4. PWM [81] [82]
Connection: Clamp 81: PWM +
Clamp 82: PWM –
The control module offers the option of using
an external speed target value specification
with 2 different PWM models.
The following setting can be made here on the key (1):
PWM standard LED (2) flashing
In PWM standard operation, the pump is controlled
via an external PWM signal.
PWM multitherm, LED (3) flashing
In PWM multitherm operation, the pump is controlled
via an external multitherm signal.
