Jandy VS PlusHP

I am looking to replace my Jandy PHPM1.5 pump ( rebuilt and is acting up again ) with a variable speed pump to save on electricity costs. Jandy VS PlusHP seems to have same dimensions so I don't have to worry about plumbing. Any comments/experience on this pump? To qualify for $350 rebate apparently i need the dealer to program. Is there ways I can override programming? Also I have a Jandy lite 2 heater how does this pump know the when the heater is on to operate at higher speeds? Thanks in advance for feedback.
