I've read many of 52i owners run their Accentra in stove temp mode for a more even burn with less cycling when it's really cold. I have been burning mostly in room temp mode but did try a couple of times to switch modes. In each instance, room temps dropped about five degrees. I did adjust the dial to six but still couldn't get the room that warm. As soon as I switched back to temp mode, the room temp rose steadily back to its former comfortable level. I'm guessing that the ESP probe could be dirty but think I'll wait until it's warmer before pulling out the stove to check. Anyone else notice this?
