[TRNSYS-users] Controler Advice for evaluating Solar Radiation?

[Jeff Thornton via TRNSYS-users]

Javier,

Since the value you are watching won't change with the control decision, you don't need a controller with hysteresis.  I would simply use an equation:

Glim = 1000
On_Controller = GE(IncidentRadiation,Glim)

where the incident radiation is an input to the equation component.

It is simple, if the total radiation on the surface is below a Glim, I need the controller to output 1. If the total solar radiation is above Glim, set 0. The controller output will be used to divide a certain flow.
