Information concerning the currently attached O2 sensor.
U
Software version of the O2 module.
Sets the mode of the FGR hold for the Aux 3 actuator.
This can be time or temperature based. The Aux 3 actuator can be made to release to its normal fuel-air
ratio curve position after a certain length of time, or after a certain temperature (typically stack temperature)
is reached. This serves to let the boiler to warm before admitting FGR to the burner. This will not stop the
S
other actuators (fuel, air, aux 1, etc...) from driving to whatever load is defined by the load controller.
Range = deactivated, time, temperature Def = deactivated
Selection of the temperature sensor if the temperature based FGR hold is used.
Options are a Pt1000 connected to the PLL module (O2 trim module) or a Pt1000, Ni 1000 connected
directly to the load controller. Def = PLL_Pt1000
U The actual temperature read by the selected sensor can be viewed at this parameter U The actual temperature read by the selected sensor can be viewed at this parameter.
For gas firing, this sets the temperature that must be achieved to release the Aux 3 actuator to modulate.
Has no effect if parameter "FGR-Mode" is set to time.
Range = 32 to 1562 F Def = 752F Typ = 320F
For gas firing, this sets the time that must elapse before the Aux 3 actuator is released to modulate.
Has no effect if parameter "FGR-Mode" is set to temperature.
Range = 0 to 63 minutes. Def = 300 sec Typ = 30 min
S
For oil firing, this sets the temperature that must be achieved to release the Aux 3 actuator to modulate. Has
no effect if parameter "FGR-Mode" is set to time.
Range = 32 to 1562 F Def = 752 F Typ =320 F
For oil firing, this sets the time that must elapse before the Aux 3 actuator is released to modulate.
Has no effect if parameter "FGR-Mode" is set to temperature.
Range = 0 to 63 minutes. Def = 300 seconds. Typ = 30 minutes
