I have had an aged temperature control in my condo for several years.
And for some reason I just never got rid of this thing.
It was one of those plastic temperature controls on the wall with a slider that was plastic. When the aged plastic temperature control to my central heating plus a/c plan finally broke down it was not a pretty thing! It was the dead freezing of the Winter. And I had my heating on. Well, when I went to adjust the temperature control on the wall the slider broke off. And then what happened was my temperature control was stuck pumping out all of this heating! It was so bad it nearly hot the house. I had to go down to my basement plus pull the fuse on the circuit that ran the central heating plus a/c plan unit. That was the only way to get my central heating plus a/c component to finally shut down! I then opened several windows plus doors in the house, plus this cooled everything down. When I called the local heating plus a/c contractor, the certified heating plus a/c specialist was kind of shocked that I still had one of these aged slider plastic temperature controls. He gave to sell me either a digital temperature control plus a programmable smart temperature control. I chose to go with a smart programmable temperature control. I had heard so much about these things in terms of saving on energy use that I really wanted to try one out!
