A ductless HVAC system is controlled by light frequency signals, for example, in the infrared (IR) band. A repeater within the line-of-sight of the ductless HVAC system is used in concert with a remote thermostat. A user may operate the remote thermostat as desired, and the remote thermostat generates and broadcasts an RF signal stream responsive to the user-entry. This suitably encoded RF signal stream penetrates any wall or other opaque impediment to light frequency transmission and is received by the repeater, decoded by the repeater, re-encoded by the repeater into a signal suitable for driving an IR transmitter and broadcast as an IR beam to the receiver/interface.
Système CVC sans conduit contrôlé par des signaux de fréquence lumineuse, par exemple dans la bande infrarouge (IR). Un répéteur à portée optique du système CVC sans conduit est utilisé de concert avec un thermostat à distance. Un utilisateur peut actionner le thermostat à distance à volonté, et le thermostat génère et émet un flux de signaux radio en réponse aux commandes entrées par l'utilisateur. Le flux de signaux radio, chiffré de manière convenable, pénètre tout mur ou autre élément opaque aux ondes lumineuses et est reçu par le répéteur, qui le déchiffre et le rechiffre en un signal convenable pour commander un transmetteur IR et transmettre un faisceau IR à l'interface du récepteur.
