VICTRIX 50 Rev. 002 

  VICTRIX 50 operating sequence.

Heating phase.

Power on

Main switch ON

Powering the circulator

The integrated board powers the boiler circulator

Burner ignition (automatic slow ignition)

The integrated board keeps the fan working at ignition speed

Flame detection

By means of the ionisation electrode the control unit detects burner ignition and sends the signal to this effect to 

the modulating control board

 

Room thermostat switch closing

A room thermostat request shows conditions that require the central heating function

Boiler working

The burner works at a power that varies according to the type of request, to the adjustments/settings made and to the temperatures 

detected by the NTC sensors.

Integrated board operation enabled

Closing of the main switch contacts (ON position) enables operation in the central heating mode

System pressure micro switch closing

Pressure in the primary circuit higher than the minimum shut-off value causes the pressure switch micro contact to close

Powering the fan

The integrated board powers the fan and manages its speed

Powering the ignition electrodes

When the fan reaches the speed in the ignition phase, the integrated board powers the ignition electrodes

Powering the gas valve coils

The integrated board powers the gas valve coils

Safety thermostat switch closing and flue thermostat

Closing of the safety thermostat contacts and flue thermostat enables the boiler to work
