Summary

The author describes the control functions which can now be provided by electronic devices. In particular, the sensing of temperature to actuate on/off or step controls can incorporate many limiting settings, warning levels, re-setting requirements and time delays as well as the switching sequences for electric or hot-gas defrost. Using programmed microprocessor systems reduces drift of set points and unauthorised tampering. It also increases accuracy. With electronics, many additional features can be incorporated without increase in price. Pressure transducers are not quite so well developed, but are available for condenser pressure control systems. D.W.H.
