  • Page 27 OTC curves settings The purpose of weather compensating control is to reduce the heating water temperature when the outdoor temperature rises (and vice versa). This can effectively reduce overheating or underheating of dwelling space and also increase the efficiency of system operation. From the point of view of energy savings and thermal comfort in living rooms, it is more advantageous to heat the building to the required room temperature with a lower heating water temperature for a longer time than with a higher heating water temperature for a shorter time.
