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
