Note!
The boiler manufacturer assumes responsibility for the correct parameterization
of the LMS14…, which must meet the requirements of the relevant standards
and directives
The connectors do not ensure total protection against false wiring. For this
reason, the connections must be checked prior to commissioning
Static charges must be avoided since they can damage the unit’s electronic
components when touched
Recommendation: Use ESD equipment!
To facilitate commissioning and fault tracing, the controller offers output and input tests.
When making these tests, the controller's inputs and outputs can be checked. To
perform the tests, switch to operating page Input/output test and go through all
available setting lines.
The current operating state can be checked via operating page State.
For detailed diagnostics of the plant, check operating pages Diagnostics heat source
and Diagnostics consumer.
