3.2.5 Frost protection
This function can be switched on/off in the “Basic settings” menu, point 11 and the start temperature can be adjusted in point 13. Furthermore, a frost protection sensor can be selected
For systems driven without or with very low amounts of antifreeze, the pipes and the collector have to be protected from freezing. For this purpose, the selected frost protection sensor measures the temperature at an exposed place, e.g. blank pipes before the collector. If the measured value is lower than the start temperature, the solar pump is activated until the adjusted frost protection start temperature +5K is reached.The minimum runtime of
the pump is 5 minutes.
For security reasons the function is deactivated if the temperature of the priority storage falls below 5ºC.
3.2.6 Energyproductivity measurement
For the purposes of energy productivity measurement (solar gain), a sensor on the collector return line and a flow meter are required.The yield value is calculated from the values of the temperature difference between the collector and collector return line and the value measured by the flow meter. This function is switched on and off in the “Basic settings” menu.

3.2.7 Operatinghoursmeter
So long as the storage tank is charged by a pump, the operating hours meter records for each separate pump. The number of operating hours can be read in menu “info” and for each pump separately reset to 0.
