(are pre-set if delivered with a rotary heat exchanger from Hoval)
The DRHX series is equipped with 4 DIP switches for setting e.g. the stepper motor size and maximum motor speed
DIP 1-2: motor size / DIP 3-4: motor rpm
(see table 15.1.1 and 15.1.2).
Required motor rpm is calculated by Hoval. Depends on rotor Ø, pulley Ø, rotor and motor torque, and given rotor
rpm. See table 15.1.3.
