[. . . ] SUN COMPENSATOR - SOLAR SENSOR PRODUCT DATA SAF25 APPLICATION The SAF25 Sun Compensator ­ Solar Sensor is an active sensor with standard output signal (0. . . 10 V). The heating consumption of a room depends largely on the outside temperature. [. . . ] The SAF25 contains two temperature sensors to register solar radiation (see Fig. The temperature sensor (1) measures the ambient temperature and the solar sensor (2) measures the radiation from the sun. The difference between the two temperatures represents the additional heating of the building by the sun.
