WARNING
Safety Alert!
You MUST follow all recommendations below. Failure
to do so could result in death or serious injury. All
settings take effect immediately, including fan startup
and enabling of electric heat. Caution should be taken
to stay clear of hazardous voltages, moving parts and
electric heat elements while making adjustments to the
motor control board. If it is not practical to stay clear of
these areas during adjustment of the motor control
board, please contact Trane Global Parts for
configuration kit that allows easy powering of the
motor control board outside of the unit with a
9V battery.
CAUTION
Burn Hazard!
Failure to follow this instruction could result in the unit
overheating and becoming hot to the touch, which
could result in minor or moderate injury, and/or
equipment damage. On electric heat units, certain
parameter values are locked out to prevent overheating
of the unit. These functions will appear to be saved;
however, they will not be accepted if the Electric Heat
Protection setting is “On”. Do not change the Electric
Heat Protection setting to “Off” and make changes to
the protected settings unless you are programming an
unconfigured service replacement board to match the
unit settings on a ECM configuration label.
NOTICE
Equipment Damage!
Do not change the PWM output voltage settings as
motor damage could occur.
