With DIP switches inside actuator is
possible to set the following
parameters:
DIP 1
Direction of rotation (direct CW /
inverse CCW)
DIP 2,3 Different temperature ranges
depending on the application
(0°C..100°C, 60°C..85°, 20°C..70°C,

3 Handle for manually controlling the drive, which
also serves for the indication position of the valve
4 Button for adjusting the required temperature.
When adjusting the temperature, the set value
flashes on LCD screen.
