Remote Controller Service Mode Functions
Note: While in the INQUIRY mode, refer to the following
instructions to enter SERVICE mode for the applicable codes.
Below is a list of INQUIRY modes and serviceable functions.
a. Before using the remote’s service functions, turn OFF the
indoor unit with the remote.
b. Turn OFF the power to the outdoor unit for 2 minutes. Turn
the power back ON.
c. Remove the batteries from the remote and wait for the remote
screen to clear. Within 30 seconds of replacing the batteries, use
UP or DOWN to scroll through the INQUIRY modes.
d. To enter the SERVICE mode for an applicable INQUIRY
mode, press ON/OFF for 2 seconds.
e. After SERVICE adjustments have been made, press ON/OFF
for 2 seconds to exit the SERVICE mode and return to the
INQUIRY mode.
f. Once operations in the INQUIRY mode are complete, press
ON/OFF and FAN SPEED for 2 seconds to exit. All buttons
on the remote controller are disabled for 60 seconds
g. To ensure changes are locked, power down the outdoor unit for
three (3) minutes after all the service mode changes are made.
Read and understand the function changes you wish to make in
advance. Neither the indoor unit nor the remote control displays
the new level of any of the changes made while in the INQUIRY
mode. Be sure to document the changes you've made to the
system's programming using the INQUIRY mode. Once you
complete the changes and exit the INQUIRY mode, if additional
changes are made to the programming, the system will not show
the new previously set level(s).
For example, when you first access CODE 22, Heating
Temperature Compensation, the remote control display
defaults to 0. If you change it to -2, then save and exit out of the
INQUIRY mode, the next time someone goes back in and
accesses CODE 22, the remote’s display will not display -2.
Instead it will show 0 because that's the default. If you are unsure
of the previous changes, due to a lack of documentation, you
could press the DOWN symbol to the maximum change range of
-6, then press the UP symbol until you are back to 0, and make
the new adjustments accordingly. Be sure to document the
changes when you are done.
