When CXTQ is in heat mode, but is not calling for heat or is
set for fan only mode, the indoor blower fan may stop despite
the remote controller user settings.
1. When the system is in heating mode while operating
during low ambient temperatures, the system may stop
the indoor blower fan in accordance with the following
conditions in order to protect the system components.
AMBIENT
TEMPERATURE
BLOWER FAN OPERATION
˃
20°F
Blower fan can be on/off (depending on
user preference)
20°F ~ 5°F
Blower fan may be off (depending on user
preference or operating conditions)
<5°F
Fan will be off
Table 1
Note:
During heat mode, the factory default settings of the
CXTQ coil will not operate the blower fan when there is not a
call for heating. This will occur regardless of the ambient
temperature as long as the field settings have not been
changed.
The indoor blower fan does not obey the user specified fan
speed of remote controller.
1. In gas combustion heating mode, the air flow rate is
dependent upon the gas combustion strength. The indi-
cation of the fan speed on the remote controller display
will be valid for only heat pump operation.

PRECAUTIONS
If the following occurs, contact your dealer.
•
Any abnormalities in the operation of the heat pump
such as smoke or fire could result in severe injury or
death.
Turn off the power and contact your dealer immediately
for instructions.
_______________________________________________
Safety device operation, such as fuses, breaker, GFCI, etc.
is often unstable.
Take the following actions before contacting an HVAC con-
tractor.
1. Turn off the disconnect switch.
2. If the disconnect switch does not work properly, turn off
the main power switch.
Water leaks out from the cased coil.
Take the following actions before contacting an HVAC con-
tractor.
1. Stop the operation.
Error message is displayed on the remote controller.
1. See the remote controller operation manual and cased
coil installation manual for details.
2. Inform your Daikin dealer of the details being displayed
on the remote controller.

GAS FURNACE LOCKOUT RESET
Furnace lockout is characterized by a non-functioning
furnace (circulator blower may be running continuously)
providing a diagnostic LED code located on the furnace
board (contact your Daikin dealer for further assistance).
Lockout results when a furnace control detects abnor-
mal conditions. If the furnace is in “lockout,” the follow-
ing methods can be used to clear the error code.
a.
Turn the remote controller off to clear the error. If the
error isn’t cleared, go to next step.
b.
Set a setting temperature to maximum, then turn the
remote controller on.
c.
Turn the remote controller off.
d.
After performing c., turn the remote controller on after
approximately 15 seconds.
The procedures b, c, and d will not work during certain out-
door unit operations, i.e. defrost, start-up, stop a compres-
sor, service mode etc.
If the LED of the ON/OFF button is flashing when you turn
the remote controller on, you cannot clear the error with this
method. In that case, the error must be cleared using the
gas furnace. Refer to the gas furnace operation manual for
more details.
