Version with radio receiver and humidity control: With integrated 868 MHz radio receiver and humidity control. Barrier-free product, as it switches on and off automatically via the humidity sensor. No need to set the switch-on humidity. The fan monitors the humidity level. The fan automatically ventilates at level 1 or level 2 depending on the humidity in the room. Can be switched on with a separate DS RC radio switch or a separate RLS RC control. The two speeds can be selected either on the radio switch or on the control. The speed cannot be controlled. Radio-controlled fan for the MAICOsmart exhaust air system, with a built-in 868 MHz radio receiver, based on EnOcean technology. The fan can be operated with a double rocker switch (DS RC) (no need to lay cables between the switch and the fan). The fan can be installed in a master-slave network with other ECA 150 ipro RC/RCH/KRC/KRCH (RLS RC required). A combination of ECA 150 ipro RC/RCH/KRC/ KRCH with ECA 100 ipro RC/RCH or ER 100 RC is not possible. Two power levels. Concealed intake through design cover. For ventilation. With VDE-GS mark.
