Someone probably replaced the OEM tstat with a aftermarket home type and just used the lo fan as the return to the furnace because they did not know how to wire it. If original, then someone has miswired it. Doug
After reading the post again, IF that tstat does NOT operate the roof AC at all, then that Tstat is aftermarket and is not wired correctly. Does the wall tstat state HEAT and COOL? A COOL only tstat the temp thermistor or bi metal spring is wired/coiled in reverse than for a HEAT(furnace Tstat) only tstat. The OP needs to state what Brand is listed on that wall tstat.
