TWO CHANNEL MINIATURE RADIO RECEIVER
FOR REMOTE CONTROL OF 230VAC
STM-2K
Elmes STM-2K controller is designed for remote control
of two devices powered by 230VAC such as lamps, motors,
etc. Miniature size of the controller allows its installation in
electric installation boxes (wall plaster type – 60mm deep).
Wall switch, if used for wired control, may be single (if only
one channel will be used) or double (for two outputs to be
used) button. The wall switch should be a monostable type
(automatic off). The receiver includes the KEELOQ
®
code-
hopping system of Microchip Technology Inc., USA for high-
est level of security.
STM-2K receiver is compatible with all Elmes hand transmit-
ters operating at 433,92 MHz. Dedicated two channel trans-
mitters DWB100HT, DW200HT control both channels of the
receiver. Elmes 4 or 8 channel transmitters may control two
or more receivers in the following way: transmitter channels
work in pairs: channel 1 and 2 control one receiver, transmit-
ter’s channels 3 and 4, 5 and 6, 7 and 8 may control another
receivers.
STM-2K may be wired operated by two single monostable
wall switches or one double. Wired switches control the unit
the same way as the hand transmitters.
Each output of the receiver is independent and may be pro-
grammed to operate in one of the following modes:
Mode 1: (default) The receiver’s output is switched ON or
OFF each time the hand transmitter’s button is pressed (pro-
gramming procedures point 2)
Mode 2: As above, but if the output has been left in the ON
position, it will switch OFF automatically after pre-
programmed time (programming procedure point 3)

PROGRAMMING PROCEDURES
The STM-2K controller pro-
gramming is made using
PRG button with LED status
indication, as shown on the
side figure. LED slow flash-
ing speed (one per second)
indicates
correctly
performed procedure. Fast
flashing (four per second)
indicates procedures made incorrectly or procedure error.
Programming procedures, except for procedure point 2b
and 3c,d, are allowed 16 seconds to be completed. After
that time the controller automatically exits programming
mode and indicates programming error.
1. LEARNING TRANSMITTER/S to controller’s memory (up
to 112 maximum):
a) press control unit PRG switch for less than 2 sec-
onds (LED lights on). Releasing the switch LED
continues to light indicating entering programming
mode,
b) press appropriate transmitter’s button once (button
number 1 or 2 for control pair 1-2, button number 3
or 4 for control pair 3-4) - LED switches off.
c) press the same transmitter’s button second time -
end of procedure
2. MODE 1 PROGRAMMING PROCEDURE (see above):
a) press and hold PRG switch for longer than 2 and
shorter than 8 seconds. Releasing the switch sets
the LED off,
b) press shortly three times (3) programmed transmit-
ter button or wall switch.
3. MODE 2 PROGRAMMING PROCEDURE (see above):
a) press and hold PRG switch for longer than 2 and
shorter than 8 seconds. Releasing the switch sets
the LED off
b) press hand transmitter button or wall switch once –
the LED lights ON and the output sets ON,
c) when the desired time has elapsed (from 0,5 sec-
ond up to 4,5 hours) press the transmitter button or
wall switch again
d) after 2 seconds the LED starts blinking slowly con-
firming end of procedure
4. DELETING ALL TRANSMITTERS in controller’s mem-
ory. Procedure suitable in case one of transmitters is
stolen or lost: Press and hold PRG switch (LED lights)
in controller until LED starts flashing (over 8 seconds)
and then release it. The controller’s memory is now
cleared of all transmitters, however programmed modes
and timing remain unchanged. To operate the controller
by hand transmitter/s perform point 1.
5. DELETING ONE TRANSMITTER in controller’s memory.
This operation is possible under condition that the
transmitter to be deleted is in our possession. Start the
procedure as in point 1a) and follow steps by pressing
two different buttons of the transmitter. LED indicating
error in this case means the transmitter is now deleted
and will no longer operate the controller. Status of all
other transmitters learned to the controller remains un-
changed.
NOTE: procedure point 2 and 3 is possible with the wall
switch or programmed hand transmitter.
