This micro-processor based controller directly replaces the earlier PSM72. It allows manual start - stop in bad weather conditions that a conventional keyswitch could not provide. Timed Pre-Heat with LED indication together with engine protection for Low Oil Pressure, Cooling Fault and Over-crank. Customised versions and customer specific software is available to order. Note: the PSM720 shares the same connections with the ASM720 series and thus provides an upgrade path from manual start - stop to full auto-start control.
