From a previous thread I posted, it was recommended I switch my old mercury for a digital 'stat. This I did, and I set the cooling CPH to 2. I guess the question is - how does the CPH really work? I have the honeywell RT2310B, which I don't think has that "auto learn" feature some other stats do.. so does that mean I'm supposed to get 2 cycles per hour max? Approximately 2 cycles per hour? Is it normal to get about 4 cycles anyway (I'm supposing this is possible), depending on outside temps and insulation?
