LVLØ Water Temperature Setpoint Hysteresis Input °C
control EIS5
2 Byte
W
9.001
Floating value (°C). Control hysteresis of the 2-step heating/cooling
controller for water temperature from KNX. Setting rule: Small
hysteresis leads to small fluctuations, but frequent switching.
Large hysteresis leads to big fluctuations, but infrequent switching.
