installation. If more serious faults or problems arise the installer should contact a qualified technician.

Problem Actions

N Ensure that connections to all radiators have been made correctly

and that each radiator's mains supply is connected and switched on.

Transmitter indicates "radiator fault":

N Ensure that connections to all radiators have been made correctly

and that each radiator's mains supply is connected and switched on.

N Examine the radiator LEDs.

Transmitter does not synchronise

automatically to the maximum number of

channels in DCN:

N Ensure that the number of channels is set to automatic (using

menu item 4B).

N Check whether a DCN interface module of version 01.05 or higher

is used.

one or both IRED panels of a radiator:

N IRED panel malfunctions and the radiator should be replaced.

Infra red receiver fails to function properly:

sufficient capacity and whether they are inserted with the correct

polarity.

N If a battery pack is used, ensure that the battery pack is fully

charged.

N Ensure that the headphone is connected properly.

N Switch the receiver on and check whether the display indicates a

channel.

N Set the transmitter in test mode and check whether the test tone is

audible on the receiver.

If all receivers do not work properly at that spot, check the

coverage of the system (see section 1.6).

The charging indicator LED on the receiver

is blinking:

N Check that the charging unit is used under the specified working

conditions (see technical data).

N Check that the receiver contains a battery pack which is connected

correctly.

N Ensure that the receiver is at room temperature and re-insert the

receiver in the charging unit.

N If the charging indicator starts blinking again, replace the battery

pack and check whether the problem is resolved.
