• When the ambient temperature of the space is 2°F
below setpoint, the electric heater starts operating
and the indoor fan operates at the set fan speed.
When the setpoint +2°F is satisfied, the electric
heater stops operating. When in fan cycle mode,
the indoor fan operates at the condition of
circulating residual heat. If the fan cycle mode is not
selected, the indoor fan operates at the set fan
speed.

there is a 3-1/2 minute delay when switching
the speed of the indoor fan.
– High Speed; when the ambient temperature is
4°F higher than setpoint.
– Low Speed; when ambient temperature is less
than setpoint.
– Not Change; when the ambient temperature is
1°F to 4°F higher than setpoint.

Additional Functions
After the unit is turned ON for 30 seconds, press and
hold C C o o o o l l i i n n g g B B u u t t t t o o n n ▼ for 5 seconds to start up the
configuration mode. After entering this mode, if
adjusting the temperature compensation value by
buttons to turn to unit ON/OFF condition, the load will
be activated after 3 seconds. While if entering unit on
or off condition due to the change of the ambient
temperature, it can be activated only after quitting the
configuration mode. The following functions are
available when selecting the L L o o w w B B u u t t t t o o n n :
• Fahrenheit/Celsius Mode: press W W a a r r m m i i n n g g B B u u t t t t o o n n
▲ or C C o o o o l l i i n n g g B B u u t t t t o o n n ▼ to switch between F° or C°.
• Adjusting Cooling or Heating Values: press
W W a a r r m m i i n n g g B B u u t t t t o o n n ▲ or C C o o o o l l i i n n g g B B u u t t t t o o n n ▼ to
increase/decrease the temperature values in 1°
increments. The adjusting range of the indoor
ambient temperature compensation value is
between -6°F and 6°F (-3°C and 3°C). The
compensation temperature defaults to 0°F in either
cooling or heating mode. The unit can allocate
different compensation temperatures in cooling or
heating mode, respectively.
N N o o t t e e : : Trane recommends leaving the
compensation value set to its default of 0°F.

• Display Switchover Between Set Temperature/
Ambient Temperature Mode: press W W a a r r m m i i n n g g
B B u u t t t t o o n n ▲ or C C o o o o l l i i n n g g B B u u t t t t o o n n ▼ to set either set
temperature or ambient temperature.
• Set Temperature Display: the digital display shows
SP. After quitting configuration mode, the set
temperature displays constantly in either heating or
cooling mode.
• Ambient Temperature Display: The digital display
shows AA. After quitting configuration mode, the
ambient temperature displays constantly in either
heating or cooling mode. Under certain
circumstances, the unit displays the set
temperature for 10 second and then switches to
display ambient temperature as follows:
– Press mode button (mode button includes Cool
button and Heat button).
– Re-energize after power failure.
– Restart the unit.
– Turn on the unit after EM turns off unit.
– Adjust the set temperature using the W W a a r r m m i i n n g g
B B u u t t t t o o n n ▲ or C C o o o o l l i i n n g g B B u u t t t t o o n n ▼.
• Quitting Configuration Mode: is stopped when
pressing the mode button or if no button is pressed
within 30 seconds.

Press W W a a r r m m i i n n g g B B u u t t t t o o n n ▲ or C C o o o o l l i i n n g g B B u u t t t t o o n n ▼
simultaneously for 3 seconds under the protection for
compressor and electric heater minimum stop time or
the protection for compressor minimum operation
time, reduces the protection time.

The controller runs to the last mode set prior to a
power failure. The following settings are also retained
prior to a power failure:
• Operation mode.
• Set fan speed.
• Set temperature.
• value in minimum stop time of compressor.
• Fahrenheit/Celsius display mode.
• Cooling compensation temperature.
The unit operates in default Fan Mode when there is no
memory. Fan speed is set to high with the T-value of 0
and Fahrenheit display mode. Cooling compensation
temperature is 0 and heating compensation
temperature is 0. The default set temperature is 71°F
(22°C). The digital display shows the set temperature
under cooling and heating mode.
