Feature●Microprocessor-based control for detecting ice build-up and defrosting the outdoor coil in heat pump systems●Demand defrost algorithm “self-calibrated” to the heat pump system●Features include short-cycle protection, noise reduction and LED diagnostic display●Includes ambient and coil temperature sensors●Plastic standoff mountingDescription
The Emerson 47D43-811 demand defrost control is a microprocessor-based control that detects the ice build-up on the outdoor coil in heat pump systems and reverses the direction of the refrigerant glow to defrost the coil. This control features LED diagnostic display and dipswitch selectable defrost termination temperatures - 50/60/70/80 degree F.
