What is the HFT (ooops, I mean HLF) setting normally on from the factory? Mine is at 0. I remember that last year in the LL forum it was suggested that we change the setting to 1 to help with temp response. What I don't know is if that is up from 0 to 1, or down from some other number to 1. Seems like it's taking too long for temp to go from 69 to 70. Day setting for 70 is at 6:15 a.m. At 6:15 this a.m., temp was 69. At 8:45, it was still 69. Finally reached 70 degrees at 9:00 a.m., so 2 hrs. 45 min. to come up one degree? We have a Hyfire II and it's certainly not cold enough to light the 2nd burner yet, it was 31 earlier and it is now 39! Upstairs house is only 1600 sf, so not overly large either. Hyfire II is overkill for our house.
Also, will changing HLF up to 1 affect the FR? We had to lower ours to 32 to prevent hot coals from dumping into ash pan. After speaking with Neil a few nights ago, we tried changing it back up to 40 last evening. This morning we have burning coals at the very edge of the grate, so I've lowered FR down to 35.
Also, we're still having the temperature drop down to 67 overnight, even though temp is set for 69. This did not happen for most of last heating season, when our temps were maintained perfectly, UNTIL the end of the heating season, when we began having 67 overnight. I'm keeping a log as Neil suggested, and so far, we've had a.m. temp of 67 with FR 36, outside temp 31, 68 with FR 0 with outside temp of 42, 68 with FR 11, outside temp 42. Yesterday we had temp of 69 at 5:10 a.m., FR 16, and outside temp 42. At 7:05 a.m., it was 69, FR 26, outside temp 42. The NIGHT setting of 69 degrees is for 8 PM, so the temp is dropping from that time on, until the a.m., when the DAY setting takes over at 6:15 a.m. Neil offered to swap our thermostat for another during our conversation; I think it may be necessary.
Just an aside -- while the Coal-trol temp is displayed, for instance this a.m., when it read 69, our Carrier thermostat, only 2 inches away on the same wall, read 67. And the house definitely felt like 67, not 69. However, both the Coal-trol and Carrier thermostats used to read EXACTLY THE SAME temps. Last year when the 67 degree readings began is when the difference in readings began as well. Now Carrier thermostat ALWAYS reads 1 or 2 degrees lower than Coal-trol thermostat.
