• Unit status: Indicates if BACnet data is being passed between the HVAC equipment and
the zone sensor.
– Online: data is being passed.
– Offline: data is not being passed.
• MAT low limit: On – economizer is being limited due to low mixed
air temperature. Off – normal temp.
• DAT sensor fail: On – sensor fail. Off – sensor normal.
• OAT sensor fail: On – sensor fail. Off – sensor normal.
• RAT sensor fail: On – sensor fail. Off – sensor normal.
• MAT sensor fail: On – sensor fail. Off – sensor normal.
Note: Symbio 800 does not use the mixed air sensor for economizer control.
