ximum rotational speed while starting. The parameter set in this way will
allow to avoid any problems with the device for a long period of its use.
- INDOOR ADJUSTER the device offers the possibility to connect an
indoor thermostat responsible for maintaining the temperature within the
rooms heated. The room thermostat controls the operation of the
central heating. It switches on or switches off the pump depending on
the temperature. When the thermostat is connected to the adjuster, yes
should be pressed in the function. An arrow will appear in the upper right
corner on the display.
CAUTION!!! the function should not be enabled when no indoor thermo-
stat connected.
- WORM TEMPERATURE the function together with the sensor placed
on the pipe of the feeder allows to protect the boiler from an embers/fire
return to the fuel storage container. When the temperature measured on
the sensor exceeds the set value, the error E7 'Temperature of the worm
sensor too high' will appear on the display. The airflow will be switched
off, the feeder will start transporting the fuel
FUEL COMBUSTION SETTINGS MODIFICATION
Two checkup tests should be introduced to each of the types of fuel that
is supposed to be burnt, a minimum power test and maximum power test
for the boiler. The test is based on adjusting an adequate amount of the
fuel for two limit value of the boiler power. The boiler power is an air
amount distributed to the hearth through the fan. For the parameters:
Min fan power, e.g. (15%) and max fan power e.g.: (99%), an adequa-
te amount of fuel is adjusted. An adequate adjustment and proper te-
sting ensure a steady power adjustment and the adequate amount of
transported fuel within the full range of the boiler operation (15% - 99%)
- MINIMUM FAN POWER the parameter is intended for determining a
minimum fan rotational power (minimum boiler power). This value is de-
termined once for a particular fan type. The value should be set so that
the rotor's blades operate with the lowest rotational speed as possible.
You cannot overdo it, the rotor must be working! Stopping the rotor will
cause a break in oxygen transportation, which will result in incorrect fuel
combustion on the hearth an disable proper testing for the minimum
power. In order to determine correctly the minimum fan power, using the
keys ( )( ) the parameter should be set and then the key ENTER
should be pressed. The device will perform the test. The parameter
should be determined on the basis of an observation of the rotational
speed of the fan's rotor.
