Lennox 10U44 ECM Module Kit

The Lennox 10U44 is a 5.0 ECM Module Kit that is used to replace Lennox HVAC systems that are fitted with Electronically Commutated Motor. An ECM motor is a blower motor which is variable speed and is more efficient than other motors. The module kit controls this variable speed operation to maintain airflow in the home at an optimal level. It can increase comfort by maintaining schedule temperatures, and might even save energy by operating a blower motor at lower speeds.
