The BAS can command occupancy, unit stop, fan, ventilation, heating and the Y1/Y2/W1/W2 calls, and write zone, supply air, duct static, building pressure and economizer setpoints and a BAS zone temperature. Read-only points cover temperatures, humidity, CO2, static pressures, damper and VFD outputs, compressor and heat stage status, run hours, faults and the unit mode.",
