BS2-VR-01 Volume flow and pressure controller module
⇒
see page 2 (EnEV, MBO)
The volume flow and pressure controller module facilitates connection of up to four electronic volume flow and/or
pressure controllers (manufacturer WILDEBOER) using spring terminals.
⇒
see table 1
The module is used to optimise the energy efficiency of a ventilation and air conditioning system. For this purpose, the
parametrisable calendar control can be used to set the supply air and exhaust air volume flow rates of connected con-
trollers with timer control to suit the building usage. Sequence controls can also be used to make a requirement-based
setting by integrating presence sensors and CO2 switches. The connected controllers can be overridden by integrating
window contacts so that they close as soon as a window is opened, for instance. The reduction in the mean outdoor
air volume flow rate of the system which is achievable as a result makes for an optimisation in the required energy.
Monitoring
functions facilitate the graphic analysis of the ventilation ratios in the system. Adjustments can be made
at any time from a central point.
•
Communication between the module and the connected controllers via RS485 or MP-Bus.
•
24 V DC operating voltage for the connected controllers from the volume flow and pressure controller module.
•
Existing VRE1 or VKE1 volume flow controllers can be connected via SM-01 interface modules.
•
Connected controllers are detected by the module, and it reads out their parameters, which are available for factory
pre-order.
