摘要

Central heating burner control has a change-over switch (12) which allows it to be connected either to the mains (5) or to the auxiliary d.c. supply via the inverter (17). The switch is operated manually or automatically while the auxiliary supply is ensured by a car battery which is recharged by running the engines at a high idling speed. The inverter with transformer and terminal as well as with indicator can form a separate set.
