DEMAND VENTILATION — This variable displays the
amount of CO
2
in the air as read from the demand ventilation
sensor if DCV (demand control ventilation) is specified.
NOTE: The zone controller either reads relative humidity or
demand ventilation depending on what is specified in the Con-
trol Options configuration. If this point is not specified, it is
available for use as a software point.

PRIMARY AIR TEMPERATURE — Primary air tempera-
ture from sensor (10 k
Ω
, Type II), located in main trunk of
ductwork for supply air provided by the air source equipment.
Used for linkage coordination of linked systems, not local
operation.

HEAT (ENABLE/DISABLE) — Provides enable/disable func-
tion for local heat at the terminal. When enabled the Local heat
capacity function will run to operate the terminal heat.

REMOTE START — This variable displays the value of the
remote timeclock input point that can be used for occupancy
override. The input point is configured as normally open or
normally closed in the Terminal Service Configuration Table.
The occupancy mode of the zone controller will depend on the
configuration of the timeclock input and the value of the input
as follows:
The user can override the zone controller’s unoccupied
mode by forcing Remote Start to
On
. The default state (Nor-
mally Closed and Off) is such that it may be used by controllers
that do not have remote timeclock wiring.

CONFIGURATION TABLES
The following sections describe the computer configuration
screens which are used to configure the zone controller. The
screens shown may be displayed differently when using differ-
ent Carrier software. See Table 5.
Alarm Configuration Table —
The Alarm Configura-
tion Table (ALARMLIM) contains decisions used to configure
the alarm settings for the zone controller. This includes
re-alarm time, routing of alarms, limits for space temperature
and demand control ventilation.
RE-ALARM TIME — This decision is used to configure the
number of minutes the zone controller will wait before an alarm
condition which has not been corrected will be re-transmitted
on the communications network. Re-alarming of an alarm
condition will continue until the condition no longer exists.
Alarm Re-Alarm
Time:
Units
Minutes
Range
0 to 1440
Default Value
0 (Disabled)
ALARM ROUTING CONTROL — This decision indicates
which Carrier Proprietary Network system software or devices
will receive and process alarms sent by the zone controller. This
decision consists of eight digits each can be set to zero or one. A
setting of 1 indicates alarms should be sent to this device. A
setting of zero disables alarm processing for that device.
Currently the corresponding digits are configured for the
following devices: first digit — user interface software; second
digit — autodial gateway or Telink; fourth digit — alarm
printer interface module; digits 3, and 5 through 8 — unused.
Alarm Routing
Control:
Range
00000000 to 11111111
Default Value
00000000
SPACE TEMPERATURE OCCUPIED HYSTERESIS — This
configuration defines the range above the occupied high set
point and below the occupied low set point that the space
temperature must exceed for an alarm condition to exist during
occupied hours.
