    Heater Temp

    Hi,

    The temp in the tank won't go above 77.8 even though the temp is set to go off at 78, my target temp. The heater is shutting off before it's supposed to.
    Here is what I have programmed.

    fallback off
    set off
    if 125tem < 77.8 then on
    if 125tem > 78.0 then off
    if feedA 000 then off

    This is happening on multiple tanks. What is the offset?
    The offset is different on different probes which I have not adjusted. Is this number generated automatically when you calibrate?

    thank you

    Yes, the offset is determined by the system when you calibrate the probe port.

    Remove the Set Off statement. See this sticky post for details about when to use a Set statement and when not to use one. https://forum.neptunesystems.com/sho...l=1#post114462
