VA Pilot Duty ratings permit the connection of relays, solenoid valves, lamps, etc. whose total oper-
ating load does not exceed the published rating and whose total inrush does not exceed 10 times the
rating.
Running and locked rotor ratings are intended for motors. VA and VA Pilot Duty loads may be added
to a motor load provided the total load does not exceed the published rating.
OPERATIONAL TIMINGS
The BurnerPRO is pre-programmed from the factory with a set of operational timings necessary for
the safe operation of the burner system. However, operational timings can be modified via the mod-
bus port. The operational timings are governed by regional and local codes. It is important that the
appropriate operational timing is selected for the burner application.

See Table 7 on page 23 for expanded timing information.
