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.
Note:
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
