Had the honeywell for a couple years--- works great, but with no swing the stove was cycling too much. Time to upgrade to one with a swing. Bought a Lux 1500 with swing on a reco fro the board here in a few sigs/etc. Seemed to be a good unit for the money. Well, i'm completely unimpressed with this thing..... Here they are side by side sitting on the coffee table for about 1 hr with no one touching them or being near them. It got down to 61 deg in the room before the thing read 68 and fired on the stove. The honey well matches the oil big thermo on the wall FYI, and i assure you it was 61 because it was COLD in here. "Factory calibrated" my a$$. Another PO'ed night with my F'ing stove. See? potty mouth is kicked in again. I blew up at my gf for no reason after working on this damn thing too. UGH. Why don't I just ever learn and leave well enough alone because eveyr time i try to do something to improve life, I just make it worse?
