*) With PWM control, it is not possible to ensure exact parallel running of
more than one thermal actuator.
If several fan-coil systems are controlled by the same room thermostat, preference
should be given to motorized actuators with On/Off or 3-position control.
Note:
For the parallel operation of the actuators, refer to information in the data sheets of
the selected actuators and to this list, depending on which value is lower:
Maximum number of actuators in parallel on the RDG100KN
• max 6 SS…31.. actuators (3-pos)
• max 4 ST…23.. if used with On/Off control signal
• max 10 SFA.., SUA.., MVI.., MXI.. On/Off actuators
• Parallel operation of SQS35 is NOT possible
Maximum number of actuators in parallel on the RDG160KN
• max 10 SS…61.. actuators (DC)
• max 10 ST..23/63/73... actuators (DC or On/Off)
• max 10 SFA.., SUA.., MVI.., MXI … On/Off actuators
• max 10 SQS65 actuators (DC)
