Internal Burner Firing Rate Controller

7.1

Purpose

The internal firing rate controller calculates the burner firing rate against a pre-defined setpoint 

value (e.g. as a function of temperature or pressure) by comparison with the actual value. This 

position will be transferred to the electronic fuel/air ratio control as a default value.

Moving Screen "Actual Temperature is too high"

7.3

7.5 How to Change the Burner-Firing-Rate Controller with the Customer Interface

7.4

Burner-Firing-Rate specified by hand

It is also possible to switch the FA1 to "Manual Control" with the terminals. By short-circuiting 

the Pt100 signal (e.g. bridge terminal 19 and 20) the burner firing rate controller is switched 

off. The fuel/air ratio controller then directly follows the input at the default firing rate input. The 

display shows LE instead of HA.

NOTICE

Only use manual control while monitoring the system.

7.5

How to Change the Burner-Firing-Rate Controller with the Customer Interface

Keep pressing the HAND key for more than 5sec., to switch the customer interface to the 

mode „set setpoints of burner firing rate controller“. This is only possible when burner firing 

rate controller is activated. At the same time, the HAND mode for manual firing rate input ends.
In the mode „setting firing rate controller“ the LED in the manual-key flashes. The lower display 

line shows the output regulator adjustment, the setpoint value and the actual value.

Active constant controller:

The Gerät can be started nevertheless by pressing the manual mode key provided that 

the maximum temperature is not exceeded.   

By pressing the manual mode key once more you switch to AUTO mode.

Press key MANUAL to move the regular firing rate input of the firing rate controller.
Press the keys 2 and 3 to variegate the burner firing rate.
Press key MANUAL again to cancel firing rate controller.

Press the key for 5 s long. Display = actual setpoint 1 or  2. 

This depends on the choice of setpoint values of terminal 50:

Terminal 50 = 0 V = setpoint value 1

Terminal 50 = 24 V = setpoint value 2
