+For rsType=ASHP, rated heating capacity at outdoor dry-bulb temperature = 47 ^o^F.
+
+If both rsCap47 and rsCapC are autosized, they are set to consistent values based on the relative values of heating and cooling loads.  If the autosized capC is greater than 75% of the autosized cap47, then rsCapC is set to autosized capC and rsCap47 is derived from rsCapC.  Otherwise, rsCap47 is set to 75% of autosized cap47 and rsCapC is derived from rsCap47.
