Demand Limit Switch 2/Dehumidify — 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 —
to configure the local display settings. A list is shown in
Table 75.
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.
Remote Control Switch Input —
input is located on the ECB-1 board and connected to TB6

— terminals 1 and 3. The switch can be used for several remote
control functions. See Table 76.
Remote Input State (Inputs
the actual real time state of the remote input.
Remote Switch Config (Configuration
— This is the configuration that allows the user to assign dif-
ferent types of functionality to the remote discrete input.
• 0 — NO REMOTE SW — The remote switch will not be
used.
• 1 — OCC-UNOCC SW — The remote switch input will
control the occupancy state. When the remote switch
input is ON, the unit will forced into the occupied mode.
When the remote switch is OFF, the unit will be forced
into the unoccupied mode.
• 2 — STRT/STOP — The remote switch input will start
and stop the unit. When the unit is commanded to stop,
any timeguards in place on compressors will be honored
first. When the remote switch is ON, the unit will be
commanded to stop. When the remote switch is OFF the
unit will be enabled to operate.
• 3 — OVERRIDE SW — The remote switch can be used
to override any internal or external time schedule being
used by the control and force the unit into an occupied
mode when the remote input state is ON. When the
remote switch is ON, the unit will be forced into an occu-
pied state. When the remote switch is OFF, the unit will
use its internal or external time schedules.

Remote Switch Logic Configuration (Configuration

SW.LG RMI.L) — The control allows for the configuration
of a normally open/closed status of the remote input switch via
RMI.L. If this variable is configured OPEN, then when the
switch is open, the remote input switch perceives the logic state
as OFF. Correspondingly, if RMI.L is set to CLOSED, the re-
mote input switch will perceive a closed switch as meaning
OFF. See Table 77.
