The burner is delivered with a temperature gauge PID regulator, it regulates the wanted running temperature of the
burner and a lambda sensor, which controll exhaust gas parameters.
The regulator with cooperation with lambda sond measures and controls adjustments for achieving and holding on
required temperature by activating full modulational oparation of burner, this reduces the number of start ups and
saves fuel. The regulator’s gauge displays the current boiler temperature in the display-panel of the boiler’s MPU
Controll Unit.
Ensure the immersion temperature gauge cannot release from the boiler.
The burner’s MPU control unit should be connected to 230 volt mains electricity from the main supply box.
Connect boiler’s overheating security system to right clamps into MPU unit. If the boiler overheats the overheating
security system acts as an emergency stop for the burner. The overheating security system should only be installed
to be re-set manually.
