<br>
<br>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).
<br>
<br>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.
<br>
<br>Does anyone know how to control the pump according to plant component
output (temperature) ???
<br>Did I use the right components for that?
<br><br>Thanks!<br>Best regards<br>Bernd<br><br><br>Ctl File:<br><br>no overall control description supplied<br>* Plant<br>no plant control description supplied<br> 3 # No. of loops<br>* Control loops<br># senses var in compt. 5: Source @ node no. 1<br> -1 5 1 0 0 # sensor <br># plant component 4:Pump_u @ node no. 1<br> -1 4 1 0 # actuator <br> 1 # No. day types<br> 1 365 # valid Fri-01-Jan - Fri-31-Dec<br> 1 # No. of periods in day<br> 9 8 0.000 # ctl type, law (On-Off control.), start @<br> 7. # No. of data items<br> -1.00000 19.00000 20.00000 0.00500 0.00000 0.00000 0.00000<br>* Control
