Point Database
Overview
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.
Descriptor Address
1
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.
NGT CLG STPT 08 All except 2597 The temperature setpoint in degrees that the
controller maintains during the night periods in
cooling mode.
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 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.
