Specification outline
The difference between the suction temperature and
AUTO
the discharge temperature and suction temperature
set by the remote controller automatically switches
unit type
between cooling and heating operations. If both
(TF type)
conditions 1 and 2 are satisfied, the thermostat will
be turned on.
※ For TF type, TA = Suction air temperature.

temperature. Since
there is no function
of the room
temperature
control, the room
temperature and
the outlet
temperature are

not controlled even
+6 ˚F
if this setting is
changed.
TF : Temperature of

• If the thermostat
does not turn on
even in the
