Aaon ASM08077 Motor Speed Control R-448A This is a programmed ECM

This is a programmed ECM blower motor

Simplified Installation: Standard 5/16-inch flat shaft allows for quick transfer of the existing squirrel cage or centrifugal blower wheel

Critical Safety Protection: Pre-set to release at 450 PSI to safeguard compressors and heat exchangers from over-pressurization

replacing a compromised harness is standard procedure to restore reliable communication between the control board and field-installed sensors

this motor is strictly rated for 24V AC operation
