Hello,
I would like to modelize a manual night ventilation. For that I need to keep the value of temperature for the time X (for example 17 pm) and compare this value with a set temperature during a given period (for example a night).
I don't know to keep a value in a variable during a given period. Could anyone help me?
I began with the following formulas but when the condition of the first variable is not checked it returns 0 and the third variable doesn't return what I want :
T17h = eql(mod(TIME,24),17)*temperature_zone10
periode = or(lt(mod(TIME,24),9),gt(mod(TIME,24),17))
vnat = gt(T17h,24)*periode*2
Thanks a lot for your help.
Best Regards,
Pauline GELIN
