  • Page 13: Control Modes

    SAUTER flexotron®400 - RDT410 Control modes Control modes The RDT410 can be configured to any one of the following control modes. 1. Supply air temperature control. The supply air temperature is kept at the setpoint value by controlling the output signals on AO1 and AO2.
  • Page 14 SAUTER flexotron®400 - RDT410 Control modes For control mode 3, “Cascade connected room / extract air temperature control” you also need 2 sensors, “Supply air sensor” on AI1 and “Room sensor”, which are placed in the room or in the extract air on AI2.
  • Page 15 SAUTER flexotron®400 - RDT410 Control modes External setpoint It is possible to use an external Ni1000 setpoint device. The setpoint device is connected between terminal 10 SPI and the reference for the analogue inputs, . For more information on configuration and setpoint reading, see chapters 7 and 10.
  • Page 16 SAUTER flexotron®400 - RDT410 Control modes Shutdown mode (Only if frost protection sensor has been configured) Whenever the running mode switches to ”Off”, (normal shut-down or frost protection is activated) the controller will go into ”Shutdown mode”. The shutdown controller will control the output that is tied to the frost protection function to maintain a constant 25°C at the frost protection sensor.
