433.92 MHz BUILT-IN RADIO RECEIVER
The radio receiver can learn up to a maximum of 30 dip-switches (TXD2, TXD4, BUG2, BUG4, K-
SLIM, K-SLIM-C, T-4, T-4C) or rolling codes (BUG2R, BUG4R, K-SLIM-RP, T-4RP) which can be set
on the two channels as required.
The first channel directly commands the control board for opening the automatic device; the second
channel commands a relay for a N.O. no-voltage output contact (terminals 16 - 17, max. 24 VAC, 1 A).
The learning mode (dip-switch or rolling code) is determined by the first radio control device and re-
mains unchanged until all the codes have been cancelled.
LEARNING SYSTEM FOR RADIO CONTROL DEVICES
CH1 = OPEN/CLOSE
CH2 = 2nd channel
1_ press button CH1 briefly to associate a radio control device with the OPEN/CLOSE function;
2_ LED DL3 turns off to indicate that the code learning mode has been activated (if no code is en-
tered within 10 seconds, the board exits the programming mode);
3_ press the button of the relative radio control device;
4_ LED DL3 turns on again to indicate that the code has been memorised (if this does not happen,
wait 10 seconds and start again from point 1);
5_ to memorise codes to other radio control devices, repeat the procedure from point 1 up to a maxi-
mum of 30 transmitters;
6_ to memorise codes on the 2nd channel, repeat the procedure from point 1 using button CH2 in-
stead of CH1;
7_ to exit the learning mode without memorising a code, press button CH1 or CH2 briefly.
Note: If the maximum number of radio controls is reached (30), the LED DL3 will begin to flash
rapidly for about 3 seconds but without performing memorisation.
REMOTE PROGRAMMING BY MEANS OF T-4RP, K-SLIM-RP and BUG-R
It is also possible to carry out the remote self-learning of the new version of transmitters T-4RP, K-
SLIM-RP and BUG-R, that is without pressing the receiver's programming buttons.
It will be sufficient to have an already programmed transmitter in the receiver in order to start the
procedure of remote programming of the new transmitters, programmed by means of TAUPROG.
Activation of self-learning mode of the control unit and memorisation of the new radio control.
1. On the "old" previously memorised and functional T-4RP, K-SLIM-RP or BUG-R radio control,
press and hold the key of channel 1
2. Press the key for channel 2 three times.
3. Release the keys. The radio control led starts flashing to indicate that the self-learning mode is
enabled.
4. Press the key of the channel to be memorised.
5. At this point the control unit confirms changeover to programming mode by activating the flashing
light.
6. Press the radio control key to be memorised again. If programming is successful the flashing light
on the control unit turns off and the new radio control is ready to use.
CANCELLING CODES FROM RADIO CONTROL DEVICES
1_ keep button CH1 pressed for 3 seconds in order to cancel all the associated radio control devices;
2_ LED DL3 flashes slowly to indicate that the cancellation mode has been activated;
3_ press button CH1 again for 3 seconds;
4_ LED DL3 turns off for approx. 3 seconds and then remains steady to indicate that the code has
been cancelled;
5_ repeat the procedure from point 1 using button CH2 to cancel all the associated radio control
devices;
6_ to exit the learning mode without memorising a code, press button CH1 or CH2 briefly.
ATTENTION: TO memorise a code on a new type of remote control unit (e.g.: from dip-switch
to rolling code or viceversa) both channels must be cancelled.
