The water temperature can be set externally. A 2 or 3-way motor-driven valve with an operating voltage of 230 V (not included in delivery) is used for controlling the heating process. It is also possible to control a solar circulation pump (230 V). In the case of Solar-11, both the water temperature and the absorber temperature can be read off from the display. The water and absorber temperatures are continuously monitored using two separate temperature sensors. If the absorber is warmer than the swimming pool water by an adjustable temperature difference, a motor-driven valve is activated so that the water is pumped through the absorber so that it can be warmed there by solar radiation. If the absorber cools down so strongly due to the water flowing through it that appreciable warming of the water is no longer taking place, the motor-driven valve blocks the water feed until it can be warmed by solar energy once again. This alternating switching on and off of the absorber is repeated for as long as required until the swimming pool reaches the limit temperature which has been set. The absorber remains blocked off above this temperature. If this alternating process is to be prevented, the solar sensor must be installed on the roof next to the absorber so that it is continuously exposed to solar radiation. Installation of the sensor on the roof does, however, decrease the control accuracy of the control system, and we recommend professional installation on the absorber for this reason. If the differential temperature between the solar absorb and the swimming pool water is adjusted, the equipment can be optimally matched to local conditions (e.g. efficiency and heat capacity of the absorber, volume of the swimming pool, pump capacities etc). (See page 4). Install solar sensor on return feed or next to collector Mains supply 230V 50 Hz 2-way actuating drive solar differential regulator Filter equipment Water temperature sensor Operating Manual Solar-11 and Solar-1 Page 3 (6) Installation The controller must be mounted protected against moisture in accordance with its protection class. The device must be powered via a multi-pole main switch with a contact opening width of at least 3mm and a residual current circuit breaker with IFN 30mA . The device must be isolated before opening the housing. The water temperature sensor is fitted to the filter pump suction or pressure line using the R½" immersed sleeve available as an accessory, where it detects the current temperature of the swimming pool water. The black anodised solar sensor (aluminium) is attached to the absorber output side and measures the temperature of the water warmed by solar radiation in the absorber. When installing this sensor, please ensure that there is good heat contact with the absorber or with the returning, heated water. On no account may it be in contact with cold swimming pool water on the input side. The temperature at the temperature sensor installation site may not exceed 80 °C. Electrical power supply: Electrical power supply connections, in addition to alignment and service work, may only be carried out by approved electricians. The attached circuit diagrams and all applicable safety regulations must be observed. - Solar differential regulator for 230 V motor-driven valve Mains supply 230V/50Hz Solar sensor Water temperature sensor - Actuating drive or The functions "open" and "closed" can be swapped by swapping the cables on terminals 2 and 6. A circulation pump is connected to terminal U1. Circulating pump Operating Manual Solar-11 and Solar-1 Page 4 (6) If actuating drives from other manufacturers are used, please observe the wiring diagram supplied with the actuating drive! If water is to be pumped through the absorber, terminal U1 is under power and the indicator lamp will illuminate. Otherwise, terminal U2 is under power. The loading on the output terminals may not exceed 4A (especially important if the motor-valve and circulation pump are in parallel). Only the original temperature sensors as supplied may be used. The sensor cables may not be routed together with mains cables. If required, it is possible to extend the sensor cables up to 25 m in length if screened cables are used (minimum 0.34 mm2). The sensor system and the control unit are matched to one another and may not be replaced. Sensor balance After individual sensor systems have been replaced, balancing may be carried out again at the controller since the inevitable tolerances in the sensor electrical properties would otherwise lead to inadmissibly large measurement errors. This balancing may only be carried out when the controller is switched on and the housing has been opened. Since some components in the controller carry life-threatening mains voltage (230 V!) this work may only be carried out by a qualified electrician! An service terminal is necessary to measure the signal voltages in the controller, and a suitable thermometer is also required for determining the relevant water and absorber temperatures. Maintenance and service work may only be carried out by an authorised electrician. Connecting plug for the service terminal.

The following display is visible in the service terminal:.

The solar heating can be switched on manually using the key on the service terminal, and off again using the key. + The solar differential regulator must be switched off at the mains switch before removing the service terminal plug.
