    I cannot get my heater to stay on when in Auto

    Hello everyone! I am new to the world of Apex and have been messing around with my new Apex EL for the last couple days. I set up my ATO, Return Pump, etc. However, I want to set up my heater so that it turns off if less than watts and greater than amps. I set my Amps lower than normal on purpose to test and it does turn my heater output off but I cannot get it to turn back on in Auto. When I turn it to on then it will stay on but when I turn to Auto it will revert back to Off.

    I also want my heater to turn off if I shut down my retun pump for water changes, feedings, etc.

    See programming below. Is this correct?

    Fallback OFF
    If Tmp < 77.8 Then ON
    If Tmp > 78.0 Then OFF
    If Output RETURN_PUMP = OFF Then OFF
    Set OFF
    If Output SUMP_HEATER Watts < 250 Then ON
    If Output SUMP_HEATER Amps > 2.8 Then ON

    Remove the Set OFF.

    I don't understand the rationale behind the watts and amps conditions. What are you trying to accomplish here?

    I STRONGLY suggest you remove those last 2 lines until you are sure what you want it to do exactly.

    I want to turn off my heater if it goes below a certain threshold of watts and above a threshold of Amps. To prevent an issue with a malfunctioning heater.

    You are telling it to turn on when the heater is drawing less than 250 watts and on when drawing more than 2.8 amps. That does not turn it OFF. Both statements turn it ON when those conditions are met.

    Watts = Amps X Volts

    Ok so how do I make it work? I also tried it with off and it still doesnt work. I also tried it without the set off and still nothing.

    If Tmp < 77.8 Then ON
    If Tmp > 78.0 Then OFF
    If Output RETURN_PUMP = OFF Then OFF

    This will turn the heater on when the temp is 77.7 and off when it hits 78.1.

    What exactly are you seeing? If the temp is between 77.7 and 78.1, the heater will not turn on until it drops to 77.7
