When my furnace first fires up in the morning it starts out in 'recovery' and on high fire even if the thermostat set temperature is only a few degrees warmer than my home's current temperature. My stat is a HW VisionPro IAQ. Is this the way it should operate? It was my understanding that high fire would only be needed on the coldest days. Is the stat communicating properly with the furnace or is there a way to adjust the stat to only use high fire when there is a large gap between stat set temp and current home temp?
