    Programming check. Heater and fan

    Here's my heater program using RT:
    Fallback OFF
    If Temp < RT+0.0 Then ON
    If Temp > RT+0.8 Then OFF
    If Temp < 60.0 Then OFF
    If Power Apex Off 002 Then OFF

    Would this be correct for my fan? And can I have the fan kick on if the power has been off for more than 30 minutes if the temp is over 77?

    Fallback OFF
    If Temp > RT+1.0 Then ON
    If Temp < RT+0.1 Then OFF
    If Power Apex Off 030 Then ON

    I know I'm missing the temp check portion of power is out.

    Thank you

    Do you have a battery backup?

    What you have listed here as the last line of the program is going to cause the fan to come on as soon as power is lost, and stay on for 30 minutes after power comes back. Do you want the fan to be simply ON if power is out for longer than 30 minutes and the temp is > 77?

    If so, a virtual outlet is necessary.

    Create a virtual outlet. I'll call it Fan-PowerOut

    [Fan-PowerOut]
    Set OFF
    If Temp > 77.0 Then ON
    If Power Apex OFF 030 Then OFF


    [Fan]
    Fallback OFF
    If Temp > RT+1.0 Then ON
    If Temp < RT+0.1 Then OFF
    If Outlet Fan-PowerOut = ON Then ON
    Please do not send me PMs with technical questions or requesting assistance - use the forums for Apex help. PM me ONLY if the matter is of a private or personal nature. Thanks.

    Yes perfect thanks.
    Do my temp variances settings make sense to you?

    now that I think about this I don't think this is necessary because for some reason I had in my head that if power was out then my fan would be out but that should not be the case. If power is out the apex will still monitor temp and will turn the outlet on if it needs it. Correct?
