The DigiDoor is a combination door switch and room motion sensor powered by 2 AA batteries that are included in the kit.Once wirelessly linked to an Amana brand DigiSmart PTAC, the DigiDoor monitors room occupancy and automatically activates the Energy Management System (EMS) temperature set-back function.You can further refine your EMS programming by configuring the DigiSmart with up to 100,000 EMS set-back combinations, either through the DigiSmart touch-pad or wirelessly through the optional DigiTenna DT01A and DP01A Gateway.The DigiTenna (DT01A) is required for the DigiDoor to communicate to the DigiSmart PTAC.
