Application
This is the outdoor half of a split-system heat pump. To function as a complete HVAC system, it must be paired with a compatible indoor coil or air handler and appropriate controls/thermostat.
Heat pumps both cool in warm weather and provide heat in mild/cool conditions by reversing the refrigeration cycle — making them a combined cooling/heating solution. device.report
