<br>Dear Mr. Adrien,<br><br>Many thanks for your patient and careful answers!<br><br>You are right!<br><font color="#3366ff">Set point for cooling is 26°C in your model.
      The problem comes from your ventilation system : Temperature of

        You are right. The problem is indeed Internal Gains. I define a

        than the previous. However, there are some unreasonable

        1. Tair and Top are higher than the set point 21 °C in winter
        all the time. Tair is closed to 23 °C basically, and it is only
        21 °C when no occupancy. I guess the reason is the compensation

        I would like to ensure that the set point is 26 °C in summer. Do

              You are right : the Tcool I gave you was equal to 26, not
              to 24°C. Tset value is not important as well, the most
              important is that you understand how to do to define Tset.<br>
              In your model, your heating and cooling advices seem to
              work fine. Your problem comes frome your internal gain :
              31 people are defined all the time in a room of
              approximatively 80 m², without schedule. <br>
              Because of your important internal gains, air temperature
              increases until 35°C in winter. Then air temperature is
              refreshed because Tcool = 35°C in winter.<br>
            </div>
            In summer, air is cooled at 24°C, because this is the

                                becomes 35 °C also not 21 °C, although I
                                set heating temperature as 21 °C; in
                                summer, however, indoor temperature
                                becomes 21 °C. Please see the Attached
                                On-Line Plotter image.<br>
                                Furthermore, when I create another Tcool
                                equation as <span style="color:rgb(51,51,255)">35*winter+24*summer</span>,
                                the result is also like the Attached

                                <br>
                                Please give me some solutions or
                                advices! <br>
                                I think the point how to set that
                                Cooling doesn't work in winter? The
                                possible reason of that problem is that
                                I also set a Mechanical Ventilation in
                                winter (Tset=19 °C) and summer </font><font size="4">(Tset=17 °C). I guess Maybe </font><font size="4">the Mechanical Ventilation will

                                          Dear all,<br>
                                          <br>
                                          I cant make type673 heating
                                          mode to work. Cooling mode
                                          works just fine but when I
                                          change the cooling control
                                          signal to 0 and heating
                                          control signal to 1 it doesnt
                                          work anymore. When the heating
                                          mode is used nothing happens.
                                          Does anyone know why?<br>
                                          <br>
                                          Best regards,<br>
