My son just ran to me telling me that the light went black so he turned it back on! I asked him to show me what he did and he twisted my finger. He then showed me which direction he turned it. INCREASE!1 Then temp was already rising so I turned the stat until it shut off. It then immediately came back on so I turned it a bit more. I know what I am going to be doing every second of the next twelve hours!!!! Watching my temp and praying!!!!! Poor thing! I think I scared him a bit by my reaction. He was so excited that we were hearing a peep and he wanted to help. Thankfully I was able to get myself together before I upset him. We had a big discussion on what that light was for! I told the kids that not even their Daddy has permission to touch that thermostat!
