Keys to Modeling a heat pump in TRACE 700: 1) Create a backup heating plant (this should actually be your first step). You should technically have 1 backup heat plant for each cooling plant (even if in reality - this never operates). Do not set the capacity to zero - regardless of what you have heard in the past.
