<P><FONT size=2>Ying,<BR><BR>If you have a heating coil in the air
handler one needs to inputm the HOT DECK MAX LEAVING TEMP (HEAT SET-T)- and
this enable the Heat Control input. The HOT DECK MAX LEAVING TEMP (HEAT SET-T)
should be set to the primary air temperature leaving the air handler. If the
HEAT SET-T air temperature is not specified, the primary air temperature will be
the mixed air temperature, which could result in a significant increase in
reheat energy depending on the climate. <BR>Hope this
helps,<BR>Mitch<BR><BR><BR>Mitchell J. Dec<BR>Senior Energy Analyst<BR>LEEDŽ
