Table 5 — Alarm Configuration Table
UNOCCUPIED SPACE TEMPERATURE LOW LIMIT
— This configuration defines the lowest temperature that the
unoccupied space can be before an alarm is generated.

UNOCCUPIED SPACE TEMPERATURE HIGH LIMIT
— This configuration defines the highest temperature that the
unoccupied space can be before an alarm is generated.

occupied space can have before an alarm is generated.
Demand Control Ventilation

Terminal Service Configuration Table —
The Ter-
minal Service Configuration Table (CONFIG) contains
decisions used to configure the main settings for the zone
controller. This includes Terminal Type, Primary Inlet Size,
and gains for the damper and heating PID loops. Decisions
regarding auxiliary heat are made in this table and up to
10 temperature readings can be configured for room tempera-
ture sensor averaging. SPT and SAT sensor trimming are done
here as well. See Table 6.
TERMINAL TYPE — This configuration is used to indicate
the terminal type that the zone controller is installed on. A 1 is
for Single Duct terminals, a 2 is for Parallel Fan terminals, and
a 3 is for Series Fan terminals.
Terminal Type:
Range
1 to 3
Default Value
1
PRIMARY INLET SIZE — The Primary Inlet Size configu-
ration is used to input the inlet diameter of the terminal if used
with a round inlet. The Inlet Area configuration is used for oval
or rectangular inlets. The zone controller will use the larger val-
ue for demand weighting if both values are configured. If both
inlet size and inlet area are zero, then the damper will not be in-
cluded in the average demand calculations.
NOTE: Carrier sizes 12, 14, and 16 are oval.
Primary Inlet Size
(Inlet Diameter): Units
Inches
Range
0.0 to 24.0
Default Value
6.0
INLET AREA — The Inlet Area configuration is used if the ter-
minal has an oval or rectangular inlet. The Primary Inlet Size
configuration is used for round inlets. The zone controller will use
the larger value for demand weighting if both values are config-
ured. If both inlet size and inlet area are zero, then the damper will
not be included in the average demand calculations.
Inlet Area:
Units
Square Inches
Range
0.0 to 500.0
Default Value
0.0
DAMPER LOOP PARAMETERS — The loop gains and
start value define how the terminal will respond to deviations in
measured temperature in order control to the damper position.
The Proportional Gain is calculated each time the airflow is
compared to the active airflow set point. As the error from set
point goes to zero, the proportional term will also go to zero.
The Integral Gain is a running summation of all integral
terms since the loop started. This has the effect of trimming off
any offset from the set point which might occur, if only the
proportional term existed. Normally a proportional loop with
no integral term would require frequent adjustments of the
starting value to eliminate the offset as static pressure and other
conditions change.
The derivative gain tends to nullify or accelerate the chang-
es in the proportional gain depending on the size of the error
from the set point. This allows the damper to respond faster
and more efficiently to accurately maintain the space tempera-
ture set points. The Start Value is the initial value that is then
modified by the error terms of the PID calculation.

CLOCKWISE ROTATION — This configuration is used to
define what effect a clockwise rotation of the actuator will have
on the damper. If the actuator rotates clockwise to closed posi-
tion, the configuration should be set to Close. If the actuator ro-
tates clockwise to open, the configuration should be set to
open. This configuration is used to change the rotation of the
actuator so that the damper transducer calibration will work
properly. The actuator does not have to be re-installed nor any
switches changed to reverse the action.
