Self test is made at 23-intervals. Test requires constant O
2
level, for e.g. after pre-
purge or on steady load. If constant O
2
level is not reached within 24 hours, burner
control locks down operation load to reach constant O
2
level for next test. If burner is in
stand by mode, test is made during next burner start-up.
Flue gases containing aggressive acids may strongly shorten oxygen
sensor durability.
O

module can be connected with burner combustion air and flue gas temperature
sensors. If sensors are connected, warning is displayed when flue gas temperature is
too high, and combustion efficiency will be calculated and displayed.
Check that oxygen value and sensor temperature, heating efficiency
and resistance values are displayed. If temperature sensors are
connected and activated, values should be displayed.
