<DIV><FONT face=Arial size=2>Hello,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I need some help with modelling Radiant floor heat
in slab on grade from a natural gas boiler with an air-cooled chiller/AHU
both for the same thermal zone. When I put the thermal zone on the
AHU, the cooling coil shows up on the chilled water loop but not the boiler
loop. When I put the thermal zone on the radiant slab, it shows on the hot
water loop but not the chilled water loop. I can't get the radiant floor
to show on the heating side of the AHU as an alternate heat source, but I'm not
allowed to have the same thermal zone on two different systems. Can anyone
please help me?</FONT></DIV>
