A control adapter for fastening on a HVAC device includes a wireless communication interface for communicating control signals between a remote control device and the control adapter. A wireless near-field communication interface communicates control signals between the control adapter and the HVAC device. A control circuit converts the control signals received from the wireless communications interface into the control signals of the wireless near-field communication interface and converts the control signals received from the wireless near-field communication interface into control signals of the wireless communication interface.
