The ECM fan is controlled by an interface board that converts thermostat inputs and eld selectable CFM settings to signals used
by the ECM motor controller. Units manufactured after July 2005 have version II (P/N 17B0019N01). Fan speeds are selected with
a nine position DIP switch for version II. To take full advantage of the ECM motor features, a multi-stage thermostat should be
used (2-stage heat/2-stage cool or 3-stage heat/2-stage cool).
HFC-410A packaged units built after May 2009 have ECM controller version III (P/N 17B0034N01). This controller includes logic
and a relay to control the HWG functions.
Note: Power must be off to the unit for at least three seconds before the ECM motor will recognize a speed change. The
motor will recognize a change in the CFM Adjust or dehumidication mode settings while the unit is powered.
There are four different airow settings from lowest airow rate (speed tap 1) to the highest airow rate (speed tap 4). The charts
below indicate settings for both versions of the ECM interface board, followed by detailed information for each setting.
