Wall-mounted radio transmitters for the control of awnings and shutters. Available in versions with 1 to 6 channels, for the control of up to 6 automations in single, group, or multi-group mode, and also with separate activation of the sun sensor. 433MHz, rolling code with self-learning function. Simple groups management: option of memorising a single transmitter for several awnings, blinds or shutters to create groups. This function is available for the tubular motors in the series Era Mat and Era Fit, with incorporated receiver. Powered by two 1.5 Vdc AAA commercial batteries. For sun sensor management: On versions W1S and W6S, the buttons Sun On and Sun Off enable activation and deactivation of communication with the sun sensors integrated in the installation (Nemo WSCT, Nemo SCT, Volo-S). Also, thanks to the two led indicators associated with the control buttons "Sun for You", the user can always check the status (on/off) of the sun sensor for the selected group/automation.
