I installed the humidifier on the supply plenum and digital guage on return as instructions showed.
I have a furnace that draws outside air into the return duct. This is a new construction home and is pretty air tight. Will the outside air coming in effect the rh reading?
Is there a special configuration for this? I connected the thermostat g wire to the digital meter g wire as instructed.. everything works fine, just the rh is higher than i imagined and i don't think my thermostat does anything with humidity.. maybe i need to upgrade the thermostat?
