With PWM control, it is not possible to ensure exact parallel running of 2 or more thermal actuators. 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.
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 list:
Maximum number of actuators in parallel on the RDG100..:
∂ 6 SS..31.. actuators (3-pos)
∂ 4 ST..23.. if used with On/Off control signal
∂ 10 SFA.., SUA.., MVI.., MXI.. On/Off actuators
∂ Parallel operation of SQS35 is not available
Maximum number of actuators in parallel on the RDG110..:
∂ 10 On/Off actuators
Maximum number of actuators in parallel on the RDG160T..:
∂ 10 SS..61.. actuators (DC)
∂ 10 ST..23/63/73.. actuators (DC or On/Off)
