Siemens ACVATIX G B111.9E/KN Series Manual page 6

Commissioning and parameterization
The following operating modes are available:
● Heating / cooling control: The actuator uses two separate setpoints for heating and cool-
ing each with a range 0...100%.
● Position control: The actuator is controlled with a 0...100% position setpoint.
Operating mode "Heating / cooling control"
When using "heating / cooling control" the parameters as listed below are available. Parame-
ter sets for 6-port control ball valves DN 10 and DN 20 can be selected. Details on the char-
acteristic curves of these two valves can be found in the datasheet A6V10564480.
Note that the valve angle [°] moves counter-clockwise, whereas the actuator position [%]
moves clockwise. Therefore valve angle 15° is achieved by an actuator position of 84% etc.
One of the two setpoints (heating or cooling) needs to be "0%" in order for the actuator to be
able to move. Are both setpoints not equal to "0%", the actuator doesn't move until the
setpoint conflict is resolved.

The 6 port control ball valve can
be mounted as shown in the
mounting instruction
A6V10636144 (coil facing
upward) or rotated by 180° (coil
facing downward). The ETS
parameter settings remain the
same, but heating and cooling
change their sides (cf. tables
below).
