This message is received when the infrared signal is not one of the
known formats which requires too many bytes to encode. Such
infrared signals cannot be learned by the UCM
Problems with Learned IR Codes
Sometimes, the infrared signals can be captured and encoded
successful, but when transmitted through an Infrared LED
connected to an output, it does not activate the device. The possible
causes and solutions are
The UCM05 may encode the signal incorrectly if the remote control
is not pointed correctly at the receivers. The remote control should
be pointed directly at the infrared receivers U8 and U9 at a distance
of 5 to 10 cm away. The remote control should not be too close to
the receivers because the actual location of the transmitter LED
behind the infrared lens is not known. The transmitter may not be
at the center of the lens so it may be pointing at the wrong angle.
Positioning the remote control 5 to 10 cm away will reduce the
effect of the uncertainty of the location of the transmitter.
The infrared code is sent to any output using Action 129 (or using
the Response Wizard in Comfigurator). Check that the correct
infrared code number is sent to the designated output. A useful
diagnostic tool is to plug in a Test Lamp terminal Block into the
This consists of two 12V DC lamps which light up when the output is
turned on. When an infrared signal is sent to the output, the lamp
will briefly blink. It should not be permanently turned on. This
shows that the output is receiving an infrared signal, but it does not
mean that the IR signal is the correct one. A useful tool in any
installation where infrared transmission is needed is a long length of
wire, about 30 meters with an IRM01 transmitter on one end and a
terminal block on the other. This can be quickly connected to any
output and the transmitter pointed at the appliance to operate it.
This will show if the programming is correct.
