PFC (Power Factor Correction) Defrost Control (HP Only) Demand DefrostThe demand defrost control measures heat pump outdoor ambient temperature with a sensor located outside the outdoor coil. A second sensor located on the outdoor coil is used to measure the coil temperature. The difference between the ambient and the colder coil temperature is the difference or delta-T measurement. This delta-T measurement is representative of the operating state and relative capacity of the heat pump system. By measuring the change in delta-T, we can determine the need for defrost. The coil sensor also serves to sense outdoor coil temperature for termination of the defrost cycle. Fault Identification A fault condition is indicated by the CDA connected to the control board inside the heat pump control box. Defrost Enabled Demand Defrost is enabled with the following inputs to the drive:: • Outdoor ambient temperature sensor (ODS-B) reporting an outdoor temperature at or below 52' F. • Coil temperature sensor (CBS) reporting a coil temperature at or below 32' F. • Heat/Cool Demand (HCD) from the communicating comfort control for at least two minutes or more. Defrost Initiation The calculated temperature difference between the outdoor temperature sensor and the coil temperature sensor is called Delta T. Defrost can occur once the current Delta T exceeds the Delta T initiate value.. This adaptive logic assures a complete defrost for a range of outdoor temperatures. Note: There are three (3) defrost termination temperature selections available in the Configure Menu. Factory is set to 47°F, medium is 53°F, and high is 60-F.
