Switching

Switching off indoor fan during defrost (for units with a single compressor) This module provides the option of stopping the indoor fan during the defrost cycle. The option is only for cases where it is not possible to fit an auxiliary electric heater. - With the JP-19 bridge in place (as sent out from the factory) the indoor fan will continue operating during defrost. - With the JP-19 bridge open (jobsite modification) the indoor fan is switched off.
