- VAV with LABCONTROL
The TROX VAV controller with the LABCONTROL TRA-RS or TRA-RE control component (TCU-II operation type: room supply or exhaust air) can be extended by an external temperature probe. The control of the volume flow balance of the room can thus be enhanced by a temperature control. The volume flow is adjusted based on the recorded temperature without changing the flow direction or the room pressure.
More details
Influencing of volume flow through temperature control in the TCU-II:
The temperature control circuit (comparison of set and actual value) is integrated in the TCU-II and the temperature is controlled by shifting the volume flow.
Volume flow shift by external temperature controller with 0-10 V DC signal:
The temperature control circuit is integrated in an external temperature controller and a signal is connected to the LABCONTROL system to shift the volume flow.
Control of reheater / recooler:
The TCU-II can be operated on a VAV controller with an integrated reheater or recooler. The TCU-II system controls the temperature by shifting the volume flow and via the valve position of the heater or cooler (3-point valve on site).
Additional function:
Switching possibility between heating and cooling via digital switching input
