Newbie question about Delat-T

Hi, just installed my Tempest and it seems to be working well. I do have one question that I can’t find an answer to, What is the Delta-T. I know it is change over time but do we know what the parameters are? What is the timeframe? That sort of thing. Thank you for any information on this.
