The cooling performance data should be entered at a dry bulb of 26.67 C 
and a wet bulb of 19.44.  These can be found in the cooling correction 
data file - at the point that corresponds to a multiplier of exactly 1.0 
for the multiplier values:

1.00	1.00	1.00	!Multipliers for Total Capacity, Sensible Capacity and 
Power at 26.67/19.44

In a similar way, you can see that the heating performance should be 
entered at an air temperature of 21.11 C

1.00 	       1.00               ! Multipliers for Heating Capacity and 
Power at 21.11
