3-point control with a driving time of 150 s is a factory setting in H1 and H2
control circuits and 0…10V control with a driving time of 15 s is a factory
setting in the DH control circuit. 230V 3-point control can be selected after
the relays have first been reserved for 230V actuator control. After you select
the actuator control mode the controller requests the actuator driving time.
The running time indicates how many seconds go by if the actuator drives
a valve nonstop from a closed position to an open position.
Press the
or
button to set the time. Press
The
character indicates which control mode is being used.
The
button moves you from one regulating circuit to the next.
Directions for entering the
maintenance mode are on page 21
The control mode for each regulating circuit actuator is selected in
actuator selection. Options are either 24 VAC 3-point control or DC
voltage control (0...10V or 2...10V). If relays 1 and 2 are free, they can be
utilized to implement one 230VAC 3-point control. (first choose "230V
Actuator" for the relay control mode. See pages 26 and 27)

Regulating circuit H1 actuator's control output is M1.
Regulating circuit H2 actuator's control output is M2.
Regulating circuit HW actuator's control output is M3.
Attention!
If "230V actuator" has been
selected for relays 1 and 2, one 230VAC 3-
point controlled actuator can be connected to
the regulator for any regulating circuit (H1, H2
or HW). Selection of relay control modes is
shown on pages 26 and 27.
