Pro-source CED4478 Fan Speed Control 115V 1.5A

Product Description

The PRO-SOURCE CED4478 is a fan speed control designed for multi-fan HVAC and ventilation applications. It operates at 115 volts with a 1.5-amp rating and is built to regulate airflow across systems running 6 to 10 fans simultaneously. The unit is compact, measuring 2 inches in height, 2 inches in width, and 2 inches in length, making it suitable for installation in tight electrical enclosures or control panels. HVAC technicians and electricians install this control as part of air-handling, ventilation, or fan coil systems where variable speed adjustment is required to meet airflow demands.

This fan speed control is suited for residential and light commercial ventilation systems that run multiple fans from a single control point. Typical applications include multi-fan exhaust systems, air handlers, and fan coil units where coordinated speed regulation across 6 to 10 fans is necessary. Its standard 115-volt input makes it compatible with common single-phase electrical systems found in most domestic HVAC and ventilation installations.

Installation Notes

Installation should be performed by a licensed electrician or qualified HVAC technician. De-energize the circuit and verify voltage absence with a meter before handling any wiring or removing the existing control. Follow applicable NEC requirements for control wiring and enclosure ratings. Confirm the total connected fan load does not exceed the 1.5-amp rating of this control before energizing.
