The DigiSmartâ„¢ digital control board is specially designed for Amana packaged terminal air conditioner (PTAC) units. Its energy management system (EMS) programs can connect to wired or radio frequency-based EMS systems. The company states that the DigiSmart has a large, easy-to-read LED display with one-button activation designed for easy use by hotel and motel guests. The guests can turn up the temperature or turn it down, degree by degree, in Fahrenheit or Celsius, the manufacturer says. The PTAC's operational status can be reviewed for maintenance, such as when to clean the filter or coils. The digital control board can be purchased separately and retrofitted into existing PTAC units.
