simulate hysteresis of a real bi-metallic disc temperature
switch.
• When combined with the CSTI adapter board, the bi-
metallic disc temperature switch emulation and the electric
heat lockout function will work when the switches are set
correctly.

Configurations

Every Trane unit with ECM motors will have modules
specifically configured at the factory for the operation of that
unit. The motor control board configuration label is affixed to
the low-voltage access lid on the outside of the control panel.
The VelociTach™ motor control board label may be on the
back-side of the low voltage access lid, depending on the unit
configuration.
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

WARNING
Safety Alert!
You MUST follow all Instructions below. Failure to do so
could result in death or serious injury. All settings take
effect immediately, including fan start-up 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!
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. 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.
