How to input HIU into netsyshttps://communities.bentley.com/products/building/performance/f/hevacomp-forum/170202/how-to-input-hiu-into-netsysI have a project which is utilising heat interface units for heating and domestic hot water. how can HIU be input to netsys system. Heating side of unit uses different temperature difference from domestic hot water side.

Depending on the use - for example the HIU at the start of the schematic - the system marker should be considered the HIU. If you had multiple HIU&#39;s spread through the schematic, then you would have to split your schematic and use a system marker in place of the HIU.<br /><br /><br />Regards,<br /><br /><br /><br /><br /><br /></p><div style="clear:both;"></div>
