1. Product description
Your solar controller is a microprocessor-based controller, for control of solar energy systems with one collec-
tor array and one storage reservoir. The pump is controlled so as to optimise the heat energy obtained from
the solar collector array, according to the solar irradiation and the temperatures which arise in the solar energy
system. With the heat energy thus obtained, one storage reservoir can be loaded, e.g. a domestic water
storage tank or a swimming pool.

3. Safety instructions
DANG R
Danger of electrocution!
The controller is to be assembled, electrically installed, commissioned, inspected and repaired by
trained, competent and authorised persons (qualified electricians as per DIN VDE 1000-10 and
BGV A3) only!
Observe all applicable guidelines and regulations of the local electricity supplier!
Before beginning installation or repair work on electrical equipment, always ensure complete
disconnection from the mains and secure against reactivation!
Do not work on live parts!
The controller may only be installed and operated in:
dry environments which are not potentially explosive
closed rooms
rooms with a temperature between 0 °C and + 50 °C
Technical data
Page 5
4. Transport and storage
Thoroughly check whether the packaging or the controller shows any sign of damage.
Transport the controller in the original packaging only.
If the controller falls, even from a low height, it may get damaged.
Prevent impact and extreme temperatures (below 0 °C or above + 50 °C) during transport and storage.
The controller may only be stored in its original packaging and in a dry environment.
5. Installing and connecting the controller
5.1. Proceed as follows – step by step
1. Check whether you wish to use additional functions (see 5.2. Possible additional functions and 10.
Setting the additional functions [the individual additional functions are explained here]).
2. Check whether the desired additional functions can be realised, i.e. whether there are free sensors and
relays for the functions (see 5.3. Relay connector assignment and 5.4. Sensor connector assignment).
3. Install the controller at a suitable location and realise the electrical connections (see 5.6. Installing the
controller and 5. . Electrical connections).
4. Install the required sensors (see 5.8. Installing the collector sensor and storage reservoir sensor).
5. Connect the required sensors to the controller and assign the relays according to your requirements
(see 5.3. Relay connector assignment and 5.4. Sensor connector assignment).
6. Switch on the controller by pressing and holding the button for at least 5 seconds.
7. amiliarise yourself with the controller’s menu navigation (see 6.1. Front view of the controller with
buttons and display and the detailed description in the operating manual).
8. Configure any additional functions (see 10. Setting the additional functions).
9. Record your settings in the respective sections of this commissioning manual under “Selection”
(10. Setting the additional functions).

1. Choose a suitable installation location.
2. Remove the collector’s terminal cover.
3. Mark and drill (Ø 6 mm) the central upper fastening hole. Insert the provided rawlplug and a screw.
4. Hang the controller on the screw and align it.
5. Mark the lower fastening holes (140 mm between holes). Remove the controller once more.
6. Drill the two lower holes (Ø 6 mm).
7. Insert rawlplugs and hang up the controller once more.
8. Screw the controller firmly in place at the two fastening holes.
Risk of injury!
Do not use the controller as a drilling template!
DANG R

5.7. lectrical connections
Danger of electrocution!
Every time the terminal cover is opened, the controller is to be disconnected from the power
supply beforehand!
Ensure that it cannot be reactivated!
The type of current (alternating current) and the voltage must match the specifications in the
connection diagram.
Connect the controller as shown in the connection diagram.

Electrical connections are to be realised with screw terminals (single wire / fine wire, max. 1.5 mm²).
The mains supply’s protective earth connector is to be connected to the 5-pole terminal block ( ).
Protective earth connection of loads (pumps etc.) is to be realised at the 5-pole terminal block provided for this
purpose. In so doing, it must be ensured that the mains supply’s protective earth connector is also connected
to this terminal block. Each terminal may only be connected to one connecting wire.
Adequate strain relief must be ensured!
Only use the Pt1000 temperature sensors approved for use with the controller. All cables which carry low
voltage (e.g. sensor cables) are to be routed in such a way that they are kept separate from cables which
carry mains voltage.
The polarity of the sensor cables is arbitrary.
!
Note!
Safety extra-low voltage is not to be connected with the relays on the high-voltage side (R1 to R2).
After the electrical connection work, replace the terminal cover.
5.8. Installing the collector sensor and storage reservoir sensor
!
Note!
Do not route sensor cables together with cables which carry more than 50 V (low voltage)!
Shield sensor cables sufficiently.
Thermally insulate sensors and piping.
Installing the collector sensor:
Insert the collector sensor into the provided opening on the collector array and fasten it in place (refer to the
installation instructions from the collector manufacturer).
Installing the storage reservoir sensor:
Insert the storage reservoir sensor into the provided opening at the storage reservoir and fasten it in place
(refer to the installation instructions from the storage reservoir manufacturer).
Sensor cables can be extended to a maximum length of 100 m.
!
Note!
As temperatures of up to + 90 °C arise in the domestic water storage reservoir, a thermal hot water
mixer must be installed (German Heating Installation Regulation HeizAnlV § 8 para. 2)!
In order to protect the storage reservoir from high temperatures, or to limit loading to the storage
reservoir’s maximum temperature, the collector safety function (KS ) can be set to “no” on the
operating level E3-6 / 2.
5.9. Dismantling and disposal
DANG R
Danger of electrocution!
Disconnect the controller from the power supply before dismantling!
Ensure that it cannot be reactivated!
To dismantle the controller, follow the installation instructions in reverse order.
Disposal must comply with the German Electrical and Electronic Equipment Act (ElektroG), which
governs the sale, return and environmentally sound disposal of electrical and electronic equip-
ment.

switch-on temperature difference TDE the speed-controlled solar
pump R1 is switched on and the storage reservoir is loaded.

If the pumps have been deactivated for a long time, there is a risk that they will block when reactivated, due
to accumulated dirt or limescale. In order to prevent such blockages, the pumps are switched on for 10 sec-
onds at a certain time each day.

Note!
Mark the additional functions which you have selected, as follows:
.
10.1. Additional function: low flow
In order to optimise the loading process, loading of the selected storage reservoir is only enabled once the
collector temperature TCS (which is set here) is reached. When selecting this function, it is important to ensure
that the loading pumps’ minimum speeds are set to values below 100%, i.e. that speed control is possible.

To navigate to the submenu for “manual adjustment” of relays, press or repeatedly until “REL”
appears in the display. Call up the “relay test” sublevel by pressing the button. This causes all outputs
(relays) to be switched off!

Once the button has been pressed to select the relay, the symbol appears. The relay’s switching
state can now be changed by pressing the buttons and . The relay’s switching state thus set will
then remain in effect until the relay test level is abandoned.
14. Faults and troubleshooting
If your controller ever ceases to function properly, please check the following points:
1. Power supply:
If anything appears in the display, there is no problem with the power supply. If nothing appears in the display,
please check the mains voltage and the device fuse.
2. Sensors and sensor cables:
If realistic temperatures are shown in the display (normal display and information level), there is no problem
with the sensors or sensor cables. “H °C” appears in the event of a sensor interrupt and “L °C” in the event of
a sensor short circuit.
If the displayed temperatures are unrealistic, you can use an ohmmeter to check that the resistance values
correspond to those in the following table:
