Chapter 3 – Point Database
Chapter 3 presents a description of the BACnet VAV Controller — Electronic Output
point database, including point descriptors, point addresses, and a listing of
applications in which each point is found.

Application
Description
CTLR ADDRESS
01
All
Identifies the controller on the FLN trunk.
APPLICATION
02
All
Identification number of the program running in the controller.
RMTMP OFFSET
03
All
Compensates for deviations between the value of ROOM
TEMP and the actual room temperature. This corrected value
is displayed in CTL TEMP. RMTMP OFFSET + ROOM TEMP
= CTL TEMP
ROOM TEMP
{04}
2
All
Actual reading from the room temperature sensor.
HEAT.COOL
{05}
All
except
2560, 2597
Current mode of operation for applications that can be in
either a heating mode or a cooling mode.
DAY CLG STPT
06
All
except
2597
The temperature setpoint in degrees that the controller
maintains during day periods in cooling mode if a room
temperature sensor setpoint dial is not present or is not used.
See STPT DIAL.
DAY HTG STPT
07
All
except
2560, 2597 The temperature setpoint in degrees that the controller
maintains during day periods in heating mode if a room
temperature sensor setpoint dial is not present or is not used.
See STPT DIAL.
NGT CLG STPT
08
All
except
2597
The temperature setpoint in degrees that the controller
maintains during the night periods in cooling mode.
NGT HTG STPT
09
All
except
2560, 2597 The temperature setpoint in degrees that the controller
maintains during the night periods in heating mode.
RM STPT MIN
11
All
except
2597
The minimum temperature setpoint in degrees that the
controller can use from the setpoint dial. This overrides any
temperature setpoint from the setpoint dial that falls below this
minimum.
RM STPT MAX
12
All
except
2597
The maximum temperature setpoint in degrees that the
controller can use from the setpoint dial. This overrides any
temperature setpoint from the setpoint dial that falls above this
maximum.
RM STPT DIAL
{13}
2
All
The temperature setpoint in degrees from the room
temperature sensor (not available on all temperature sensor
models). This setpoint will be used for control in day mode
(heating or cooling) when enabled by STPT DIAL.
STPT DIAL
14
All
except
2597
YES indicates that there is a room setpoint dial on the room
temperature sensor and it should be used as the temperature
setpoint for control in day/occupied mode. NO indicates that
the appropriate preset setpoint will be used as the
temperature setpoint for control in day/occupied heating or
cooling mode. Valid input: YES or NO.
AUX TEMP UI 1
{15}
All except 2561
Actual reading from a 10K thermistor connected to the
controller's Ul 1 input. When a thermistor is connected at Ul 1,
UI 1 is not available. See UI 1.
SUPPLY TEMP

2561
Actual reading from a 10K thermistor connected to the
