[TRNSYS-users] Equation

Dear all,

    I want to design an EQUATION to control the Opening Factor of the window
(Input of TRNFlow) as 1:

every 2 hours (starting at 10 am)  the windows are fully opened (OF=1) for 5
minutes.
every 1 hour (starting at 9 am) the windows are fully opened (OF=1) for 5
minutes.

Many thanks in advance!

Br.
