[esp-r] plant control: sense plant output

[Bernd B.]

Dear all,



I would like to control the flow of a pump (type 15, variable speed 
domestic WCH pump) according to the temperature of a specific plant 
component. In my case the component is called "air & water temperature 
source" (type 24).



I already tried the controller types 9 (senses plant output; actuates 
flow), 16 (senses plant output; actuates variable), 22 (senses plant 
output; mass ration). All were connected with an on/off-controller. I 
got results without an error during the simulation. However the pump 
didn't run or react. I have already checked the setpoint and so on.



Does anyone know how to control the pump according to plant component 
output (temperature) ???

Did I use the right components for that?


Thanks!
Best regards
Bernd
