Design and Functions
NOTICE
When running oil-solely burning applications, the function ’Oil pressure > min’ is aligned with
X05. When running oil/gas burning applications (BT340 in combination with DFM300), the
function ’Gas > min’ is aligned with X05.
Put in oil/gas applications, the pressure monitoring for ’Oil pressure > min.’ in the oil safety
interlock chain (SIC).

Terminal assignment BT335 - Connection example
NOTICE
The effects of a failure of relay K1 at output 26 of the BT335 must be evaluated taking into
account the application in which the BT335 is used. A suitable relay must be used according
to the results of the evaluation and the safety requirements of the system.
The relay coil must be suitable for the supply voltage of the BT300 (230 VAC or 120 VAC).
