Introduction

MP-bus = multi-point bus

The MP-Bus (Multi-Point) is a simple sensor/actuator bus, which is used for certain sub-systems of the building automation system. The MP-Bus serves to control HVAC actuators for flaps, control valves and volume flow regulators from the Belimo product range. Up to eight different devices from HVAC systems can be connected to an MP-Bus master using 3-wire technology. Additionally, a sensor can be connected to each of these eight devices; the sensor is addressed by the MP-Bus. An additional range of products with an MP-Bus connection is the FLS window ventilation system by Belimo (see Belimo documentation for the connection of the Belimo drives).

The MP-Bus was developed by Belimo for connecting valves, throttle valves, air valves, fire dampers, and for window ventilation systems.
