I'm sure you're speaking about the 0°C-timeswitch. Is it located on the body of the thermostat near the thermo-timeswitch?
In this case this 0°C-timeswitch is used in all 323i from 09/1980 and younger. It is responsible for the complete cut-out of the valve that injects fuel in case of cold-starts after the initial injection at temperatures of more than 0°C (= 32° Fahrenheit).
In older 323i there is a weaker and secondary fuel injection of this valve after emiting the mean part of additional fuel at cold-starts. But this secondary fuel injection is only needed at temperatures below 0° C. So this timeswitch was introduced in 09/1980 for cutting off the secondary injection and so it was saving fuel at temperatures over 0° C.
