I just installed a NOMA 7-Day programmable thermostat, and I have a question. When I first installed the thermostat, it stated the humidity in my house at 18%. I need it to be around 35-40% so I increased the setting. It is now a full day later, and the only reading that I can get for humidity states "L0%". What does this mean? The icon shows that the humidifier is activated, but I am wondering what the "L0% is referring to. Is it working? Why does it not give a % value?
