1) Its saying 100% because it doesn't recognize a heat source to get it to the chosen temp under #2.. so its giving full power potential to outlet on Herpstat that a heat source would be plugged into. You can turn the Power percent down or lower the Factory setting Temp and that would change the percent of power to 0.
2) as far as 28%. Do you have the Power potential setting on full 100% power?
If you do the only reason you would be running at a low percent is because the Temp is up to 91/92 already and thats what Dimming (proportional ) does.. Its cuts down on power to regulate.
3) Ao/Io Ive never used.. Its on default.
Maybe one of the others can teach us something tonight about that Safety setting.
I use my HI/LO alarms but dont know about AO/IO.
