Fuel Type
III.e)
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.
Central Heating Pump Activation
III.f)
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
H.C.W. Pump Activation
III.g)
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

the boiler temperature drops below the activation temperature (minus hysteresis, e.g. 3
the pump will stop at boiler temperature of 37
Operation Mode
III.h)
With this function, you can select one out of four operation modes.
House Heating
III.h.1)
If you select this option, the regulator will switch to the house heating mode. The central heating pump
starts to run above the pump activation temperature (set to 35
