Table 46. Lennox Proprietary Objects - Heating (Object ID: 130)
Property
Property ID
Data type and range
Access
Description
Object_Identifier
75
Integer (0-4194302)
Read Only
Numeric code that identifies the object (unique with
in Lennox BACnet Device).
Object_Name
77
character string of 1 character
(min.) to 32 characters (max.)
Read Only
Identifies the Object and is unique within the BACnet
Device.
Object_Type
79
130
(OBJECT_LNX_HEATING)
Read Only
Indicates membership in a particular object type
class.
Out_Of_Service
81
TRUE or FALSE
Read Only
Indicates whether the heating device is in service or
not.
Lennox_Object_
Installed
513
TRUE or FALSE
Read Only
Indicates whether the heating device is installed or
not. Unless the value of this property is TRUE, all
other properties of the heating object instance are
invalid.
Lennox_Object_
Running
514
Integer (0 - 100)
Read Only
Indicates that heating is not running if the value is
zero and that heating is running if a value greater
than zero (range: 0, 100 or possible values).
Lennox_Object_
Run_Time
515
Integer (0 - 4294967295) minutes
Read Only
Indicates the time heating has been running. Intern
ally, the time that heating has been running is stored
into EEPROM once every hour. Therefore, in the
event power turns off, the value returned when
power turns back on will be the last stored value.
This can result in a loss of run-time value up to an
hour for each power cycle event.
Lennox_Object_Min_
Cycle_Time
516
Integer (0 - 4294967295) seconds
Read Only
Indicates the minimum time heating must run in any
given cycle. This prevents short cycles to help pro
tect the compressor (This property does not apply to
Electric Heat Stage components).
Lennox_Object_
Cycle_Count
517
Integer (0 - 4294967295) cycles
Read Only
Indicates the number of cycles heating has been
running.
Lennox_Object_Error
518
Integer (0 - 255)
Read Only
Reports any error code heating may have en
countered. A value of 0 means no error while any
non-zero value represent an error.
Lennox_Object_
HeatType
533
Integer: Values are: 1-Gas; 2-Elec
tric; 3-Heat Pump mode
Read Only
Indicates the source of power used for heating
(range: 0, 255).

Description
Object_Identifier
75
Integer (0-4194302)
Read Only
Numeric code that identifies the object (unique with
in Lennox BACnet Device).
Object_Name
77

(OBJECT_LNX_ECONOMIZER)
Read Only
Indicates membership in a particular object type
class.
Out_Of_Service
81
TRUE or FALSE
Read Only
Indicates whether the economizer is in service or
not.
Lennox_Object_
Installed
513
TRUE or FALSE
Read Only
Indicates whether the economizer is installed or not.
Unless the value of this property is TRUE, all other
properties of the economizer object instance are
invalid.
Lennox_Object_
Running
514
Integer (0 - 100)
Read Only
Indicates that the economizer is not running if the
value is zero and that the economizer is running if a
value greater than zero (range: 0, 100 or possible
values).
Lennox_Object_
Run_Time
515
Integer (0 - 4294967295) minutes
Read Only
Indicates the time the economizer has been running.
Internally, the time that the economizer has been
running is stored into EEPROM once every hour.
Therefore, in the event power turns off, the value
returned when power turns back on will be the last
stored value. This can result in a loss of run-time
value up to an hour for each power cycle event.
