Finally got new hvac installed (American Standard - gas) after original finally gave out. Our new one came with a humidifier attached to the furnace. There is a thermostat setting on the humidifier itself and you can also set it with the wifi thermostat upstairs in the hallway. So do I set one of them? Both of them? Set the one on the humidifier on max, then adjust it with the main thermostat? Appreciative of any suggestions!
