Has anyone in the group used the sunspace option in eQUEST? I have tried it and it blew up in LOADS Following is the .inp description of the Sunspace:

"EL1 North Perim Spc (G.N1)" = SPACE

Following is the system description of the sunspace:

"EL1 North Perim Zn (G.N1)" = ZONE

BASEBOARD-RATING = -25605.4

FLOW/AREA = 0.25

SS-VENT-SCH = "Sunspace Venting Schedule"

DESIGN-HEAT-T = 72

HEAT-TEMP-SCH = "S1 Sys1 (UVT) Heat Sch"

DESIGN-COOL-T = 75

BASEBOARD-CTRL = THERMOSTATIC

SIZING-OPTION = ADJUST-LOADS

SPACE = "EL1 North Perim Spc (G.N1)"

..

"EL1 North Perim Pl Zn (G.N6)" = ZONE

TYPE = UNCONDITIONED

DESIGN-HEAT-T = 67

DESIGN-COOL-T = 75

SIZING-OPTION = ADJUST-LOADS

SPACE = "EL1 North Perim Plnm (G.N6)"

Following is the error message

***ERROR***********************************************************************

In routine TEMDEV for ZONE EL1 North Perim Pl Zn (G.N6) on 2/10 hr 11 (InitialFlg = 0)

SUNSPACE INTERIOR-WALL calculations produced bad values:

CSSVEC (convection) = 0. CSSVEC (conduction) = 7294864.

This would cause a 262. degree ZONE temperature change. Values are being ignored.

Check wall definitions for errors and report this inp/lib/wth to DOE-2 support.

Any ideas as to where I went wrong?
