E15 Defrost Control – Product Overview
The Type E15 Defrost Control is designed to manage frost removal from the outdoor coil of central systems and window unit heat pumps. It features a temperature-sensing bulb with capillary tubing, a timer motor, and a switch mechanism. The remote bulb monitors the outdoor coil temperature, while the timer permits defrost cycles only at pre-set intervals. The internal switch then activates the system’s defrost functions accordingly.
