Switch On Heating - Siemens SIPLUS HCS Series Operating Instructions Manual

Functions
9.3 Power output control
The following soft start variants can be configured in order to adapt to the conditions of the
application:
Soft start
Adaptive soft start
With adaptive soft start, the phase angle is adjusted during runtime at the available radiators
so that tripping of the fuse is avoided but the maximum possible start-up speed is reached.
The duration of the soft start thus depends on the radiator used. While with half-wave
control, the soft start only ends with a complete half-wave, phase control is already ended
when the specified setpoint value is reached. If the soft start is not possible, an error
message is generated. The radiator can thus not be operated on the POM.

To control the power outputs, the heating must first be activated. This is done via the cyclic
data.
