    air vent

    Hi, I'd like to program my air ventilation in the following way.

    If temp < 25 then it works 10 minutes every hour.
    If temp > 25 then it works 45 minutes every hour


    I have no idea how to do it.

    You have to use virtual outlets.

    FanHigh
    OSC 000:00/045:00/015:00 Then ON
    If Temp < 25 Then OFF

    FanLow
    OSC 000:00/015:00/045:00 Then ON
    If Temp > 24.9 Then OFF

    Fan (physical outlet)
    Fallback OFF
    Set OFF
    If Outlet FanHigh = ON Then ON
    If Outlet FanLow = ON Then ON

    You might be an engineer if...You have no life and can prove it mathematically.
