Electronic Switch Actuator, 4-fold ES/S 4.1.1 Application program „Heat Switch Flush Forced position/1“ Heat The parameter must be set to 1 bit signal or 1 byte signal depending on the thermostat used. Flush This function prevents heating valves from calcifying during the summer. Forced position The forced position is used to move the heating valve to a specified position when certain events occur. Fault signal The Electronic Switch Actuator reports a fault, should telegrams not be received at its switch object within a certain time period. Status This function can be used for visualisation purposes. It displays whether heating or cooling is currently being carried out.
