The controllers adapted to Airbox units offer the best in comfort and safety in the operation, monitoring and servicing of the system. The controllers are manufactured in accordance with VDE guidelines and meet the requirements of the applicable EC directives. Thus together with custom controllers, Rosenberg air handling units provide an optimal device. With this concept, the aim of maximum system well-being and highest comfort with minimum energy use is achieved cost-effectively and safely.
The Rosenberg controller series is suitable for supply air, indoor air or exhaust air temperature control. The controllers are used for transformer control of direct-drive fans, to control standard motors, frequency inverters and EC motors. Only microprocessor-based controllers which allow for high control accuracy are used in ventilation systems for the implementation of the various controller tasks.
TR Basic Controller
The control cabinet TR-Basic is designed for ventilation applications with temperature regulation requirements. The TR-Basic allows operation for fans with external rotor motors, standard motors combined with frequency converter and energy-efficient EC-fans.
Temperature and it´s set-points can precisely controlled with installed room-, outlet- and ambient-temperature sensors. The switch-box for wall mounting is steel-sheet housing with powder coating and a door-sealing made of PU.
The completed control-cabinet is equipped with user terminal in the front-door, which shows text messages and symbols. This local handling allows to read operation conditions and alarms or to modify configuration parameters and set-points.
Airtronic controller series
The latest DDC technology is used in the Airtronic controller series. The Airtronic control unit enables not only standard motors and external rotor motors to be controlled, but also frequency inverter operation as well as control of energy-saving EC fans. The advantages of this technology also include the option of customer-specific adaptation for many applications, making the Airtronic suitable for a highly diverse range of control functions The Airtronic is available in two versions – Airtronic Basic and the more elaborate Airtronic D – which differ according to the maximum number of inputs and outputs and are individually programmed for each air ventilation system.
Functions such as pressure control, flow rate control or fan control according to air quality or CO2 are also possible here. Upon request, the Airtronic control units can be connected to a higher-level BMS via the LON bus or the Modbus.
The control panel can be installed directly into the control cabinet door, or alternatively, be supplied as a remote operating panel. A week program is also integrated for switching the system on and off or for setting different nominal temperatures and ventilation specifications with seven switching times per day. Fault messages, system statuses and internal settings are displayed in plain text.
Both Airtronic and TR controller series have a master switch. This makes it possible to disconnect the entire ventilation system.
