Display and diagnostics

Transmission of operating states, fault status messages and detailed service information
via:
BCI communication via integrated RJ11 jack to the AZL2, or via additional OCI410
interface to ACS410 PC software
Communication / parameterization
The AZL2 offers ease of operation, parameterization and targeted diagnostics via
features menu-driven operation. When making diagnostics, the display shows operating
states, the type of error and startup meter reading. Passwords protect the different
parameter levels of the burner / boiler manufacturer and heating engineer against
unauthorized access.
ACS410 PC software enabled a simple operation, comfortable readout of settings and
operating states, the parameterization, trend recording and targeted diagnostic of
LMV27.
For this purpose, the OCI410 interface for communication with the LMV27 is connected
to the PC. This interface is available separately and is connected to the integrated RJ11
jack.
