With PWM control, exact parallel run of 2 or more thermal actuators is not
possible . If several fan coil units are controlled by the same room thermostat,
motorized actuators with On/Off or 3-position control are preferred.
For more information about parallel operation and the max. number of actuators
that can be used, refer to the data sheets of the selected actuator type and the
following list:
Max. number of actuators in parallel on RDG200KN (AC 230 V):
● 6 SS..31.. actuators (3-position)
● 4 ST..23.. if used with On/Off control signal
3-positon actuators
AC 24 V
DC 0…10 V actuators
