[TRNSYS-users] By-pass in TRNSYS

[Adrien JEZEQUEL - ITF]

Dear Cristi,

You may build a schedule with equation tool or use special type in 
TRNSYS to define your seasons.
With equation tool you will have something like :

  * WINTER = LT(TIME,1920)+GT(TIME,8520)
  * SUMMER = GT(TIME,4848)*LT(TIME,7056)

Then, control your exchange with an equation like

  * EXCHANGE = WINTER + SUMMER

Your exchange works in winter and summer (=1), and by pass (=0) the rest 
of the time

Best regards
