I have a problem in understanding the explanation of the input “deltaTempForNatVent_” .
A number or list of numbers between -100 and 100 that represents the temperature differential between indoor and outdoor below which ventilation is shutoff. This should usually be a negative number so that you open the windows when the outdoors is cooler than the indoors. This can be either a single number to be applied to all connected zones or a list of numbers for each different zone.
The differential between indoor and outdoor means: Tin - Tout
So if Tin is 20 C and Tout 18 C , the deltaT should be 2 C and not -2 C as suggested in the explanation.
The second problem gives me the phrase “below which ventilation is shut off”
If deltaT is a negativ number this would be strange.
