Sets the mode of the FGR hold for the Aux 3 actuator. Seven seperate operating modes exist.
These are:
1) Aux3onCurve- Function deactivated and Aux 3 actuator always operates on its
programmed curve.
2) time - Aux 3 actuator stays at ignition position until DelayTimeFGR Gas(Oil) timer expires.
3) temperature - Aux 3 actuator stays at ignition position until ThresholdFGR Gas(Oil)
temperature is reached.
4) temp.contr. - Position of Aux 3 actuator is based on flue temp, Factor FGR Gas(Oil) , and
the programmed curve for the Aux 3 actuator (LMV52.4 only).
5) TCautoDeact - same as Temp.contr but automatically deactivates if there is a fault with the
flue gas sensor (LMV52.4 only).
6) deactMinpos - after ignition position, Aux 3 actuator is held closed (LMV52.4 only).
7) auto deact - do not select this option. It is displayed if the FGR hold was deactivated due
to a sensor issue (LMV52.4 only).

hresholdFGR Gas(Oil) (S) 752 F 32-1562 F
This sets the temperature that must be achieved to release the Aux 3 actuator to modulate.
Only has an effect if parameter FGR-Mode is set to "temperature".
x x
DelaytimeFGR Gas(Oil) (S) 300s 0-63min
This sets the time that must elapse before the Aux 3 actuator is released to modulate. Only
has an effect if parameter FGR-Mode is set to "time".
x x
Factor FGR Gas(Oil) (S) 100% 10-100%
Adjustment of calculated temperature dependent position of the Aux 3 actuator. An
adjustment of less than 100% reduces the position of the Aux 3 actuator. 100% means no
adjustment. Factor only has an effect when FGR temperature is different than when ratio
curves were commissioned.
