Page 4: Operating The System Controller
Operating the system controller By using a thermal solar system you have – with this controller – the possibility to design your own personal solar system. This is guaranteed by various possibilities to adjust parameters and functions. How to change and watch readings, parameters and functions as follows. Illustrations (menu) show and clarifiy the potential selections and give an overview of the menu-driven system controller. - Page 5 illustration 2: Diagram of different menu Example – illustration on menu-driven operation With this example you can see how to fetch current and stored readings within the main menu "READINGS".
- Page 6 2.3 Menu "READINGS" By pushing the OK button within the menu "READINGS" you can fetch the various temperatures of the sensors installed. Moreover, the controller stores minimum and maximum temperature values of the collector, storage tank top and storage tank bottom. These values can be reset just as the solar circulation pump‘s operating hours over a certain period of time or the measured heat quantity (using the function calorimetry).
- Page 7 Apart from this the controller allows for registrating the calorimetry fed into the service water storage basin by an additional volume flow dispenser and the temperatures in the solar forward and backward movement. The volume flow dispenser is a traditional water meter with pulse output point. It is important that the volume flow dispenser resists the higher temperatures within the solar circuit.
- Page 8 3.2.3 Storage tank temperature limitation ("storage temp. limitation") (Appendix 10, illustration C) In order to avoid overheated service water the solar circulation pump P1 will be switched off when reaching a maximum temp. This temperature can be adjusted within a range of 20 to 95°C (within the menu parameter "storage temp.

If an adjustable temp. (menu parameter: "heating system ON") on sensor T3 falls below 3 adjustable time windows (menu parameter: "indexing time 1: ...
- Page 10 C) temperature-linked circulation control and time-linked circulation control The combination of the above functions provides for optimally triggering a circulation pump with an extremly reduced running time. Here the circulation pump is only switched on during a given time window and a parallel temperature undershot. It immediately switches off when a certain temperature is reached.

Page 11: Configuration
T4 of the solar forward movement is used for circulation control. The function of the calorimetry remains the same, however, slight deviations have to be taken into consideration. Note: Within the function calorimetry the microcontroller takes into consideration the physical characteristics of the solar liquids TYFOCOR L (propylenglykol) that are frequently used. -
Page 12: Installation And Operation
Installation and operation Safety instructions The controller has been built for the use at 230 Volt AC at a frequency of 50 Hz [or optional 115 V (±15 %), 60 Hz]. Using this controller for other V and Hz values is not allowed. Please also note that the admissible nominal currents must not be exceeded. - Page 13 5.3 Connecting the controller First of all leave open the wire inputs for the power supply connection and the connecting wires of the sensors and the pump in the casing box. For this purpose there are material draws to be cut out (Illustration 4, Pos.
