ERROR HANDLING
From this parameter window it is possible to enable the sending of messages to the
KNX bus to report the occurrence of errors, including both internal errors regarding the
communication between KLIC-DI and the A/C unit, and external errors affecting the
A/C unit itself.
Figure 11.

: when enabled, a new communication object shows up,
"
Internal Error: Communication

it is "0", there is no error.
Note: If an internal error communication is active, the next actions are
recommended:
1. If there is a remote wired control in the installation, check whether it
reports any error.
2. Verify that KLIC-DI is properly connected to the A/C unit.
3. Verify that control configuration is correct. Check that the device and
the remote wired control are not both configured as slaves.

External errors
: when enabled, two new communication objects show up:
"
External Error
" (1-Bit) and "

second object indicates the specific code that identifies the error (please refer
