5. Operating Instructions

The Amana HEH073K25DXXX PTAC unit is controlled exclusively by an external thermostat. Once the unit is properly installed and connected to an external thermostat, you can manage its operation.

5.1 Basic Operation via External Thermostat

• Power On/Off: Use the external thermostat to turn the unit on or off.
• Mode Selection: Select desired operating mode (Cool, Heat, Fan Only) on your external thermostat. The unit will respond accordingly.
• Temperature Setting: Adjust the desired room temperature using the external thermostat's controls.
• Fan Speed: If supported by your external thermostat, adjust the fan speed (e.g., Low, Medium, High, Auto).

5.2 Smart Door Economizer Function

The integrated Smart Door Economizer feature allows the unit to utilize favorable outdoor conditions to cool the room. When the outside air is cool and dry enough, the unit can bring in this air to maintain comfort, thereby reducing the need for mechanical cooling and saving energy. This function operates automatically based on programmed settings or external thermostat commands, if applicable.
