Abstract

Circuit to control a gas-heated circulating water heater with a relay, the coil of which is connected to an operating voltage via at least one resistance, there being arranged parallel to the coil (15) of the relay both a capacitor (21) and a switch (23) of an air deficiency safety device, a second switch (11/12,30) lying in series with the relay coil (15) in such a manner that the relay has a self- holding circuit (12/13) and that the latter during self-holding separates the relay coil from the capacitor and from the switch (23) by means of the second switch, a third switch (17) being arranged in series with the relay coil (15) and it being possible to pick up a signal for the freeing of the fuel path (3) directly at the connections (7, 8) of the second switch (11/12 or 30). <IMAGE>
