    Heater Outlet Turning off too early

    I have my Temp set to be between 77 and 78 degrees. My outlet turns on when it reaches below 77 degrees F. but it turns back off, rather than heating until 78 and shutting off. so basically its on at 76.9 off at 77. constantly. What in my programming is wrong?



    Fallback OFF
    Set OFF
    If Output New_Fish = ON Then ON
    If Temp > 78.0 Then OFF
    If Temp < 77.0 Then ON
    If Output Pumps_2_3 = OFF Then OFF
    If FeedA 000 Then OFF

    You have to remove the set OFF if you want hysteresis.

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