[TRNSYS-users] type32- log of negative number error

[Amirreza Heidary via TRNSYS-users]

Hi
In my simulation there is type 32 (Cooling coil). when I run my model
without an equation it runs properly. but runnig my model using the
equation (named Sum in model) it runs for first hours but it stops with the
following error. The equation is just some of the heat rates to be used in
plotter. following is the error and the simulation environment.
what should I do to solve it?
