B) Using Several Transmitters; C) Timer Functions (2-Channel Operation) - Conrad Electronic FS20 S4 Operating Instructions Manual

b) Using several transmitters

In the delivery state each transmitter in the FS20 wireless control system
has its own, randomly set house code.
If you want to jointly control one or several receivers via different transmit-
ters, you first need to coordinate the transmitters' house codes.

The same house code must be set for each transmitter, as
described in section 11.
This must be set before programming the receivers for the
first time, as the associated house code is also sent to the
receiver during this procedure.
The transmitters' channels are already set to the same addresses and only
need to be changed, if required (see sections 5 and 6).

c) Timer functions (2-channel operation)

In order to program a receiver's timer function you must simultaneously
press the button combination that has been assigned to the receiver for
between 1 and 5 seconds (1 sec to 5 sec) on the hand-held transmitter.

This button combination is used to start as well as to stop the
programming of the timer. For information on how to program
the timer, see the instructions in the receiver's user manual.
