Principle of action of HYDRONIC B5W S.
At inclusion the control bulb on the control panel lights up (pass the relay, the modular relay). The water pump and according to the set program with preliminary washing and calcinating by turning on of the supercharger of air in the combustion chamber turns on, a bayonet electrode of incandescence and the fuel dosing pump burning process begins.
At formation of stable process of burning through certain time bayonet the electrode of incandescence is disconnected.
Depending on the necessary temperature of heating change of productivity of HYDRONIC on steps is carried out:
"High" and "small". At the same time temperature thresholds are rigidly programmed in an electronic control unit.
If the need for heating at a step "SMALL" it is so small that temperature of cooling liquid
reaches 85 °C, the heating device passes to a step of "VYKL". It is in conclusion made inertial выбег during apprx. 130 seconds. The control bulb burns, the water pump also continues to work during a regulation pause.
