Dear Salim,

To control your room temperature with a PID, you should have a look to the example " PID- Cooling Power". This example shows you how to maintain 20°C in your room (for cooling, not heating but it's the same). You will then be able to adapt that example to your model with type56.

The output of your PID give what you need to maintain 20°C (your setpoint) in your room (heating when >0, cooling when <0). Then connect your PID output as internal gain from your thermal zone in type56 (only >0 values for heating)

Best regards

Dear all,

 

As a new user, I need to know how to control the zone temperature of a multizone bulding (type56) using a type23 PID controller. I defined an input heating power in trnbuild which would be the output of type 23 (control signal). The heating setpoint is fixed to 20 °C. The result was not satisfactory, as the temperature remains lower than the setpoit and does not oscillate.

 

Thank you
