V1
Output 0-10V / PWM
Terminal „ – „ is connected with a common
terminal block for S1-S4 sensors and VFS
sensors and also with earth on the mains side.
The power supply of low-energy pumps
with 0-10V / PWM pumps can be connected to
the corresponding relay (V1 -> R1, R2 -> V2),
since the relays are switched on and off with
the signal.
