IN485FGL001I000 Gateway

7.2. Occupancy Function

IMPORTANT
The Occupancy function is only available for BACnet.
The Occupancy function determines the AC unit's behavior depending on the presence or absence of people in
the room. This signal is processed directly in the Intesis gateway and has the capacity to modify three parameters
of the AC system: Setpoint, Mode, and On/Off.
IMPORTANT
This function requires a presence sensor on the control system (BMS) side, which determines the
state of the Occupancy object:
• Occupied: Someone is in the room.
• Unoccupied: No one is in the room.
• Disabled: The function is disabled
Besides the Occupancy object, and to adjust the settings of the Occupancy function, the gateway offers these
BACnet objects:
• Occupancy Cool Setpoint (OCS): Setpoint temperature when the AC unit is in cool mode and someone is
present in the room.
• Unoccupancy Cool SetPoint (UCS): Setpoint temperature when the AC unit is in cool mode and no one is in
the room.
• Occupancy Heat Setpoint (OHS): Setpoint temperature when the AC unit is in heat mode and someone is
present in the room.
• Unoccupancy Heat SetPoint (UHS): Setpoint temperature when the AC unit is in heat mode and no one is in
the room.

NOTICE
The minimum difference between Cool and Heat setpoints must be 2°C / 4°F.
• Occupancy Continuous check: It determines when the gateway checks the room's occupancy:
– If this object's value is 1 (active), the gateway checks the occupancy when the occupancy status and the
room's temperature change.
