    Press key 11 "ENTER“ to confirm. Take the correction into account during later programming. The correction actuator must be able to operate without the ETAMATIC reaching the end-stop (0 or 999 or limit stop values). If the correction actuator cannot be driven all the way as required because a channel has reached the range limit determined during pre-ventilation, the burner's output is increased or decreased until the actuator can be driven all the way.

    To leave the manual load pre-setting press one of the keys 4 to 9. You also may switch the ETAMATIC to "Manual Control" with the terminals. By short-circuiting the PT 100 signal (e.g. switch on terminal 19 and 20) the load control unit is switched off. The compound then directly follows the default of the signal on the load default input.

  • Page 60: Control Range

    Internal Burner Firing-rate Controller 7.16 Control Range The control range lies around the setpoint. The content of the "Burner on" parameter is sub- tracted from the setpoint value to form the switch-on value. The value of the "Upper control range" parameter (P 803) is added to the setpoint value to form the upper limit of the control range.

  • Page 61: Control Mode

    Control Mode Control Mode The firing-rate controller endeavours to bring the actual value into line with the setpoint value. In so doing, a direct correlation is assumed between the internal firing-rate and the boiler tem- perature, i.e. the greater the internal firing-rate, the faster the boiler temperature rises. Should the curves be programmed differently, the firing-rate controller will not function....

    8.2.3 Standby Standby mode In this mode the ETAMATIC enables a switchback to ignition burner mode. The burner re- starts without pre-ventilation. You can activate „standby mode“, if the internal firing-rate controller is active or if an external input or output command can be connected to LSB module or fieldbus (see parameter 812, level 4).
  • Page 68 Otherwise You have to use one flame detector for the main flame and one for the pilot flame. If the "Burner on" signal will be removed during stand-by mode, the ETAMATIC switches off.
