9.3 Default output via building automation – X92
To control the LMV37.4, the building automation system can predefine an output via a
bus system. The building automation system is connected to the LMV37.4 via the X92
interface.
Burner startup can take place only when contact X5-03 pin 1 is closed (load controller
ON / OFF).
Further information on connecting the building automation system to the LMV37.4 can
be found in this documentation in section Connection to superordinated systems and the
user documentation Modbus (A7541).
Minimum positioning step
To avoid unnecessary positioning steps of the actuators when the predefined target
output varies, a minimum positioning step can be set. The LMV37.4 changes the output
only if the change in target output exceeds the minimum positioning step. The minimum
positioning step only becomes active in modulating operation.
