The ECM motor includes “soft start” and “ramp down” features. The soft start feature is a gentle increase of motor rpm at blower
start up. This creates a much quieter blower start cycle.
The ramp down feature allows the blower to slowly decrease rpm to a full stop at the end of each blower cycle. This creates a
much quieter end to each blower cycle and adds overall unit efciency.
The ramp down feature may be eliminated during an ESD (Emergency Shut Down) situation when using a DXM unit controller.
A DPDT relay is required to break the line voltage to the ECM motor during ESD. This relay can be wired as shown below to
eliminate the ramp down (and operation) of the ECM blower motor.
Cooling Settings: The cooling setting determines the cooling (normal) CFM for all units with ECM motor. Cooling (normal) setting
is used when the unit is not in dehumidication mode. Tap 1 is the lowest CFM setting, while tap 4 is the highest CFM setting. To
avoid air coil freeze-up, tap 1 may not be used if the dehumidication mode is selected. Consult submittal data or specications
catalog for the specic unit series and model to correlate speed tap setting to airow in CFM.
Heating Settings: The heating setting determines the heating CFM for Tranquility
®
30 (TT) and Tranquility
®
20 (TS) units. Tap 1 is
the lowest CFM setting, while tap 4 is the highest CFM setting. Consult submittal data or specications catalog for the specic
unit series and model to correlate speed tap setting to airow in CFM.
Auxiliary/Emergency Heat Settings: The auxiliary/emergency heat setting determines the CFM when the unit is in auxiliary heat or
emergency heat mode. This setting is used for residential units with internal electric heat. When auxiliary electric heat is energized
(i.e. compressor and electric heat), the greater of the auxiliary/emergency or heating setting will be used. A “G” (fan) signal must
be present from the thermostat for electric heat to operate. Consult the submittal data or specications catalog for the specic
unit series and model to correlate speed tap setting to airow in CFM.
CFM Adjust Settings: The CFM adjust setting allows four selections. The NORM setting is the factory default position. The + or –
settings adjust the airow by +/- 5%. The +/- settings are used to “ne tune” airow adjustments. The TEST setting runs the ECM
motor at 400 cfm/ton, which causes the motor to operate like a standard PSC motor, and disables the CFM counter.
