Ventilation control unit MultiBox IV

with displayfor fanssmart

The MultiBox IV is a sixth generation ventilation control unit based on the latest microprocessor technology and a large easy-to-use touch color screen. It secures optimized ventilation solution considering both energy, CO2, and noise. It sends service messages and define the startup time and output voltage. More opportunities in one box and easy to use. MultiBox IV can be used for pressure measurement, control, regulation, and monitoring of alarm systems for process ventilation in the pressure range from 10 to 4000 Pa. MultiBox IV is especially useful for dynamic pressure regulation in installations with throttle valve and/or a fan with frequency inverter. The desired pressure or flow (pressure difference) is encoded as a fixed point. The built-in regulator will adjust the damper or frequency inverter. The alarm is activated if the regulation does not hold pressure/flow within the selected alarm limits. Easy to install with a large color touch screen Speed regulation of fan with frequency inverter through an analog 0 to 10V DC signal Control of 24V motor damper On/off control of 24V motor damper Monitoring of pressure/flow with acoustic and visual alarm Pressure measurement and other practical information is shown on the display during operation Built-in pressure transducer for the range from 10 to 4000 Pa. 230V connection
