Fuel selection
The WOOD option is recommended only for boilers with an additional grate when burning wood. In this option,
the burner does not work. Only the fan is used which works in a comparable manner to wood-fired boilers. The
PELLET option activates all the functions of the regulator and the burner.
Type of work
Select the type of operation: Burning-feeding or Burning-stopping. For full automatic operation of the burner,
we recommend setting the burning-stopping option.
Burning-stopping enables fully automatic operation of the burner which is turned on and off by the regulator
according to the actual heat demand. This type of operation is recommended in the summer. In the WINTER
mode, adjust the FLAME FEEDING TIME parameter to limit the number of burner turn-ons. In the menu (flame
feeding mode) set the time for which the regulator is in feeding mode (after reaching a desired temperature
value) waiting for the boiler to cool off. If this does not happen, the regulator will automatically turn on the
stopping function. This option will reduce electricity consumption due to a lower number of ignition-operation-
stopping cycles. When the boiler has a lower temperature than it is required, the self-ignition function will be
turned on automatically.
Note: Setting the FLAME FEEDING TIME to zero will immediately stop the burner after heating the boiler to the
set temperature.
The feeding function operation is recommended in the winter period. For this setting, the burner does
not stop automatically (this can be done manually by selecting the STOPPING option in SYMBOLS). If the flame
turns off, the controller reports an error and stops the burner control. To resume the operation, manually select
the TURN ON option in SYMBOLS. Therefore, this is a type of semi-automatic operation.
PID
PID activation is smoother operation of the burner that gradually adjusts the burner output with an accuracy of
1%. During winter, this significantly increases the operating time of the burner after a single ignition.
Note: when the PID option is enabled, the regulator has more options in the menu - Advanced/burner/burning.
It is also required to set the parameters for three burner output levels, i.e. one level higher than when working
with the PID option off.
For the PID off, it is easier to set the burner because the parameters for the minimum and maximum burner
output are to be set. The regulator for the boiler temperature lower than the value of 1/2 hysteresis operates at
maximum output and after exceeding it (1/2 hysteresis) - at minimum output. When the boiler temperature is
exceeded by more than the set hysteresis x 2, the burner will be turned off.
Hysteresis
The parameter is of importance only for operation with the PID option turned on.
