Hi everybody !
I am writing you today to ask you some questions that I did not find somewhere else. Maybe this is obvious but there is something I do not understand.
I am trying to find the HVAC economy that I am doing with shading device. My problem is that I do not really understand the operation of the setEPZoneThresholds component.
1) What represent cooling set point/cooling set back and heating set point/heating setback ?
Lets see why I do not understand.
Here I put 17C for the heating set point and 27C for the cooling set point. However, after calculation inside temperature is still 28C (more than 27C, this is one of the reasons why I do not understand the setEPZoneThresholds component).
Then, to compare, I tried to take the cooling set point over 27C, namely 35C. Then my inside temperature is higher than the previous one, which is understandable because my set point is higher too.
Now an other problem, the mechanic ventilation energy increase, while the inside temperature is high and does not needs as HVAC as the previous example . It does not make sense.
Can you please explain me how this component works?
2) Is this way is the best way to know the economy of HVAC ?
I saw this other way about HVAC cost but numbers are totally different so I guess that it does not represent the same thing.
What is the difference between the mechanic ventilation energy and these values ?
Thank you in advance for your help.
