ECM Overview and Setup
UV-SVN03F-EN 61
Configuration Settings of the ECM Engine
Board
Note: The engine board functions and unit specific
settings are summarized on the ECM engine
configuration label affixed to the back side of the
control panel low voltage lid, on every unit.
The following table lists the parameter names and typical
settings of the ECM engine board, for reference only.
Additional Notes:
1. This list is applicable only to Fan-coil and Force-Flo
products.
2. Do not change the electric heat protection settings if
your unit has electric heat.
3. If the format setting for rpm va
lues are not correct (i.e.,
not four-digit: XXXX), please check the operation mode
of the ECM engine board
 and  and motor
signal output format  and .
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 ECM engine board. If it is not practical to stay
clear of these areas during adjustment of the ECM
engine board, please contact Trane Global Parts for
configuration kit that allows easy powering of the
engine board outside of the unit with a 9V battery.
The adapter boards contain high voltage. Configuration
adjustments to the ECM engine board should be made
through the SMALLER of the two low-voltage lids on
the front of the control panel, through the low-voltage
insulation/shielding.
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.
NOTICE:
Equipment Damage!
Do not change the PWM output voltage settings as
motor damage could occur.
