Sequence of Operation
Occupancy Control
The nvoEffectOccup (nvoFP02) is managed based on nviSchedule and RoomOccupancy (BV2)
The nviSchedule is usually received from the network and the RoomOccupancy (BV2) is based on
motion detection and occupancy overrides.
The following table describes the sequence of operation for the occupancy control:
nviSchedule RoomOccupancy (BV2) nvoEffectOccup (nvoFP02)

1. If no motion is connected and schedule is unoccupied, the bypass mode is activated for 60 min-
utes if the room occupancy is set to occupied (EC-Smart-Vue, EC-Smart-Sensor and EC-Smart-
Comfort).
Motion Hold Time
After the last occupancy detection, RoomOccupancy (BV2) is maintained to OCCUPIED for 15 min-
utes (motion hold time default value). If no detection happens during this periodnvoEffectOccup
(nvoFP02) is set to STANDBY (if nviSchedule = OCCUPIED) or UNOCCUPIED (if nviSchedule = UN-
OCCUPIED). When nviSchedule is UNOCCUPIED, this motion hold time is divided by 3.
Temperature Setpoint Control
The actual setpoints nvoEffectHeatSp and the nvoEffectCoolSp are computed according to nvoEffec-
tOccup (nvoFP02)nvoSetPtOffset
