[Equest-users] stumped re. excessive heating

I have a proposed building in a  tropical climate with CHW cooling and 

no heating. Per ASHRAE I'm installing electric heat in both the Baseline 

and Proposed models. The heating in the Proposed is double what it is 

in the Baseline. Worse yet, I am getting the following warning:



             ZONE EL1 East Perim Zn (G.E19)       

             might have insufficient heating capability.

             Check that the SYSTEM or ZONE HEATING-CAPACITY plus this

             ZONEs BASEBOARD-RATING is adequate to maintain the ZONE

             specified DESIGN-HEAT-T for the calculated peak ZONE load

             (see LS-A or LS-B for the ZONE peak load.)


             SYSTEM UMA 102                         

             which supplies the above listed ZONE, has a design heating

             coil exit temperature, HEAT-SET-T,(plus any zone reheat)

             below its MAX-SUPPLY-T or the ZONE DESIGN-HEAT-T, which

             might account for the insufficient heating capability.



Does eQUEST overcompensate for an erroneous config for heating such that 

it would behave this way? What should I look for?


Thanks in advance.
