<p>The 750-643 Module acts as a master for the MP bus (Multi-Point bus from Belimo/Switzerland) and allows the bus to be integrated into a higher level bus network such as ETHERNET or LONWORKS<sup>®</sup>. The MP-Bus controls HVAC actuators for dampers, regulator valves or VAV air volume controls. An additional product series for MP-Bus connection is the window ventilation system (FLS) from Belimo (MP-Bus connection for Belimo actuators, see Belimo documentation).</p><p>Devices that are equipped with an MP-Bus connection (e.g., Belimo MFT actuator series) can communicate with a higher-level control system via bus cable. The actuators have connections for sensors (temperature, humidity, on/off switch) that are also accessible via MP-Bus. An MP-Bus Master can manage up to eight slaves (actuators) and eight sensors (one sensor can be connected to each slave) via a common bus line, which considerably reduces actuator and sensor wiring (for MP-bus cable lengths, see Belimo documentation). *Documentation available in German and English.</p><p>A Belimo parameterization unit (hand-held control unit, or Belimo PC tool) can be connected to the module to configure the Belimo actuators. The enable handheld contact can be used for this. The module deactivates its MP-bus communication when the external parameterization unit is connected to this contact (or simply to the +24 V power supply).</p>
