Cooling
Test
The cooling
(COOL)
submenu
is used to change
output
status for
testing the cooling
function.
The fans (FANS)
and heating
(HEAT)
service
test outputs
are reset to OFF for the cooling
service
test.
The digital scroll controller
power test (CTLR)
turns on and off the
compressor
controller.
The compressor
capacity
test (CPAC)
is
used to run the compressor
at a desired
capacity
of 15% to 100%.
If a capacity
is chosen
between
1 and 14, the capacity
will be set to
15%.
The
outdoor
fan will turn
on to high
speed
when
the
compressor
capacity
is 15% or greater.
The indoor
fan speed will
default
to
supply
fan
maximum
speed
(FS.MX)
when
the
compressor
capacity
test is first activated.
The cool test fan speed
(F.SPD)
is used to change
the fan speed
while
the compressor
is
running.
All normal
cooling
alarms and alerts are functional.
IMPORTANT:
When
charging
the unit,
both
the compressor
capacity
test and the cool test fan speed should be set to 100%.
Heating
Test
The heating
(HEAT)
submenu
is used to change
output
status for
the individual
heat stages,
gas or electric.
The fans (FANS)
and
cooling
(COOL)
service
test outputs
are reset
to OFF
for the
heating
service
test.
Indoor
and
outdoor
fans
are
controlled
normally
to maintain
proper
unit operation.
The indoor
fan speed
will run at the configured
max speed FS.MX.
All normal
heating
alarms and alerts are functional.

PARTY CONTROL
Third
party
controls
may
interface
with
the unit ComfortLink
TM
controls
through
the
connections
described
below.
See
other
sections
of these
instructions
for more
information
on the related
unit control
and configurations.
Remote
Occupancy
The remote
occupancy
input
is provided
on the field connection
terminal
board
(TB1).
The
Remote
Occupancy
Switch
configuration,
Configuration--,UNIT--,RM.SW,
identifies
the
normally
open
or normally
closed
status
of this
input
when
unoccupied.
• 5 = 24 VAC signal input
• 6 = 24 VAC source for dry contact
Fire Shutdown
The fire shutdown
input is provided
for unit shutdown
in response
to a fire alarm
or smoke
detector.
The Fire
Shutdown
Switch
configuration,
Configuration--,UNIT--,FS.SW,
identifies
the
normally
open or normally
closed status of this input when there is
no fire alarm.
Input at field connection
terminal
board (TBI)
• Fire Shutdown
1 = 24 VAC source for dry contact
• Fire Shutdown
2 = 24 VAC signal input
Alarm Output
The
alarm
output
is provided
on the field connection
terminal
board
(TBI)
to indicate
a current
alarm status. The output
will be
24VAC
if a current alarm exists.
• C = 24 VAC common
• X = 24 VAC signal output
Economizer
Monitoring
On field terminal board
(TBI),
terminals 8, 9, and 10 can be used
to monitor
economizer
position
from
a third party control
system.
See economizer
operation
section
for additional
information.
In digital
mode
(E.CTL
= 1 or 2), the economizer
commanded
position
can be read as a 2-10v
or 4-20mA
signal.
TBI-8
and
TBI-9
are used as follows:
• To read a 2-10v
signal,
disconnect
the violet wire on
TBI-J10-8
and place volt meter device across TBI-8
and
TBI-9.
• To read a 4-20mA
signal,
disconnect
the violet wire on
TBI-JI0-8
and the 50092 resister at TBI-J10-6.
Place amp
meter device between
TBI-8
and TBI-9.
In analog mode
(E.CTL
= 3), the economizer
position
can be read
as a 2-10v
feedback
signal across TBI-10
and TB1-9
at any time.
IMPORTANT:
The
violet
wire
and
50092
resister
must
be
connected
at the J10 connector
as originally
wired
to operate
the
economizer
in analog mode.
Economizer
Damper
Control
For units with
the economizer
option
or accessory
and the ECB
control
board,
the damper
position
can be
directly
controlled
through
the IAQ sensor
input
provided
on the field connection
terminal
board.
The
IAQ
Analog
Input
configuration,
Configuration--,AIR.Q--,IA.CF
will
have
to set to 3 (Control
Minimum
Position).
When
IA.CF
= 3, an external
4 to 20 mA
source
is used to move the damper
0% to 100% directly.
Terminal
2 = 4-20mA
+ signal
Terminal
3 = 4-20mA
- common
IMPORTANT:
In
this
mode
preset
minimum
positions
configurations
are not valid. The damper
position
may exceed
the
input position
to provide
economizer
cooling
and CO2 sensor input
can not be used for DCV control.
Refer to the Indoor
Air Quality
operation
section
for more information.
