Questions and answers
здравствуйте . Аристон клас иккс . дом отапливается тёплыми полами и гистерезис составляет около 15 градусов в отопительном контуре . как добиться гистерезиса 5 градусов так как 15 градусов на полах очень заметно остывают полы .
To achieve a 5-degree hysteresis in the heating circuit for the Ariston CLAS X when using underfloor heating, set the thermoregulation type to "Fixed Flow Temperature" (0 = Fixed Flow) and then set the desired fixed temperature. The system allows temperature settings from 35 °C to 82 °C. Hysteresis control depends on maintaining the temperature range around the setpoint. Specific hysteresis settings are not directly mentioned, so manual adjustment of on/off thresholds around the target temperature may be required.
