Extreme 3500tiR – Self Contained

This product is intended for through-the-wall installations. It is an “upgrade” to the Extreme ti because it uses the KDT Plus remote controller and thermostat. The duct plenums for the evaporator and condenser can be purchased separately. 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.

NOTE: If this unit will be installed through an exterior wall, you will need to purchase an exterior housing to protect the unit. If this unit will be installed through an interior wall, the hot air exhaust may be redirected to another location using the condenser ducting plenum kit.
