Extreme tiR fully ducted (FD): This product is intended for fully ducted installations. Fully ducted units are for customers who don’t want to see their unit in the cellar. The duct plenums for the evaporator and condenser will be included with your purchase. This unit also comes with a KDT Plus remote controller and thermostat. The controller can be mounted outside the cellar, allowing you to monitor your cellar temperature without needing to enter. The controller can be mounted up to 50 feet away from the Extreme unit.
