Introduction

pressed alone or in combination, are used to program some functions of the controller. The remote

display features three digits with sign and decimal point, a buzzer for signalling alarms and nine icons.
The terminal features wireless connectivity and an NFC (Near Field Communication) or Bluetooth
interface for interaction with mobile devices (on which the CAREL “Applica” app has been installed,
available on Google Play for the Android operating system).
