The flue gas temperature sensor is connected to the O
2
module input X86 (access-
ory).
The sensor has to be configured in parameter
FlueGasTempSens
Alternatively, the flue gas temperature sensor can be used as FGR temperature
sensor (flue gas recirculation). In parameter
FGR sensor X86PtNi1000
must then be defined as FGR temperature sensor [ch. 6.15.3].

The combustion air temperature sensor is connected to the O
2
module input X87
(accessory).
The sensor has to be configured in parameter
SupAirTempSens
In conjunction with CO control, a resistance circuit board is connected to input
X87. The digital output 3 of the CO measurement amplifier is connected to the O
2
module via the resistance circuit board. The combustion air sensor then has to be
connected to input X60:3/4 [ch. 3.3.20].
