Dear Energy Modelers,

I am doing an office building simulation. The proposed building is VAV
system with electric heating source. While the baseline is system 6
Packaged VAV with PFP Boxes.

The simulation run for the proposed building came across results with very
strange unmet load hours "*HOURS ANY ZONE ABOVE COOLING THROTTLING RANGE =
8760*". On other hand the baseline is ok.

I would like to know if there is a way to verify such strange result.
Furthermore, the proposed building has Zone Thermostat Throttle Range 5?R,
and Indoor Design Temp. 72 F/70 F Cooling/Heating.

I would greatly appreciate your thoughts on this matter.

Regards,
