Function module AZX61.1 offers the following choices for changing control:
· Changeover of acting direction (page 59)
· Sequence control (page 57)
Stem heating element ASZ6.6 prevents the formation of ice on the stem when
medium temperatures drop below 0 °C. It is suited for universal use with valves
having a stem diameter of 10 or 14 mm.
The stem heating element heats up to 85 °C.
This is a PTC element, which means it shows up with a low resistance at
power up – inrush current may reach 8.5 A at low temperatures / high
voltage level
