High Gravity Brew's 330 controller for RIMS?

I’m looking to take my 5-gallon setup from gas to electric, and am looking at High Gravity Brew’s systems. I see that they have a 330 and a 350 controller. I’d rather run just a 30 A circuit to my brewing area, and not a 50 A if I could avoid it. The 330 says it cannot control two elements at the same time as could the 350.

My question is this: Is it possible to program the 330 controller to switch quickly between the HLT and RIMS elements - this way they would not have to run simultaneously, meaning I could use it for RIMS with a 30 A circuit.

I just switch the electrical cord from the kettle to the HERMS tank after mashing in.  The controller then heats the HERMS tank during step mashing with the temp probe on the return to the mash tun.  I use two mounted temp probes - one in the mash tun/ boil kettle and one mounted in the lid, switching them over for the step mash.
