II.e) Fuel Type
This option allows you to select one of three fuel types (coal, fines and
wood) for use in the boiler. Each fuel type has a fan operation mode assigned
to ensure the right burning process.
II.f) Central Heating Pump Activation
With this function, you can set the temperature that will activate the
central heating pump (the temperature is measured on the boiler). The
pump will start if the setpoint temperature is exceeded. The pump will be
deactivated when the boiler temperature drops below the activation
temperature (minus hysteresis, e.g. 2
O
C). In this case, the pump will stop at
boiler temperature of 33
O
C.
II.g) H.C.W. Pump Activation
With this function, you can set the temperature that will activate the hot
consumption water pump (the temperature is measured on the boiler).
Above the setpoint temperature (e.g. 40
O
C), the pump is activated and
operates depending on the selected operation mode. The pump will be
deactivated when the boiler temperature drops below the activation
temperature (minus hysteresis, e.g. 3
O
C). In this case, the pump will stop at
boiler temperature of 37
O
C.
