Dear eQUEST experts,

The design model that I?m working at has many thermal zones with adequate
cooling and heating capacities (Per final Mechanical documents). Total
hours above COOLING THROTTLING RANGE for the project is 82 and total hours
below HEATING THROTTLING RANGE is 202. The HVAC systems have economizer and
heat recovery.

The simulation report shows the following warnings for almost all the
zones.

I would appreciate it if you would tell me what caused these warnings an
how I can solve the issues.

**WARNING**********************************************************************
SYSTEM ECCNSys1 (PSZ) (G.NW2) may have inadequate
cooling capability
Check COOLING-CAPACITY and MIN-SUPPLY-T for consistency

**WARNING**********************************************************************
ZONE ADMISouth Perim Zn (G.S6)
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.)
