Variable volume flow controller for room supply / exhaust air and fume hoods

To achieve stable air conditions in a room while at the same time maintaining the necessary air change rate, the specified direction of flow, if applicable, a certain room pressure and temperature control, all constant and variable exhaust and supply air volume flows must be measured and exchanged between the individual components of the system solution.
For this purpose, the volume flow controllers of the TVLK, TVR, TVRK, TVZ, TVA, TVJ and TVT type are combined with electrical control components based on the TCU-II controller. Information is exchanged between the individual controllers of a room solution using analogue 0-10 V DC signals.

Advantages of analogue 0-10 V communication system

Simple linking of controllers through conventional cabling
A transmitted measurement/value corresponds to a specific physical cable connection
No knowledge of field bus systems required
i.e. no need for system integrators or LON familiarity
Adaptation of controller configuration using a TROX PC configuration software
Use of a Standard-PC / Notebook for commissioning

This analogue technology is particularly suitable for small projects that have few controller components and are not connected to a central building control system.
