Table 65 — Sensor Trim Configuration
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 66.
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.
Enthaply Input — Low (ENT.L) — The enthalpy input is set
for normally closed when low. If a field-supplied enthalpy
switch is used that is normally open when low, change this
variable to open.
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 evacua-
tion input 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
input is used that is normally closed, change this variable to
closed.
Dehumidify Switch — Off (DH.LG) — The dehumidify in-
put is set for normally open when off. If a field-supplied
dehumidify input 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 67.
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.
