1. A universally applicable control device for a gas-operated heating device having more than one burner, the control device comprising: a first valve (1) and a second valve (2) connected (28) to each another in a gas-tight manner, wherein the first valve (1) has an ignition lock which closes the main gas flow during ignition, a thermoelectric ignition fuse (11;12;13), and a thermostat (19), wherein the gas flow is switched on and off via start-up (14), wherein the first valve (1) has a first gas outlet (6) for the connection of the second valve (2), which is arranged downstream of the ignition fuse (11; 12;13) and upstream of the thermostat (19), and has a second gas outlet (7) which is downstream of the thermostat (19) and which leads to first burner (26), and wherein the first outlet (6) of the first valve (1) is connected to an inlet (8) of the second valve (2), and an outlet (9) of the second valve (2) is connected to second burner (27) and wherein the second valve (2) comprises a thermostat (20) wherein both valves (1;2) have approximately the same pressure drop across between inlet (5) of the first valve (1) and the outlets (7;9) of both valves (1;2), enabling the two burners (26;27) to be operated.
