Room control with LABCONTROL

and the analogue communication system with 0-10 V signals


The TCU-II controller (control component TRA) can be used in combination with the TVZ, TVA, TVJ, TVT, TVR and TVRK VAV controllers for controlling variable supply and exhaust air volume flows in rooms. Consequently, the room controllers and fume hood controllers will have the same control speed, which leads to a stable room balance. The volume flow control is independent of channel pressure, i.e. pressure variations do not result in lasting volume variations.

Room control - Characteristics overview

  • Connection of up to 7 actual volume flow values via 0-10 V analogue signals

  • Additional software configurations for consideration of constant volume flows

  • Control of room balance with constant air overstreaming in the selected direction

  • Optional: Control of a definable room pressure, considering the volume flow balance

  • Optional: Control of room temperature, considering the volume flow balance

    Room balance control

     
  • Room balance control with LABCONTROL control components TRA-RS (Supply air) or TRA-RE (Exhaust air)

  • Balance control by means of all connected or configured supply / exhaust volume flows

  • Control of air flow direction based on the room balance and the configured supply/exhaust air flow difference

  • Maintaining the air flow direction as per DIN 1946 Part 7
