Ok guys/gals, installed my 10-CPM this past fall and have had absolutely 0 problems until the last 3 weeks or so. I'm having a problem that I couldn't seem to find any threads on in the forum. So here goes it, i have the englander hooked up to a skytech wirless thermostat that is programmed to run at 70 while I'm home then drop to 65 at night then ramp back to 70 slowly during the day. This has been working great for about 3mons now with no issues, but about 3 weeks ago I noticed that while the t-stat is set at 70 the actual temp may fall to like 66 or 67 and seems to stay that way for way to long before the flame builds back up then eventually gets the temp back to 70. Then it will drop back again. Basically the temp isn't staying consistent. It seems like the reaction time between the t-stat and the stove is off. Is this possible or could it be some other issue? Just to fill you guys in: 10 CPM, running on Skytech wirless(in hi/low mode), settings at 1-3-1, just started 4th ton, clean regularly, I have not changed anything and problem just started about 3weeks ago. Also t-stat is only set for a 1degree swing and temp here in Ohio has been averaging in the teens and low 20's for sometime now with no prior issues. Any suggestions welcome. Thanks
