Detailed Explanation of Object
ENGLISH
Detailed Explanation of Object
1) Common to All Objects
Objects related to the air conditioner in communication are treated on the BACnet as described
below.
- Air Conditioner in Normal Communication
Other BACnet devices can access each object related to the air conditioner.
- Air Conditioner Unconnected
It seems to other BACnet devices that no objects related to the air conditioner exist.
Therefore, when the ReadProperty/WriteProperty service is received, the following ErrorPDU will
be returned.
Error class: OBJECT; Error type: UNKNOWN_PROPERTY
- Air Conditioner Communication Error
Other BACnet device can access the objects related to the air conditioners, but the
Present_Value Property will be read in a value immediately before the communication error.
2) Run/Stop (Setting)
Point number: 1
Object name: StartStopCommand_XXX (XXX: A/C unit address)
Object type: Binary Output
Meaning: This object is used to give Run/Stop commands to the air conditioner.
Present_Value property:
ACTIVE: Run command
INACTIVE: Stop command
Remarks: 1. The command executed is transmitted to the A/C regardless of the status of the A/C.
2. Present_Value property will not be used if a property has never been set in the past.
3) Run/Stop (Status)
Point number: 2
Object name: StartStopStatus_XXX (XXX: A/C unit address)
Object type: Binary Input
Meaning: This object is used to monitor the Run/Stop status of the air conditioner.
Present_Value property:
ACTIVE: Run
INACTIVE: Stop
Remarks: If there is an operation error, the Present_Value property will be set to ACTIVE
regardless of whether the A/C is in operation or not.
Installation/Owner Manual 75

Detailed Explanation of Object
4) Lock (setting)
Point number: 3
Object name: LockCommand_XXX (XXX: A/C unit address)
Object type: Binary Output
Meaning: This object is used to set the Lock of the A/C's control authority.
Present_Value property:
ACTIVE: Lock (Restricted)
INACTIVE: Unlock (Not restricted)
5) Lock (status)
Point number: 4
Object name: LockStatus_XXX (XXX: A/C unit address)
Object type: Binary Input
Meaning: This object is used to monitor the Lock of the A/C's control authority.
Present_Value property:
ACTIVE: Lock (Restricted)
INACTIVE: Unlock (Not restricted)
6) Filter Sign
Point number: 5
Object name: FilterSign_XXX (XXX: A/C unit address)
Object type: Binary Input
Meaning: This object is used to monitor the status of the filters for vent.
Present_Value property:
ACTIVE: Filter sign information is turned ON.
INACTIVE: Filter sign information is OFF.
Remarks: This object supports the Intrinsic Reporting function. When the Present_Value property
changes, the corresponding Event will be transmitted if the Event has been registered.
7) Filter Sign Reset
Point number: 6
Object name: FilterSignReset_XXX (XXX: A/C unit address)
Object type: Binary Value
Meaning: This object is used to reset the vent°Øs limit indication.
Present_Value property:
INACTIVE: Filter indication information is reset.
Remarks: 1. During a read operation of the Present_Value property, the Fliter Limit Sign Reset will
be always the same value as the Filter Limit Sign object.
2. Only if INACTIVE is written to the Present_Value property during a write operation,
the filter sign information resets ON signs and nothing will be executed even if
ACTIVE is written.
3. This object supports the Intrinsic Reporting function. When the Present_Value
property changes, the corresponding Event will be transmitted if the Event has been
registered.

ENGLISH
8) Operation Mode (Setting)
Point number: 7
Object name: ModeCommand_XXX (XXX: A/C unit address)
Object type: Multistate Output
Meaning: This object is used to set the operation modes of the air conditioner.
Present_Value property:
Indoor Vent
1: Cool HEX
2: Dry Auto
3: Fan Normal
4: Auto -
5: Heat -
Remarks: 1. The Present_Value property will be set to "1: Cool" as the default value if property
has never been set in the past.
2. The air conditioner will ignore the command to an object that does not have right to
select operation mode. Therefore, the controlled/monitored system must not use this
object for the air conditioner without the right to select operation mode.
9) Operation Mode (Status)
Point number: 8
Object name: ModeStatus_XXX (XXX: A/C unit address)
Object type: Multistate Input
Meaning: This object is used to monitor the operation modes of the air conditioner.
Present_Value property:
Indoor Vent
1: Cool HEX
2: Dry Auto
3: Fan Normal
4: Auto -
5: Heat -
10) Swing (Setting)
Point number: 9
Object name: SwingCommand_XXX (XXX: A/C unit address)
Object type: Binary Output
Meaning: This object is to set the air direction of the indoor unit.
Present_Value property:
ACTIVE: Run
INACTIVE: Stop
Installation/Owner Manual 77

Detailed Explanation of Object
11) Swing (Status)
Point number: 10
Object name: SwingStatus_XXX (XXX: A/C unit address)
Object type: Binary Input
Meaning: This object is to monitor the air direction of the A/C.
Present_Value property:
ACTIVE: Swing_On
INACTIVE: Swing_Off
12) Fan Speed (Setting)
Point number: 11
Object name: FanSpeedCommand_XXX (XXX: A/C unit address)
Object type: Multistate Output
Meaning: This object is to set the airflow of the A/C.
Present_Value property:
Indoor Vent
1: Low Low
2: Middle High
3: High Super High
4: Auto Auto
Remarks:
The A/C will disregard the command which the object which can't select the operation mode.
Therefore, controlled/monitored system shouldn't use the object which can't select the
operation mode.
13) Fan Speed (Status)
Point number: 12
Object name: FanSpeedStatus_XXX (XXX: A/C unit addresss)
Object type: Multistate Input
Meaning: This object is to monitor the airflow of the A/C.
Present_Value property:
Indoor Vent
1: Low Low
2: Middle High
3: High Super High
4: Auto Auto
