GRID
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:
Main menu
→
Boiler settings
→
Boiler

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 "grid"
and "pellets".
When using the grid an alarm "No fuel" can
appear. This alarm occurs when a
temperature drops below the value of the
parameter:

and then for a period of 10 minutes there
has been no growth.

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
