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.
