Description

Application

Electronic controller Type TROX UNIVERSAL, for the control of volume flow rate, room pressure or duct pressure, suitable for supply air and extract air and also as an attachment to VAV terminal units
For use in clean rooms in the pharmaceutical and semiconductor industries, operating theatres, intensive care units, and offices with very demanding control and data transparency requirements
Fast and stable control of the supply air and extract air flow rates as well as of room pressure and duct pressure
For extract air led areas such as kitchens
For supply air led areas such as clean rooms, offices and patient rooms in hospitals
Options for the integration of additional volume flows into the room balance
Room pressure and duct pressure control; supply air or extract air flow rate measurement as an option (expansion module)

Controllers can be used individually or combined with other controllers for a complete room solution
System solution for the volume flow control in rooms (room balance)
Central BMS interface, 0 – 10 V voltage signals, digital inputs and outputs, expansion modules for LonWorks, BACnet, Modbus

Special characteristics

Plug and play communication system with automatic controller identification, no component addressing required
Modular system for functional expansion
Connections and status displays on the outside of the controller casing
Project-specific adjustments with adaptable room control panel
Project-specific adjustments can be achieved with configurable special functions, monitoring, and alarm signalling
Permanent function monitoring of the system and the connected sensors
Very simple commissioning with software wizard for configuration changes, maintenance and diagnosis
Centralised configuring and permanent signalling of room settings (room management function)
EasyConnect configuration software enables interactive navigation (with optional BlueCon adapter, wireless controller configuration)
Factory tested and configured with projectspecific parameters

Useful additions

BE-LCD: Room control panel
Static differential pressure transducer for room pressure control
Static differential pressure transducer for duct pressure control, including tube and pressure tap
EasyConnect: Configuration software for the commissioning and diagnosis of TROX UNIVERSAL and EASYLAB systems; BlueCon Bluetooth adapter module available as an option
EasyCon Android app for maintenance and diagnosis as well as for reading and writing certain parameters (only with TROX BlueCon adapter module)

Construction features

Control unit complete with all expansion modules in a plastic casing and attached to the air terminal unit
Controller casing can be opened without tools, except for controllers with with EM-TRF or EMTRF- USV
Expansion modules can be easily retrofitted (automatic recognition, plug and play)
Pin header socket for the connection of expansion modules
Plug sockets for the most important connections on the outside of the casing
Static differential pressure transducer with room air induction to protect the sensor

Materials and surfaces

Casing made of ABS plastic, UL94, V0, lower part in grey (RAL 7037), with blue cover (RAL 5002)

Maintenance

Zero point correction of the static differential pressure transducer should be carried out once per year (recommendation)
If you use expansion module EM-AUTOZERO for automatic zero point correction, no manual correction is required
