Safety and guarantee Please observe the following instructions during installation and operation of Rosenberg system regulators: Assembly and electrical work only by trained and authorised technical staff and according to the current relevant and local regulations or standards. The currently applicable operating instructions must be observed! We reserve the right to make alterations to construction and design in the direction of technical progress. Quality management system DIN EN ISO 9001 Rosenberg products are produced with the most up-todate manufacturing methods. Consistent inspection of...

Rosenberg system regulation Rosenberg is the contact for project management, system identification, delivery, setup and agreement of technical regulation installations. These installations embody the concept of "everything from one source" and make us good at solving problems in ventilation technology. In this way any interface problems in the planning process are avoided by planning the technical ventilation installation in-house and in the layout of the tailored technical regulation installation by close contact with our project team. With the use and combination of high-quality components,...

Airtronic Basic ■ MSD / RTE / RTD ■ Airtronic Basic ■ Airtronic D Layout of the catalogue details: The catalogue is divided into four sections. In the first section, the three control concepts are each presented on three double pages. In the second section, with the help of ten block circuit diagrams the design of a technical ventilation installation is presented in the form of standardised symbols as described in DIN EN 12792 Part 1. An explanation of the symbols used can be found in the appendix. The third section is dedicated to accessories. The components supplied by Rosenberg are described here....

Housing dimensions Switch box and housing dimensions Plastic-coated grey steel housing (RAL 7032) with protection type IP 54. The measurements given in the following table apply only to the combinations of control devices described in the catalogue. Depending on customer-specific design of the devices, the housing dimensions/weights can be varied from those given. Information on devices in the AD.. DF manufacturer's series With Airtronic D devices for frequency change drive, the housing dimensions/weights given for the required frequency converters are not taken into account. The size and weight...

Description of the controller/TR devices The Rosenberg Compact controller series MSD...TR (for standard motors) or RTE/D...TR (for external rotor motors) is especially suitable for the control of room temperature or inlet air temperature in technical ventilation systems. The control circuit board contained in the compact un-troller series is to set the room or inlet air temperature in conjunction with a room sensor and intake air sensor. The control takes place on a water heat register by the continuous control of the three-way mixing valve. If on the other hand an electric heat register is used,...

Cascade control Control functions ■ Control of the heating pump by use of a hot water unit ■ Control of the cooling pump by use of a cold water unit ■ Control of inlet and outlet air dampers ■ Manual continuous control of the mixed air damper ■ Inlet/outlet air dampers shut on frost alarm ■ Three-way valve on frost alarm to maximum flow (heating pump on/fan off) ■ Inlet air temperature control ■ Room/inlet air or outlet air/intake air cascade control ■ Minimal limiting of the inlet air temperature ■ Heating sequence: hot water heat register or electric air heater (up to 4 levels) ■ Cooling sequence:...

Airtronic Basic Description of the controllers / Airtronic Basic Airtronic Basic controllers have been specially designed for the control of Rosenberg housed instruments and they represent optimum comfort and safety in operation, monitoring and service of the system. The most up-to-date DDC technology is used. Amongst the advantages of this technology, the option of customer-specific adjustment should be emphasised for very many applications. Complete operation is carried out remotely via a remote control display on which all fault reports and conditions of the service are shown in writing. The...

Controller description / Airtronic D Airtronic D control devices represent the highest level of development of the Airtronic series and are based on the Airtronic Basic. In addition, operation is also possible with frequency converters as drive units for the fans, pressure, humidity and flow volume control and air quality measurement. Control may also be linked to building control systems via a visualisation program. Remote interrogation and intervention are possible over a modem. Airtronic D control devices cover the entire spectrum of control and drive control of air and air conditioning technology....
