So, simply, i turn to detailed HVAC mode, and I select unitary Air to air heat pump, cause this is the type of heat pump i want to use, i select the zones, No need to use a simple hvac template, but i edit it to match the settings COPs for heating and cooling are 3,5 and 3. Finally, the consumption of the heat pump for heating is so high, like (3 to 5) times higher than the needs, it suppose to be lower, i tried to modify some settings, but I'm not too familiar with all the sittings, So what could be wrong with my settings, I'm trying for more than a week now, Results make no sense at all, Help please,

@Ali__ are you editing COP in the edit window of the heat pump (part of the Detailed HVAC diagram screen), or editing COP in the HVAC tab (where you select HVAC system template)? If you are using detailed HVAC mode, you should edit COP in the detailed HVAC diagram.

@aaron-boranian i think that this could be the source of the problem, i used Unitary Air to air Heat pump, i didn't touch any of the performance curves since it was predefined, i'm not an expert in Heat pumps, there were 5 performance curves, so i don't know exactly what to change and how i can get those curves to match my system. Please check the link for screens. https://drive.google.com/drive/folder...
