If auxiliary actuator 3 is still in the ignition position (recirculation duct CLOSED), symbol
# appears for a short moment.
After entering the curve settings, auxiliary actuator 3 in flue gas recirculation (FGR)
mode temp-compensated is immediately driven to the selected point.
When selecting without DriveLowfire, the curve position can be readjusted without
having the actuator follow the position value.

When selecting auxiliary actuator 3, the display shows the current flue gas recirculation
(FGR) temperature in place of the curvepoint number.
The availability of this temperature is a means that enables you to correctly select the
functionality of flue gas recirculation (FGR).
After a change of the position of auxiliary actuator 3, the position value must not be
stored until the flue gas recirculation (FGR) temperature has really settled.
This is the only way to ensure a correct assignment of flue gas recirculation (FGR)
damper position and flue gas recirculation (FGR) temperature.
As soon as the change of the current curvepoint is stored, the current flue gas
recirculation (FGR) temperature is stored within the temperature curve.
This ensures a correct pair of values.
