7 Internal Burner Firing Rate Controller
7 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.
7.2 Moving Screen "Actual Temperature is too high"
7.3 Changing Setpoint of Burner-Firing-Rate Controller
This is only possible when the internal firing-rate controller is active.
With active constant control:
By pressing the HAND key, the ETAMATIC would still starts as long as the maximum
temperature is not exceeded.
By pressing the HAND key again, it will change to automatic mode.
Set the firing rate value with the keys 16 and 17. In the display (left), setpoint 1 or
setpoint 2 would be shown, depending on which setpoint is chosen for terminal 50
(0 V for terminal 50 = setpoint 1, 24 V for terminal 50 = setpoint 2)
Press keys 6 and 9 simultaneously, left value blinks in display.
The setpoint can be changed with keys 4 and 5.
Press the Enter key 11 to save the new setpoint.
To end the operating function ’set firing-rate controller’ without saving the setpoint,
press keys 7 and 8 simultaneously.
