<p class=MsoNormal><font size=2 color=navy face=Arial><span lang=EN-GB
style='font-size:10.0pt;font-family:Arial;color:navy'>I have a SZRH system
which should provide outside air to the FC system. The air it provides should
always be 68 F. What temperatures shall I put for cooling design and heating
design / thermostat setpoint T. I put min supply temp and max supply temp to 68
F and the other design temperatures to 53/90F cause I do not have a thermostat
there ( the air is always provided with 68 F). Then I specified the OA constant
to 4000 cfm and determined the min outside air ratio =1. Is there sth wrong
with my temperature settings as I do not get any coil loads for the system
(SS-J report)? When I set all temperatures to 68 F the ventilation air I
require is too huge. Do I have to put the min OA ratio to 1, 0 or shall I leave
it blank for the FC system? I mean is it enough to put OA from system SZRH?
Cause someone told me I have to put it to 0 as I do not have any outside air
put I do it is from the system. I am confused. <o:p></o:p></span></font></p>
