10.0pt;font-family:Arial;color:navy'>In this context, “explicitly”
means entering a non-zero value for fan SUPPLY-STATIC or SUPPLY-KW/FLOW when
using eQUEST. Most likely you will be modeling the fan as continuous anyway
(per G3.1.2.4) but even if you model it as cycling you will need a non-zero fan
power if you let eQUEST calculate the EIR. <span class=GramE>eQUEST</span>
converts SEER and EER to EIR which has no fan power, then adds fan power in the
form of SUPPLY-STATIC. (Someone please correct me if I’m wrong.)<o:p></o:p></span></font></p>

definitive. I’m still trying to figure it out.<o:p></o:p></span></font></p>
