Fred,
 not in the case of Type668 because that value is a parameter and not an 
input (ie it is set once for the simulation). We do have some other heat 
pump models that are multistage (and a multistage controller that goes 
with it). With the components that are in the standard TESS HVAC 
library, you'd have to use multiple Type668s in order to model that.
best,
 David
