BS2-VR-01 volume flow and pressure controller module

The BS2-VR-01 volume flow and pressure controller module of the BS2 bus system is an important component of a ventilation and air conditioning system control in a building. The volume flow and pressure controller module enables the connection of up to four electronic volume flow and/or pressure controllers manufactured by Wildeboer. The module can be used to optimise the energy efficiency of a ventilation and air-conditioning system noticeable.

For this purpose, the supply air and extract air volume flows of connected controllers can be specified time-controlled via the parameterisable calendar control, depending on the use of the building. Furthermore, a demand-oriented specification can be made via sequence controls by integrating presence detectors and CO² switches. Window contacts can also be integrated in order to carry out forced control of the connected controllers. For example, to close the controllers as soon as a window is opened. The resulting reduction in the fresh air volume flow of the system leads to a clear reduction in the energy required for the entire ventilation system and reduces costs.

Monitoring functions enable the graphical analysis of the ventilation conditions of the system. An adjustment can be made at any time from a central location.
 

Properties:

• The modules store data permanently, even in the event of a power failure.
• With Euro plug and 1.5 m connection cable for direct connection to an on-site 230 V AC socket. Alternatively, the Euro plug on the module may be removed for permanent connection.
• LEDs for displaying the operating data.
• Real-time clock with leap year correction and summer/winter time changeover.
• Operating voltage 24 V DC for the connected controllers from the module.
• Connected VRE1/VKE1 controllers are automatically fully recognised by the module and their factory-set customer-specific parameters as well as type and size are read out.
• Connected MP-bus-capable controllers (manufactured by Wildeboer) are automatically recognised by the module and their factory-preset parameters are read out. Type and size must be selected manually according to the respective controller.
• Communication between module and connected controllers via RS485 or MP-Bus.
• The SM-01 interface module is required for connecting VRE1/VKE1 controllers.
