The external humidity/temperature sensor SFT-EO can be installed almost anywhere and does not require any additional power supply. If you have coupled the SFT-EO as an indoor sensor to the UNI-EO or FM-EO modules, the values of the radio sensor and the internal sensors are compared and ventilation takes place on the basis of the transmitted
climatic conditions. Coupled with the UNI-EO module as an outdoor sensor, the intelligent control system compares the absolute values of indoor and outdoor climate and adjusts the ventilation accordingly. In addition, automatic summer ventilation can also be implemented: In cooler night-time temperatures, the system ensures a reduction in room temperatures through refreshing cross-ventilation.
