Trane UniTrane User Manual

ECM Overview and Setup
76 UNT-SVX07J-EN
The serial number of each unit and the custom
configuration settings specific to that unit will be printed
on the label for convenient matching of labels/settings to
specific units. Programming a unit with the settings from
another unit will result in abnormal operation. The label
contains four important sections:
• How to enter the configuration menu
• The description and meaning of the error codes
• The description and meaning of the status display
• The parameter names and values specific to that unit
Note: This label is provided for reference only, as an
example, and should not be used to configure the
unit.
Motor Control Board Settings
Note: The motor control board functions and unit specific
settings are summarized on the motor control
board configuration label affixed to the back side of
the control panel low voltage lid, on every unit.
Table 38 lists the parameter names and typical settings of
the motor control board, for reference only.
Do not change the electric heat protection settings if your
unit has electric heat.
If the format setting for rpm values are not correct (i.e., not
four-digit: XXXX), please check the operation mode of the
motor control board
mod1 and mod 2 and motor signal
output format
SIG1 and SIG2.
Note: The following notes are provided for reference
only, and the motor control board label must be
used as the ultimate guide for setting up an motor
control board on specific units.

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.
