<font size="-1"><font face="Arial">Dear Salim,<br>
<br>
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.<br>
<br>
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)<br>
<br>
Best regards<br>

<p class="MsoNormal"><span lang="EN-US">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.<o:p></o:p></span></p>
