Legacy Rules

• NIST APAR2 - Outdoor air fraction out of acceptable range (Mode 1 - Heating)
• NIST APAR20 - Cooling coil valve is frequently fully open (Mode 4 - Mech. Cooling w/min OA)
• NIST APAR21 - Heating/cooling/mixed air damper control is overlapping (Mode 5 - Unknown Occupied Mode)
• NIST APAR22 - Heating/cooling control is overlapping (Mode 5 - Unknown Occupied Mode)
• NIST APAR23 - Heating/mixed air damper control is overlapping (Mode 5 - Unknown Occupied Mode)
• NIST APAR24 - Cooling/mixed air damper control is overlapping (Mode 5 - Unknown Occupied Mode)
• NIST APAR25 - Persistent supply air temperature error exists (All Occupied Modes)
• NIST APAR26 - Sensor fault/miscalibration: mixed air temp too low (All Occupied Modes)
