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
● 10 SFA.., SUA.., MVI.., MXI.. On/Off actuators
● Parallel operation of SAS31 not available
Max. number of actuators in parallel on RDG200KN (AC 24 V):
● 6 SS..81.. actuators (3-position)
● 4 ST..73.. if used with On/Off control signal
● 2 SFA71.. On/Off actuators
● Parallel operation of SAS81 not available
Max. number of actuators in parallel on RDG260KN (AC 24 V):
● 10 SS..61.. actuators (DC)
● 10 ST..23/63/73.. actuators (DC or On/Off)
● 10 SFA.., SUA.., MVI.., MXI.. On/Off actuators
● 10 SAS61.. actuators (DC)
● 10 GDB161.9E
