the ‘On’ LED lights up at the right-hand top of the display and the measured pool
temperature (Sensor-1) appears in the display.
3.3 Viewing the temperatures.
The pool temperature of sensor-1 is normally shown in the display.
Sun collector temperature:
Press the UP button. The measured temperature of sensor-2 (sun collector
temperature) will now be shown on the display for approximately 1 minute.
Delta temperature:
By pressing the DOWN button the delta temperature (= temperature difference
between the sun collector temperature and the pool temperature) appears in the
display for approximately 1 minute.
By pressing any key the pool temperature of sensor-1 (= normal display mode) will reappear
immediately in the display.
3.4 Viewing and/or changing the setpoint (= maximum set pool temperature).
When the SETP. button is pressed, the setpoint (maximum set pool temperature) is shown in
the display. The ‘set’ LED will also starting flashing.
Release the SETP. button.
The setpoint can now be changed by now pressing the SETP. button simultaneously with the
UP or DOWN button. A few seconds after the SETP. has been released, the setpoint
disappears and the measured temperature is visible again. The new setting will be saved.
The standard setpoint setting is 32C and is adjustable between 0C to 32C. The limits can
be modified by the dealer by means of internal parameters.

3.5 Operating the pump control.
The PUMP button is used for switching between pump modi.
The following pump modes are possible;
- Pump manually OFF, the LED flashes and the pump is switched off continuously.
- Pump manually ON, the LED is on and the pump is switched on continuously.
- Pump in automatic mode, the LED is on and the pump is switched on if there is a
positieve yield or during rinsing (if the pump has not been running for 24 hours).
The pump set mode is stored.
After power failure to the controller is always the last chosen mode pump.
After switching on the controller via the ON/OFF button to the controller in manual mode off.

4. Programming internal settings
In addition to the setpoint adjustment, there are also a number of internal settings such as the
differences, sensor offsets, setpoint range and pump settings.
These internal parameters may only be changed by SunDisc®or the SunDisc®Dealer in order to
guarantee the proper operation of the system. Only a few of these settings can be changed by the
user.
Holding down the DOWN button longer than 10 seconds will give access to the 'internal programming
menu'. For access to anything other than the user parameters, the access code first has to be entered.
This can be done by pressing the PUMP button. A digit appears at the position that can be changed,
the other positions contain a hyphen. Enter the desired digit via the UP and DOWN buttons. After the
SETP. button has been pressed, the next digit can be entered. The parameter menu will be accessible
when all digits have been correctly entered. Once entered correctly, the code will remain active for five
minutes after leaving the parameter menu.
Once in the parameter menu, three horizontal segments will flash in the left-hand display and the
parameter number will appear behind these. The desired parameter can now be selected (see
parameter table) via the UP and DOWN buttons.
When the desired parameter has been selected, the parameter value can be read by pressing the
SETP. button. To change the value, the SETP. button must be pressed simultaneously with the UP
and/or DOWN button.
If, after 20 seconds, no button is pressed, the Sundisc®Slimline will return to its normal operating
mode.

5. Operating principle
6. Sensor calibration
The temperature sensors for the pool and collector are calibrated ex factory and the deviation is
specified on a label on each individual temperature sensor. To put to use, both sensor deviations only
have to be set on the regulator by the Dealer if this has not already been done by SunDisc®.
The offset for the collector sensor (T1) must be corrected under parameter 01.
The offset for the collector sensor (T2) must be corrected under parameter 02.
If, for example, the label on the pool temperature sensor specifies the value 0.9, then this means that
this temperature indicates 0.9C too low in relation to the gauge temperature of 22C. The value that
then has to be entered under parameter 01 is 0.9 (positive). If the value on the label reads +2.0, then
the value of -2.0 has to be entered under the relevant parameter.
Example: If a temperature sensor has to be replaced by a new sensor then the Dealer or SunDisc®
employee has to enter the specified deviation (e.g. -0.5C) as a negative value
(-(-0.5C))=+0.5C in the corresponding offset temperature sensor parameter (02 for the
collector and 01 for the pool sensor), irrespective of the value that was already there.
N.B. 90% of the sensor calibrations are performed by SunDisc®. Dealers should only perform
calibrations if they have regulators in stock and a different cable length supplied by SunDisc®.
