Chapter 4—Point Database
Overview
Chapter 4 presents a description of the ATEC point database, including point descriptors,
point addresses, and a listing of applications in which each point is found. Applications in
parentheses are slave modes.
Description of Points
Descriptor Address
Application Description
CTLR ADDRESS
01 All Identifies the controller on the FLN trunk. Addresses 0 to 98
are valid; 0 to 31 are typically used.
APPLICATION
02 All Identification number of the program running in the
controller.
CHK STATUS
03 All Results from the automated checkout procedure that runs
when CHK OUT (Point 10) is commanded to YES. See
Chapter 2 and Chapter 3—Applications for details.
ROOM TEMP
04 All Actual reading from the room temperature sensor.
HEAT.COOL
05 2501, 2521,
2522, 2523,
2524, 2526
Current mode of operation for applications that can be in
either a heating mode or a cooling mode.
DAY CLG STPT
06 All except slave
modes
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 (Point 14).
DAY HTG STPT
07 2501, 2521,
2522, 2523,
2524, 2526
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 (Point 14).
NGT CLG STPT
08 All except slave
modes
The temperature setpoint in degrees that the controller
maintains during the night periods in cooling mode.
NGT HTG STPT
09 2501, 2521,
2522, 2523,
2524, 2526
The temperature setpoint in degrees that the controller
maintains during the night periods in heating mode.
CHK OUT
10 All When this point is commanded to YES, the controller runs
the automated checkout procedure. The results appear in
CHK STATUS (Point 3).
RM STPT MIN
11 All except slave
modes
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.
