5.6.3 Mod. Rate Limiter, Max. O2 Correct, Remote Shutdown by Comms.
Modulation rate limiting increases/decreases the rate of change of firing rate output. The value entered is the
number of seconds the control output will take to go between 0-100%
Maximum O2 Trim Correction is the
value plus or minus that the VFD or Air Actuator can correct (+/- 10%
maximum).
Remote Shutdown by Communications allows for remote start/stop of the boiler. If this feature is enabled, the
<On Comms Failure...> setting determines what the boiler will do upon a failure of remote communications
(shut down or remain in its last state).
5.6.4 Stack Low Temp. Hold
This feature is only available with FGR. Selectable to hold FGR only (20 ppm or less) or FGR and firing rate.
“FGR Posn w/ Low Stk Temp” must be set for every combustion curve (4 maximum) and must be lower than
the FGR low fire point.
If Stack Low Temp. Hold is enabled and the stack temperature is below the “Stack Low Temp Hold” setpoint,
the boiler is allowed to modulate while the FGR actuator is forced to the “FGR Posn w/Low Stk Temp” position.
When the stack temperature rises above the setpoint for the “Delay Seconds” period, FGR will release and go
to the firing rate commanded position.
