Dear Guy THOMAS,<br><br>The capacity is usually the dependent variable in the performance map of many - if not all - of these heat pump components. If you would like to have capacity as an independent variable, I would recommend using the Type42 performance map component (HVAC > Conditioning Equipment) with your own data set.<br><br>Best regards,<br><br>Matt Duffy<br>

Hi,<br>I'm using Type 668 single stage heat pump and  I would like to be able to have a control of capacity until 50% of the heating capacity. Is there any type which can help me to do that? Or is it possible to read various data file for each level of heating capacity?<br>Best regards<br>Guy THOMAS<br>                                     </div>
