[TRNSYS-users] TRNSYS time equation

[adnan rasheed]

Dear Marion Hiller ,
 i checked Type 14 output will not work in this situation.
Actually i want to control natural ventilation window open and close
according to the set point, at the corresponding time span. As i write
before  temperature is room temperature, on behalf of that window should be
open and close. if room temperature is high than the set value at
particular time span window should open (natural ventilation).

00 to 5h.... temp set point 18 C
5-10h....  temperature set point 22  C
10-18h....23  C
18 -24h...24  C

Thanks
