Settings on input - E-PROG
1. Connect the external voltage or current source or programmer to
socket REG+E-PROG of the circulator.
2. Selecting the signal:
The programmer (E-PROG) input of the circulator can be matched to
the output signal of the external voltage or current source.
voltage input = U

current input = I 
3. Define the input variable:
Setpoint programmed by external voltage or current
Manipulated (ACTuated) variable for the heater
with an external control pulse
Signal of an external flow sensor
