Carrier 3V VVT 33ZCVVTZC-01 Installation And Start-Up Instructions Manual page 32

HEAT TYPE -- This configuration is used to define the type
of heat installed on the tenninal. A 0 or 1 is equal to None. A 2
is equal to Two Position. A 3 is equal to Staged Electric. A 4 is
equal to Modulating/CV. A 5 is equal to combination.
Heat Type: Range 0 to 5
Default Value 0
HEATING LOOP PARAMETERS-- The heating loop
gains and stmt value define how the tenninal will respond to
deviations in measured space temperature in order to control to
the heat set point.
The Proportion_fl Gain is calculated each time the space
temperature is compmed to the heat set point. As the error
fiom set point goes to zero, the Proportional Gain will also go
to zero.
The Integral Gain is a running summation of all integral
terms since the loop started. This has the affect of trimming off
any offset from set point which might occur if only the
Proportional Gtfin existed. Normally a proportional loop with
no Integral Gain would require frequent adjustments of the
st_uting value to eliminate the offset as loading conditions on
the room change.
The Derivative Gain is not needed. This term tends to
nullify large changes in file Proportional Gain for dmnpened
response.
The Start V;flue is the initi_fl value that is then modified by
the Error terlns of the PID calculation.
Heating Ix_op Parameters
Proportional Gain: Range 00.0 to 99.9
Default Value 8.0
Integnfl Gain: Range 00.0 to 99.0
Default Value 3.0
Derivative Gain: Range 00.0
Default Value 0.0
Start Value: Units F (C)
Range 40 to 125
Default Value 80
DUCTED HEAT-- The Ducted Heat configuration is used
to configure the terminal for ducted heat. If a local heat source
is in the duct and requiles airflow to provide heat, set the Duct-
ed Heat configuration for yes.
Ducted Heat: Range No/Yes
Default Value Yes
MAXIMUM TEMPERATURE -- This configuration is used
to configure the maximum supply-air temperature desirable for
heating the space. This will cause the heat to be modulated or
cycled using this v;flue as the maximum temperature of the air
to be supplied.
Maximum
Temperatme: Units F (C)
Range 40 to 200
Default Value 110
NUMBER OF ELECTRIC STAGES -- This configuration
is used to define the number of stages of electric heat controlled
by the zone controller
Number of
Electric Stages: Range 1 to 3
Default Value 1
HEAT ON DELAY -- The Heat On Delay configuration is
used to define a delay from the time a pm'allel terminal fan is
st;u'ted until the heat is activated.
Heat On Delay: Units minutes
Range 1 to 60
Default Value 2
FAN OFF DELAY- The Fan Off Delay configuration is
used to define a delay time. The delay time is from when the
heat is deactivated On a parallel terminal) until the parallel fan
is deactivated. This allows the fan to circulate air and remove
the residual heat from the heat source.
Fan Off Delay: Units minutes
Range 1 to 15
Default Value 2
TWO-POSITION HEAT LOGIC-- This configuration is
used for controlling a normally closed or normally open valve
for hot watel: Use normal logic if the valve is normally closed.
Use inverted logic if the valve is normally open.
Two Position
Heat Logic: Range Normal/Invert
Default Value Normal
SYSTEM CALL FOR HEAT'? -- This decision is used
whenever auxiliary heat is available and can handle the heat
load for the zone without calling the system for heat. This
prevents the entire building from going to heat for one cold
room. Configure this decision to No when tiffs zone should not
be allowed to call file _fir source for heat.
System Call
For Heat: Range No/Yes
Default Value Yes
SUPPLEMENTAL HEAT LOCKOUT TEMP -- This config-
uration is the temperature setting that is compared to the
outside _firtemperature to make a determination if supplemen-
tal heat tit the zone will be allowed to operate.
Supplement_fl Heat
Lockout Temp: Units F
Range -40.0 to 140 F
Default 140
SYSTEM PILOT AVERAGING-- This configuration de-
termines how multiple sensors are averaged with the System
Pilot. A 0 equals System Pilot only. A 1 equals with one T55
sensoc A 2 equals with four T55 sensors. A 3 equals with nine
T55 sensors.
System Pilot
Averaging: Range 0-3
Default Value 0
SPACE TEMPERATURE TRIM --This configuration is used
to trim a space sensor which might need calibration. For
exmnple, if the temperature displayed is two degrees above the
value measured with calibrated test equipment, input a value of
-2.0.
System Pilot
Trim: Units delta F (delta C)
Range -9.9 to 9.9
Default Value 0.0
SUPPLY AIR TEMPERATURE TRIM --This configuration
is used to trim a supply air sensor which might need calibra-
tion. For example, if the temperature displayed is two degrees
above the value measured with calibrated test equipment, input
a value of-2.0.
Supply Air Temperature
Trim: Units delta F (delta C)
Range -9.9 to 9.9
Default Value 0.0
LOCAL SAT INSTALLED-- This configuration tells the
zone controller if a local SAT sensor is installed. When config-
ured as "Yes", the zone controller will use this information to
determine if the local SAT sensor has failed or is out of range
and has sensed an alarm. When configured to "No", the SAT
point will read 0.0 ° F and the SAT alann condition will be
clemed.
Local SAT
Installed: Range No/Yes
Default Yes
