Table 69 — CONFIGURATION — TRIM Submenu
Outdoor Air Temperature Sensor Trim (
OAT.T) —This vari-
able is used to adjust the outdoor air temperature sensor read-
ing. The sensor reading can be adjusted ± 10° F to match the
actual measured temperature.
Space Temperature Sensor Trim (
SPT.T) — This variable is
used to adjust the space temperature sensor reading. The sensor
reading can be adjusted ± 10° F to match the actual measured
temperature.
Circuit A Saturated Condenser Temperature Trim (
CTA.T) —
This variable is used to adjust the saturated condenser tempera-
ture sensor reading for circuit A. The sensor reading can be
adjusted ± 30° F to match the actual measured temperature.
Circuit B Saturated Condenser Temperature Trim (
CTB.T) —
This variable is used to adjust the saturated condenser tempera-
ture sensor reading for circuit B. The sensor reading can be
adjusted ± 30° F to match the actual measured temperature.
Suction Pressure Circuit A Trim (
SP.A.T) — This variable is
used to adjust the suction pressure sensor reading for circuit A.
The sensor reading can be adjusted ± 50 psig to match the actu-
al measured pressure.
Suction Pressure Circuit B Trim (
SP.B.T) — This variable is
used to adjust the suction pressure sensor reading for circuit B.
The sensor reading can be adjusted ± 50 psig to match the actu-
al measured pressure.
4to20mAInputs
— There are a number of 4 to 20 mA in-
puts which may be calibrated. These inputs are located in
Inputs → 4-20.Theyare:
• SP.M.T — static pressure milliamp trim
• BP.M.T — building pressure milliamp trim
• OA.M.T — outside air cfm milliamp trim
• RA.M.T — return air cfm milliamp trim
• SA.M.T — supply air cfm milliamp trim
Discrete Switch Logic Configuration — The SW.LG
submenu is used to configure the normally open/normally closed
settings of switches and inputs. This is used when field-supplied
switches or input devices are used instead of Carrier devices. The
normally open or normally closed setting may be different on a
field-supplied device. These points are used to match the control
logic to the field-supplied device.
The defaults for this switch logic section will not normally
need changing. However, if a field-installed switch is used that
is different from the Carrier switch, these settings may need
adjustment.
Settings for switch logic are found at the local displays
under the Configuration
→ SW.LG submenu. See Table 70.
Filter Status Input — Clean (
FTS.L) — The filter status in-
put for clean filters is set for normally open. If a field-supplied
filter status switch is used that is normally closed for a clean
filter, change this variable to closed.
IGC Feedback — Off (
IGC.L) — The input for IGC feed-
back is set for normally open for off. If a field-supplied IGC
feedback switch is used that is normally closed for feedback
off, change this variable to closed.
Remote Switch — Off (
RMI.L) — The remote switch is set
for normally open when off. If a field-supplied control switch
is used that is normally closed for an off signal, change this
variable to closed.
Economizer Switch — No (
ECS.L) — The economizer
switch is set for normally open when low. If a field-supplied
economizer switch is used that is normally closed when low,
change this variable to closed.
Fan Status Switch — Off (
SFS.L) — The fan status switch
input is set for normally open for off. If a field-supplied fan
status switch is used that is normally closed, change this
variable to closed.
Demand Limit Switch 1 — Off (
DL1.L) — The demand
limit switch no. 1 input is set for normally open for off. If a
field-supplied demand limit switch is used that is normally
closed, change this variable to closed.
Demand Limit Switch 2 — Off (
DL2.L) — The demand
limit switch no. 2 input is set for normally open for off. If a
field-supplied demand limit switch is used that is normally
closed, change this variable to closed.
IAQ Discrete Input — Low (
IAQ.L) — The IAQ discrete in-
put is set for normally open when low. If a field-supplied IAQ
discrete input is used that is normally closed, change this vari-
able to closed.
Fire Shutdown — Off (
FSD.L) — The fire shutdown input is
set for normally open when off. If a field-supplied fire shut-
down input is used that is normally closed, change this variable
to closed.
Pressurization Switch — Off (
PRS.L) — The pressurization
input is set for normally open when off. If a field-supplied pres-
surization input is used that is normally closed, change this
variable to closed.
Evacuation Switch — Off (
EVC.L) — The evacuation input is
set for normally open when off. If a field-supplied evacuation in-
put is used that is normally closed, change this variable to closed.
Smoke Purge — Off (
PRG.L) — The smoke purge input is set
for normally open when off. If a field-supplied smoke purge in-
put is used that is normally closed, change this variable to closed.
Display Configuration — The DISP submenu is used
to configure the local display settings. A list is shown in
Table 71.
Test Display LEDs (
TEST) — This is used to test the opera-
tion of the ComfortLink™ display.
Metric Display (
METR) — This variable is used to change
the display from English units to Metric units.
Language Selection (
LANG) — This variable is used to
change the language of the ComfortLink display. At this time,
only English is available.
Password Enable (
PAS.E) — This variable enables or dis-
ables the use of a password. The password is used to restrict
use of the control to change configurations.
Service Password (
PASS) — This variable is the 4-digit nu-
meric password that is required if enabled.
