With PWM control, it is not possible to ensure exact parallel running of more than one thermal actuator. If several
actuators are controlled by the same room thermostat, preference should be given to motorized actuators with
On/Off or 3-position control
For more information about parallel operation and the maximum number of actuators that can
be used, refer to the Data Sheets of the selected type of actuator and the following listing:
Maximum number of actuators in parallel operation with RDG400KN and RDG405KN:
