In PAUSE mode the boiler is being burnt off
and awaits the signal to start operation. The
following can be a signal to start operation:
Decrease of preset boiler temperature
below preset temperature diminished by
boiler hysteresis (
Boiler hysteresis
),
By boiler operation configuration with the
buffer decrease of top buffer temperature
below preset value (
Buffor loading start
temperature
).

GRATE
Some boilers have an additional grate to
burn other fuels such as wood waste, etc. To
activate the grid, move the parameters
available in the:

from "pellet" to "grid". In the grid mode fuel
feeder is turned off. The combustion process
is regulated by the fan. Fan power, when
working with grid, is set in:

allows you to define different properties of
boiler operation for operation modes "grate"
and "pellets".
When using the grid an alarm "No fuel" can
appear. This alarm occurs when a
temperature drops below the value of the

HOT WATER SETTINGS
The controller regulates temperature of the
silo of Hot Water HW, providing that the
temperature sensor is connected. When the
sensor is disconnected – the information
about it is displayed in the main window. By
