Comunello AF 840 – 110–240 V Control Unit for 230Vac Actuators
Comunello AF 840 is an electronic control unit designed to control 230 Vac tubular actuators and motors, ideal for applications on windows, skylights, doors and windows, and building automation systems. It allows actuators to be managed via both radio control and wired buttons, offering high installation flexibility.
Equipped with an integrated 433.92 MHz radio receiver, the control unit allows the storage of up to 30 transmitters and is compatible with wired weather sensors (wind, rain and sun), which can be configured for automatic opening or closing interventions.
The AF 840 control unit
can control up to 4 230 Vac actuators, each with a maximum power of 500 W, and is compatible with 3-wire motors with limit switches. The 3 programmable wired inputs can be set for step-by-step control, deadman control, or for managing weather sensors. The opening, stop, and closing functions are fully configurable, making the system suitable for both residential and professional environments.
The Comunello AF 840 control unit is
Made in Italy and compliant with European Directives on safety and radio frequencies, with CE certification.
The control unit is
designed to connect wind, rain, and sun sensors. In the event of simultaneous interventions, the system applies a priority logic (wind → rain → sun), ensuring safe and consistent actuator behavior.
