Application manual for EC-Control
Step 4:
Set parameter set 2
 Control mode: Closed loop
sensor control
 P-factor: 50%
I-factor: 6.25%
 Activate parameter set 2
Fig. 59: Parameter set 2
Step 5:
Set value via RS485/bus
 Set value here: 450 Pa
Night switching
 Source of set values:
RS485/bus
 Activate Save set value to
EEPROM
 Enter required differential
pressure under Set value in
order to control constant air flow
 Set value ≈ Actual value

4.2.2
Analogue setpoint input during air flow control
Optionally, for digital setting of values from Chapter 4.2.1, it is possible to prescribe the set value in a
similar way via the inputs Ain1 U or Ain1 I. Fig. 61 shows, for example, the connection of a
potentiometer for setting of values for the air flow control.
Day / night switchover with two different set values is not possible with an analogue source of set
values. Steps 4 and 5 in the above example thus are omitted from this chapter.
