Dehumidification
* If a system is a heat pump connected legacy, then a DFT will show on the
board in 2 instances.
1. If the heat pump calls for a defrost, Y and a W will be energized resulting
in a DFT code on the air-handler display.
2. If the heat pump calls for auxiliary heat, Y and a W will be energized
resulting in a DFT code on the air-handler display.
