Nest - Variable Speed Compatibility Question

I was told by my HVAC maintenance personnel that using the Nest thermostat wonít allow the variable speed fans to function properly causing inefficiency in the system. I have the same setup as shown in CB242ís first set of pictures for his downstairs configuration using the TCONT803AS32DAA thermostat. I donít want to purchase a Nest thermostat for this system and it causes issues. Can someone help with this?
