How do I determine the humidity level in my home?
I am trying to solve a dust problem and am considering a whole house dehumidifier. I don't have musty odors, sweating windows, or mold.
How can I determine, though some sort of measuring device, the relative humidity, and if I need a dehumidifier or a humidifier?
Humidifier control and HRV control don't match each others RH readings
I'm not really sure how to approach this problem, my humidifier control shows my RH in the house is around 30% but the dial on my HRV control clicks in at around 60% RH. I live in Saskatchewan, Canada and the outside temp is hovering between 0C and -15C. I'm going to go out and get a hygrometer so I can get an idea which control is out, but I'm not sure what I should do after that? Is it possible to calibrate these controllers (I know, I didn't give any deal which controllers/units I have but I'm at work and don't have access to that right now). The controller for my HRV has 4 modes (off, constant, intermittent and circulate) and a dial for the RH. My humidifier only has a dial for the RH. I doubt these are set correctly and don't really understand the logic if one fighting another, etc. I have my humidifier set to 30% (it hasn't ever cut in IIFC) and the HRV doesn't ever run unless I set it to something other than off, but I'm not really sure where the RH dial comes in on the HRV controller. Thoughts?
