Occupancy
Occupancy function is used to determine how the Air Conditioner unit will be set depending on the presence or
absence of people in the room. Remember that the occupancy signal needs to be fed by an external sensor which
indicates if there is presense or not (occupancy). This signal is processed directly in the IntesisBox and modifies 3
parameters from the AC system: Setpoint, Mode and On/Off.
In order to adjust the settings to the current mode (Heat or Cool), the gateway offers 6 different BACnet objects:
•
OccupiedCoolSetPoint
•
OccupiedHeatSetPoint
•
UnoccupiedCoolSetPoint
•
UnoccupiedHeatSetPoint
•
OccupancyContinousCheck
•
UnoccupiedDeadbandAction
Occupancy/Unoccupancy Cool Setpoint (OCS/UCS):
Default value for setpoint temperature to be set when
Occupancy/Unoccupancy is enabled and current mode is cool. UCS must always be greater or equal to OCS.
Difference between OCS and OHS must be greater or equal to 2ºC/4ºF.
Occupancy/Unoccupancy Heat Setpoint (OHS/UHS):
Default value for setpoint temperature to be set when
Occupancy/Unoccupancy is enabled and current mode is heat. UHS must always be smaller or equal to OHS.
Difference between OCS and OHS must be greater or equal to 2ºC/4ºF.
Occupancy Continous check:
This checkbox is used to determine if the gateway will check the occupancy
conditions constantly (check) or not (unchecked) by default. That means that with the the checkbox active, conditions
are checked on each change of the temperature too, while if unchecked, this is only checked when the occupancy
status changes.
Unoccupied Deadband Action:
This determines the action to be taken while the ambient temperature is in between
the deadband. If unchecked, indoor unit will turn off and if checked it will remain on.
When
occupancy mode is active
(there is presence in the room), according to current room temperature,
mode
,
setpoint
and
on/off
will be set to:

On/Off
Room temperature > OCS
Current OCS value

Room temperature < OHS
Current OHS value
Heat
On
OCS < Room temperature > OHS
OCS/OHS depending on current mode
(If Fan or Dry mode is active, no setpoint is sent)

When
unoccupancy mode is active
(there is no presence in the room), according to current room temperature,
mode
,
setpoint
and

Unoccupancy Cool SetPoint (UCS)
