<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:

Cap/Control), restore the default in the reheat entry so it is blank. Make
sure the Hot Water Loop is still enabled as the zone heating source
though. Under the Preheat/Baseboard tab, specify Baseboard Source as the
Hot Water Loop. You can change the default entries for the baseboards
(pressure drop, delta T, valve, etc.) if applicable. Then for each perimeter
zone, go into the heating tab and change the Baseboard control to Thermostatic
if it isn’t already selected. I’ve had trouble getting the
Outdoor Reset selection to work and most of our projects have baseboards
controlled by thermostats anyway. You can also enter the capacity of the
baseboards for each zone or let the system self-size. This should work…if
not I’d be happy to look at the inp.<o:p></o:p></span></font></p>
