[TRNSYS-users] type 32 (cooling coil) issue

Hi All,

I'm having some problems Type 32, the simple cooling coil. It crashes a 
little way into the simulation (at hour 607.75) with an error about an 
enthalpy <0. However, it's at a time when the coil has airflow but no 
water flow (cooling is not required at this timestep). I see in the code 
of type 32 that if either flows are 0 (actually, <1e-6) then it should 
simply set outputs = inputs and return. Any ideas what's going on?

Thanks,
Cramer
