I had to tell our kids recently that they were going to be grounded if they kept messing with the control unit! They helped & said that it was so blazing tepid all the time with the settings I favorite. I thought 75 degrees was a adequate setting, however they didn’t seem to guess so. They complained that it was hard to learn for school with it being so tepid all the time. They also made a enjoyable point that heat rises, & since their rooms happen to be upstairs, they get the bulk of the heat. When I went up to their rooms & they showed me just how overheated it was, I had to agree that it was pretty tepid upstairs. I guess I didn’t realize this because I rarely go up there, however yup it was rather sizzling up there so I could absolutely see their point. I decided to buy each of our kids a window air conditioning system component to resolve this problem. When every one of us had all the window air conditioning system units installed, they were absolutely triumphant with the change. They no longer had so much trouble learning & doing homework. I never had to worry about the control component being changed any longer & it seemed that everybody was happy with the changes. The energy bills of course spiked a little bit & I would have to ask our kids if they were shutting off their air conditioning system machines when they weren’t in their rooms. I told them that if they didn’t shut them off when they left their rooms, they would have to pay for the electric bills.
