RADIO MODULE (OPTIONAL)
To operate the control board via radio remote control, a radio
module must first be installed in slots CN1/CN2. The following
modules are available: 801221 (433.92 MHz), 801429 (27.145
MHz), 207542 (315.15 MHz China)
PROGRAM TX4UNI
Insert radio module on designated pins, if not pre-installed.
The receiver has two channels CH1 and CH2.
The respective LEDs CH1 and CH2 are assigned to these two channels.
Receiving a signal from a programmed remote control button, CH1
opens both wings. Receiving a signal from another programmed remote
control button, CH2 opens only one wing (pedestrian mode).
Program the remote control using CH1

(do not press yet).
2. Press button CH1. LED LEARN1 comes on for approx 10 seconds.
3. Within these 10 seconds:
- press now the previously selected button of the remote control.
- as control board and remote control are now going to adjust a
matching code, the button on the remote control must be possibly
pressed a second or third time.
- Once LED LEARNTIMER and then all other LED have flashed
proceed with step 4.
4. Press one of the remaining 3 buttons of the remote control to end
programming using CH1.

control) to go out. Then start again with step 1.
Up to 128 remote controls can be programmed likewise.
Program the remote control using button CH2
(opens only one wing) :
1. Press and hold left and right button of the remote control

3. Within these 10 seconds:
- press now the newly selected button of the remote control.
- as control board and remote control are now going to adjust a
matching code, the button on the remote control must be possibly
pressed a second or third time.
