An aircraft environmental control system (4) for controlling a temperature of a fluid, the control system (4) comprising: a first temperature sensor (30) configured to measure a first temperature and to generate a first signal, the first temperature being a temperature of the fluid, the first signal being indicative of the measured first temperature; an amplifier (76) configured to amplify the first signal; one or more processors (64) configured to, using the amplified first signal, generate a control signal for controlling the temperature of the fluid; and a second temperature sensor (68) configured to measure a second temperature, the second temperature being a temperature of an operational environment of the amplifier (76); wherein the one or more processors (64) are further configured to, responsive to the determining that the measured second temperature satisfies one or more predetermined criteria, modify a gain of the amplifier (76) and wherein: the aircraft environmental control system (4) further comprises a baseline signal generation module (70) configured to generate a baseline signal, the baseline signal being independent of the measured temperature of the operational environment of the amplifier (76); the amplifier (76) is further configured to amplify the baseline signal; and the one or more processors (64) are further configured to, responsive to the determining that measured second temperature satisfies the one or more criteria, modify the gain of the amplifier (76) using the amplified baseline signal.
