No... the NVM is only a feature of the MC-B+ and Dial-B series controllers. Those controllers required a 9V alkaline battery to retain the correct time of day. The MC+ and MC-A+ required the Ni-Cad battery pack. The pack was a heat shrink wrapped set of 4 AA sizes Ni-Cad batteries. There was a way on SOME versions of the original MC standard controller to make them accept a Ni-Cad battery by installing a wire jumper between two points on the PCB.
