    Programming heater depending on RT differs from hardcoding

    Hi,

    I programmed my heater at the seasontable, like If Temp < RT+-0.1 Then ON.
    Then I noticed my heater was not turning on after reaching that trigger, but .2 points lower then that. It was doing the same at the opposite If Temp > RT+0.2 Then ON.

    Is there some delay in polling the Temp probe and comparing that value the seasontable data???

    Now I've changed the code back to hardcoded temps and now it works flawless....

    The season table transitions smoothly as the month passes. The set points are only for the first day if the month and then linearly interpolates for the other days of the month.
