[esp-r] Re: control issues

[Jon Hand]

First suggestion - create a model contents report.  ( browse-edit-simulate ->
results & QA reporting )  Look at the section of the report that
deals with control.  Check that you have associated the control loop with zone1.

Next consider what kind of control are you using.  The 16 degrees is probably the
heating setpoint but is the 18C a cooling set point or a throttling range for a PI
controller?  PI controllers often need to be tuned.  Try a basic control with a
heating set point of 16C or 17C instead.

Subject: [esp-r]  weird phenomen

Hi all,

I have a control in my model that gives 20kW of heat power to zone1. The temperature is asked to be between 16 and 18. However, he seems not to get it. He keeps below, even without achieving the maximum heating power.

Can anyone suggest me how to solve that?

it is Jon's ESP-r for windows ..
