 "summary": "These Modine direct-fired make-up air units use a Distech ECB-403 programmable controller that joins a BACnet MS/TP trunk. The BMS can turn the unit fan on, off or auto, write occupied and unoccupied heat and cool setpoints, set the building pressure setpoint and economizer commands, and override space temperature, building pressure and occupancy with network values. Alarms (dirty filter, low temperature, sensor faults, burner lockout, motor not responding) are multistate values.",

  "The manual calls Table 11.1 'typical' system variables; units with LonTalk (model digit 14 = L) need factory guidance.",

  "network_SpaceTemperature, network_BuildingPressure and network_Occupancy override local values; write null (relinquish) to return to automatic control.",
  "network_ManualEconPercent is not available with the building pressure option.",
  "The enumeration texts for the Filters and SensorReliability state sets are not printed in the BACnet table; the display menu shows the sensor alarms as no-fault / open / short."
