HVAC Products 18 Addendum 4: LMV52... with O2 trim control and O2 module 11.12.2008
O2 module
In comparison with the LMV51... system, the extra components to be connected with
the LMV52… system are the O
2
module and the O
2
sensor QGO... and, optionally, the
combustion air and flue gas temperature sensors. The O
2
module is to be connected to
the basic unit via the CAN bus. The O
2
module must be located in the vicinity of the
QGO... (< 10 m), aimed at keeping interference on the sensitive detector lines as low
as possible. For sensor heating, the O
2
module requires a separate mains connection
facility.
