When the Heating, Ventilation & A/C company asked about a new temperature control to go with our new Heating, Ventilation & A/C system, I thought it was a great idea. They told me I could get a smart temperature control as part of the Heating, Ventilation & A/C package, and it would not cost anything extra. They input PC numbers for the Heating, Ventilation & A/C dealer, our hubby’s cell PC, and our cell PC. They also pre-programmed the number for the police station. The Heating, Ventilation & A/C specialist showed our hubby how to use the app that connected our cell PCs and main kindle to the smart temperature control. I thought working the temperature control was going to be super straight-forward, even though I was wrong. I hated the temperature control after only a week. I would program the air conditioning to turn on at 10 AM and turn off at midnight. I had the temperature set for seventy-two! Every day I had had to reprogram the temperature control. It was shutting off and on at odd sevenths, and the temperature was dropping down to sixty-eight. That was entirely too cool when I was the only a single in the house. I called the Heating, Ventilation & A/C company and told them I had a problem with the air conditioning unit, or the temperature control. I wasn’t sure which. I told them exactly what was happening. They told me it was the temperature control and someone would be at the lake house shortly. When the Heating, Ventilation & A/C specialist arrived, he had to fiddle with the temperature control and make it so it responded only to the commands coming from our cell PCs and kindle, and not from anyone who had the same model temperature control.
