Integrated IR receiver

Integrated IR receiver allows the controller to act as a receiver for a handheld remote. For indoor units which already have a built-in IR receiver this improves the handheld remote coverage range. For indoor units without a built-in IR receiver, it removes the expense and time of installing a dedicated IR receiver accessory.

Set Back function

Even when the AC is switched off, the set back function enables it to automatically activate if the room temperature reaches a certain level. In heating mode it can prevent the room temperature falling too low, and in cooling mode can prevent the room from over heating.
