General information
The FE3 S2 radio remote-control receiver switch is equipped with two potential-free closing contacts 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, motors (roller shutters, blinds, gateways, ventilators ...).

Function
In serial switch operation mode the relays can be operated in “push-button mode” or in “switching mode”, with or without time monitoring. In motor operating modes M1 and M2, the relays are interlocked.
In M1 mode (1-button motor control) one transmitter button generates the switching sequence “Up, Stop, Down, Stop”.
In M2 mode (2-button motor control) two transmitter buttons (one for each direction) generate the switching sequence „Up, Stop“ and „Down, Stop“ respectively.
In mode J2 (2-button blind control), the blades‘ angle can be exactly adjusted by the „short-push mode“ (short push <1s), or set to a defined angle after moving up or down.
Using the dedicated „On“ and „Off“ functions, several receivers can be switched simultaneously (for example for group or centralized control).
The „time stretch in pushbutton mode“ (in modes SN and SNs) provides an easy way to implement a long contact time for use with a transmitter in periodic mode. The run-time set here is used to bridge the time until an new transmitter signal retriggers a new switch period. If signals are no longer received from the transmitter, then the FE3 D2 switches off after the timeout. (eg used for motion detectors, heating thermostats, etc.).
