Hello, we had a lovely Mendota Fullview 44i gas insert installed last week, and it's worked perfectly until now. We have kept it in "smart" mode, which is when the unit turns on and off and raises and lowers the flame according to the temperature you set for the room on the remote. For the last day, the unit has turned on when the room temp is below the set temp on the remote (which is what it's supposed to do), but the flame stays high even when the room temp is close to the set temp. It also doesn't turn off even when the room temp is above what we've programmed into the remote. The remote has a low-battery indicator but it's not showing that the batteries are low (and they shouldn't be, they were just installed a week ago). Any ideas?
