BOILER START-UP

Use the „+” and „-” buttons to respectively increase or decrease the preset emission
temperature; please note that the value in the upper part of the thermometer symbol is x10,
e.g.: 20°C, means 200°C. The preset emission temperature should generally be between 160
and 250°C.
The optimal preset emission temperature depends on the type of fuel and the heat necessity,
and it should be determined experimentally. When burning wood, the flame should be blue-
yellow, and when burning coal – yellowish. For example, the optimal temperature for wood is
between 190 and 260°C.
If optimal emission temperature causes excessive heating up of the boiler, it is best to store the
surplus energy in a thermal buffer. If the central heating system does not feature a thermal
buffer, you must find such preset emission temperature at which the temperature of water in
the boiler is at the desired level. If it is too hot in a room, decrease the preset emission
temperature, and increase it in the opposite case. The preset boiler temperature is in this method
of secondary importance, it prevents exceeding undesirable temperature of the boiler. It is
recommended to preset the boiler temperature as 10°C higher than the expected boiler
temperature after the emission temperature settles. After the boiler reaches the preset
temperature, the regulator switches to SUPERVISION mode.
Note: the regulator will automatically switch from regulation mode 3 to mode 1, if the
emission sensor is damaged or if the emission temperature exceeds the emission
sensor measuring capacity. Therefore, it is important to set proper parameters for the
regulator to operate in mode 1, without causing any danger.
Setting emission temperatures lower than 160°C can cause condensing in the
chimney!
If PID-S mode is chosen, it is recommended to use combined with a buffer tank.
High emission temperature, even if the fan rotates slowly, can mean that the
boiler is blocked of ash and need to be cleaned.
If emission temperature reaches higher than 400
o
C the boiler will stope and
alarm will be activated.
