Internal Burner Firing-rate Controller

7.11

Start-up Sequence

The firing-rate controller has a startup circuit, in order to slow down the burner's start firing-
rate. The startup circuit is run during each new burner start. The internal firing-rate is held at
a value (P 792 adjustable by the user, for as long as the boiler is cold (actual value is below a
user-adjustable limit, P 791). If the controller’s actual value is equal to or larger than the pa-
rameterised startup maximum temperature, this startup circuit is canceled.
In order to prevent a situation where an excessively large demand on system output, the boiler
temperature necessary to cancel the startup circuit is not reached, a startup timer is also trig-
gered in parallel (this timer can also be adjusted by the operator, P 793). Once the internal
firing-rate reaches the parameterised startup firing-rate, the output is increased linearly step-
wise up to the maximum firing-rate. The slope of this linear increase is calculated from the pa-
rameterised startup time.

C or bar (xx.x)
Set the minimum value for the first controller setpoint
(active if input "set point switching" = 0) (weather guided
controller) in this parameter. If the firing rate controller is
configured as a constant controller, the set point is set
here.

1.Selection switch: firing-rate value



2.Display: controller setpoint, controller actual value,



firing-rate setpoint, internal firing-rate



3.Channel key 3 down and channel key 4 up at the



same time



4.Controller setpoint starts to flash and the setpoint can



be changed with channel key 2



5.Do not save value: channel 3 up and channel 4 down



at the same time or switch off burner



6.Save value: save the setpoint to the minimum value



parameter with the Enter key (in P 796 / P 798



depending on the setpoint switching input)
Saving is only possible with constant controller.



With control by atmospheric conditions you may set the
firing-rate controller setpoint value default manually
Activation of the controller setpoint modification is dis-
abled when operating mode is OFF. You may not trigger
the burner start by shifting the switching point.

point Switching of the Firing-rate Controller"
