9.3 Power output control
Defined soft start
The soft start occurs with a fixed number of half-waves. While with phase angle control, this
number is always constant (depending on the choice of version), for phase angle control, the
soft start is already ended on reaching the setpoint.
The following versions can be configured in order to adapt to the conditions of the
application:
Soft start version
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 angle 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.

Description
1
Time-optimized version of the soft start, enabling the heating elements to be
warmed up very quickly. The time required for one channel is about 500 ms for
POM4220 and 100 ms for POM4320.
2
Slower version of the soft start that ensures the heating element is not unduly
loaded. The time required for one channel is about two seconds.
