Quiet Operation
Their PTAC has been redesigned to be the quietest PTAC they've ever built. The unit's state-of-the-art design and construction provide a quiet environment, allowing guests to enjoy peaceful, sleep-filled nights.

Increased Dehumidification Capacity
Maintain lower humidity levels in rooms while cooling them without the need for expensive add-ons. As a result, guests feel more comfortable at higher temperatures, thus reducing cooling costs.

Seven-Button Touch Pad
Provides complete control to guests for in-room comfort while maintaining energy efficiency.

100% Run Tested
All units are 100% run tested at their plant in Fayetteville, TN, including leak checks during manufacturing and again prior to shipment at the warehouse.

7-5/8" Unit Front Depth
Enhance valuable room space with their slim unit front, which has a sleek 7-5/8" depth, one of the shallowest silhouettes in the industry today. In addition, to inhibit guest-tampering, the front can be secured to the chassis with a hidden screw.

Removable Condenser Shroud
Allows easy access to enable regular cleaning of coils, which is essential to maintain unit efficiency and protect the compressor for long unit life.

Easy Pull-Out Filters
Their filters are washable and easy to maintain.

Filter Dryer for Sealed System Refrigerant
Standard in all units to protect the compressor and lengthen the life of the unit by removing moisture and preventing acid formation.

Front Control
Each unit comes equipped with the DigiSmart control and energy management software. The Amana brand PTACs also have a low-voltage interface capability with a field-supplied front-desk ON/OFF switch.

Room Freeze Protection
When the unit senses temperatures of 40°F or below, the unit activates the fan motor and either the electric resistance heater or the hydronic heater.

Easy-to-Use Controls
No complex controls to confuse your guests and create phone calls for your manager. The controls are easy to read, understand, and activate. Their new 7-button control panel provides guests with complete control of the unit for their in-room comfort while maintaining overall energy efficiency.
