<p class=MsoNormal>Hi Arnaud<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>1. Yes, you have to connect your heat pump to the ventilation
of type 56 (airchange + temperature + RH)<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>2. It is a good way to control your heat pump with Type2,
however, I'm not quite sure if the way you entered the inputs is good. I'd
recommend you connect the room temperature to your upper input temperature,
enter 14 C in the lower input temperature, then enter the dead band you wish in
upper dead band temp (e.g. 8 if you want the HP to stop working when the room
temp is 22C) and put the lower dead band temp to 0. (also, make sure you also
connect the output of type 2 to the "input control function" to make
sure the hysteresis works well). Then, you have to take the opposite of the
output signal to make it work properly, so just open a new equation and use the
function NOT: Heating_signal=NOT(old_heating_signal). Finally, connect this new
signal to the control signal of your HP.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>3. When you get a lot of oscillations like that, it means
that your HP is a bit oversized or that your deadband is too small, try to play
with both if you want to get rid of some oscillations.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I hope this helps.<o:p></o:p></p>

<p class=MsoPlainText>Good morning everyone,<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>I connected Type 665 ( air/air heat pump) to the
ventilation of type56.<o:p></o:p></p>
<p class=MsoPlainText>However, I don't manage to control properly the Heat
pump.<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>At the moment, the heat pump is control by a type 2
component. But it seems that there is a problem of information transmission
between the heat pump and the controller.<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Enclosed, a file where it can be seen the controller
setting and the heat pump working.<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Is it the best solution to connect the heat pump to the
ventilation? Should I use the gains instead?<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Best regards,<o:p></o:p></p>
