PART III: OPERATION

9.2 Oil thermostat adjustment
Progressive and fully modulanting oil burners are equipped with electronic multi-thermostat Danfoss MCX, whose operation is con-
trolled by thyristor. (for details refer to the attached technical documentation)
The oil viscosity at the nozzle, should be about 1,5 °E, which guarantees correct and safe functioning of the burner. The above tempe-
rature values are suggested and refer to a plant designed according to the prescriptions in the burner user manual.The suggested
values can change in reference to the fuel oil specifications.
