Table 47: Two-step control (switching)
The 2-step control is the easiest way of controlling. The controller switches the control value only on
and off.
The controller switches the control value (for example at heating) on, when the measured
temperature falls below a certain temperature. By exceeding a certain temperature, the control
value will be switched off again. The points for switching on and off depend to the current adjusted
setpoint and the adjusted hysteresis.
The 2-step control is used in situations, where the control value can only have two conditions and the
controlled temperature can alternate a bit more.
