2-step control
2-step control is the simplest form of control. No control value is calculated here. The room thermostat
sends a 1 via the communication object
Switch
if a certain temperature is exceeded and a 0 if the value
drops below a certain temperature. These switch values are implemented by the SA/S.
The room thermostat hysteresis limits can be used for control stability. Use of these limits does not affect
the method of operation of the Switch Actuator.
A room thermostat can use the control algorithm of a PWM control. As the room thermostat sends ON and
OFF telegrams to the SA/S, the actuator operates like a 2-step control.
