General information
The FE3 S2 radio remote-control receiver switch is equipped with a potential-free changeover contact that can be used for wireless switching with the FS3 series of hand-held or fixed-mounted radio transmitters. The 3 functions („On/Off“, „On“, „Off“) can be assigned to any of the transmitter buttons or one of the wired pushbutton inputs B1/B2. The „On/Off“ function (toggling on and off using a single button) is used for individual control. Using the dedicated „On“ and „Off“ functions, several receivers can be switched simultaneously (for example for group or centralized control).
The relay can be operated in switch mode or pushbutton mode (with or without timer functions). Pushbutton mode can be used for example, to control a door opener or a pushbutton dimmer.

Application
Wireless control of lamps, pushbutton dimmers, ventilators, signal emitters etc.

Operation
The „Mode“ setting selects the switch duration in minutes or seconds. The „tv“ setting selects 3 operating modes: Pushbutton, switching with timer functions, switching only (without timer function).
The „time stretch in pushbutton mode“ provides an easy way to implement a long contact time for use with a transmitter in periodic mode. When the „tv“ setting is set to „T“ then the „time stretch in pushbutton mode“ always acts in retrigger mode. If signals are no longer received from the transmitter, then the FE3 S2 switches off after the timeout.
