* Networkable: BACnet MS/TP or Modbus (selectable using menu)
Description
IAQ and ECM fan control applications made easy! Introducing the
new ARO series universal room controller with onboard CO2,
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.

Wiring
We strongly recommend to wire all controllers to a separate grounded transformer, and that transformer shall service only these
products. This precaution prevents interference with and possible damage to incompatible equipment.
