• KIT (PC INTERFACE KIT):
cod.
3002719
• OUTPUT POWER REGULATOR KIT:
under modulating operation, the burner automatically adapts to one of an infinite number of firing rates
between the low and high flame output position, thus ensuring stable operating conditions in terms of temper-
ature or pressure.
Two components should be ordered:
– Power regulator to install to the burner.
– Probe to install to the boiler.
