SCHEDULING
There are two options available to schedule the box. Writing a value to occCmd (A269) through a network
connection will set the box Occupied, Unoccupied, or Standby. If a network connection is not available,
the FBVi can operate on a stand-alone internal schedule.
To select the internal schedule, set intScheduleEnb (D168) to TRUE. This will allow the internal BACnet
schedule to command the unit Occupied or Unoccupied.
ALARMS
LOW AIRFLOW ALARM
If the activeAirflow (A250) is 30% below the activeFlowSetpoint (A236) for 5 minutes the
lowAirFlowAlarm (D214) will be set to TRUE.
LOW DISCHARGE AIR TEMPERATURE ALARM
If the unit is configured for a discharge air temperature sensor and the discharge air is more than 15deg
below the discharge air temperature setpoint, the lowDischAirTempAlarm (D217) will be set to TRUE.
ZONE AIR TEMPERATURE FAILURE
If the zone air temperature as detected on UI1 is below 20 or above 130 deg F,
UI1_ZoneTemperatureFailure (D124) will be set to TRUE.
DISCHARGE AIR TEMPERATURE FAILURE
If the discharge air temperature is below 20 or above 130 deg F, UI3_DischargeTempFailure (D208) will be
set to TRUE.
HIGH/LOW ZONE AIR TEMPERATURE ALARM
If the activeZoneTemp (A191) is 2 deg above the activeCoolStpt (A187) for more than 10 minutes,
highZoneTempAlarm (D225) will be set to TRUE.
If the activeZoneTemp (A191) is 2 deg below the activeHeatStpt (A188) for more than 10 minutes,
lowZoneTempAlarm (D196) will be set to TRUE.
AIRFLOW CALIBRATION ALARM
If the activeAirflow (A250) is 10% above the maxCoolFlowStpt (A228) for more than 10 minutes,
airflowCalibrationAlarm (D219) will be set to TRUE.
LEAKING DAMPER ALARM
If the damperCmd (A261) is at 0% and the activeAirflow (A250) is above the minHeatFlowStpt (A230) for
more than 10 minutes, leakingDamperAlarm (D221) will be set to TRUE.
LEAKING VALVE ALARM
If the stage 1 and 2 analog heating signals are at 0% and the discharge air temp is above 70 deg F,
leakingValveAlarm (D223) will be set to TRUE.
FAN ALARM
If a fan status is configured, and it does not see a fan status for 30 seconds when the fan is commanded
ON, fanAlarm (D127) will be set to TRUE.
HIGH CO₂ ALARM
If the CO₂ demand is over 50% for more than 10 minutes, highCO2Alarm (D194) will be set to TRUE.
