I am trying to see if anyone else who has installed, one or more, Elk M1ZTSR is experiencing accuracy problems when seasons change from summer to winter. Both of my sensors (outside and attic) are not accurate when sensing at opposite ends of the temperature range. I can recalibrate them, but then when the temperature returns back in the opposite direction, then the delta is significantly large. I have use both a laser temperature sensor and Oregon Scientific remote probes to verify the discrepancy. I remember this topic being discussed before, and I found a few postings. But I did not see a large number of confirmation about the "temperature slope" problem.
