<p>1. A temperature controller (13) for a fuelburning heat source (6) comprising a pressure controller (9) for gaseous fuel and a d.c. voltage-measuring bridge (18), which includes an actual-value signal generator (17) and a desired-value signal-generating resistor (19) and delivers signals to a final control element (14) in the gas flow path (7) of the heat source (6), characterized in that the actuating signal is delivered as an electrical signal in parallel via a chopper (58) and a comparator (45, 46) to a delay line (54) and an operator (11, 8) and that the delay line (54) together with the output of the chopper (58) controls the final control element (14) via an output stage (56).</p> |
