Unico Modular Blower, 3-3.5 Ton, S.M.A.R.T. Control, Variable Speed EC Motor, 208/230V (M3642BL1-EC2)

Unico High Velocity HVAC Horizontal Modular Blower - M3642

The E.C. motor is the heart of the Unico air handler blower series. The variable-speed fan motor continually adjusts air volume and blower speed to provide a perfectly-calibrated flow of comfortable heating and cooling at greatly reduced sound levels.

It features advanced manufacturing and design characteristics for elevated energy efficiency, indoor comfort, and maximum reliability.

Key features of the E.C. motor:

• At low speeds the new E.C. motor is up to two decibels quieter
• The E.C. motor is up to 30 % more efficient than our standard motor
• Can be used to upgrade existing air handlers manufactured after 2003

S.M.A.R.T. Control Board (SCB)

The S.M.A.R.T. Control Board is the brains of the new air handler series. Combined with the E.C. motor, it provides the highest level of indoor comfort that a consumer demands.

Features of the S.C.B:

• The ability to intelligently manage both air volume and motor speed according to the needs of the thermostat and or zoning needs
• Two options to set airflow
• Diagnostic feedback
• An enhanced soft start and soft stop enhances comfort

Program Software Enables Easy Service and Maintenance

1. Download software and connect to a laptop or notebook to adjust the program via USB cable
2. On board, switch selectable pre-programmed settings

Precise Airflow Control

The E.C. motor and S.C.B provide premium performance that is an advancement beyond the industry standard. Our advanced software gives you unrivaled control of the E.C. motor, resulting in consistent air volume and pressure cross a wide range of operating conditions.

When compared to the industry, most E.C. motors are factory programmed for specific airflow settings and do not allow changes which limits your ability to provide a customized heating and cooling solution.
