Description
IAQ and ECM fan control applications made easy! Introducing the
new ARO series universal room controller with onboard CO
VOC, temperature and humidity sensors, selectable application
control profiles, up to 4 simultaneous control loops, and seamless
control of a 0-10 Vdc ECM fan. All of this in one wall-mounted
room controller.
The AROB series networkable controller operates over an RS‐485
network using the BACnet MS/TP or Modbus protocol to
exchange information with a Building Management System.
