The Anderic RRDYS01 is a direct replacement for the original 966538 remote control, designed for the Dyson AM09 Hot+Cool Jet Focus fan heater. It provides instant access to heating and cooling modes, airflow speed, oscillation, and Jet Focus control without requiring any programming. This IR-only remote is compatible exclusively with AM09 models and will not operate Dyson cool-only fans, purifiers, or humidifiers. Simply use it with your AM09 for full remote functionality.
