During last month’s furnace tune-up, my partner & I thought it would be great to purchase an up-to-date thermostat for our residence. Our outdated thermostat was an outdated dial machine, & all of us could barely see the numbers anymore. Our furnace professional helped us to find a nice digital thermostat, which included a touch screen display. The furnace worker installed the thermostat while he was at our residence… He carefully instructed us how to use the up-to-date digital thermostat… Around 8 that night, the temperature in our lake residence drastically changed. My partner & I went out to look at the thermostat, & the temperature had changed to 68 degrees. The two of us tried to adjust the thermostat back to 71 degrees, but it kept reverting to 68 after a little while. The two of us gave up & decided to contact our Heating, Ventilation, & A/C carrier early on in the morning. When all of us woke up, the thermostat was 71 once more. My partner & I could not even understand the problem, so all of us made an appointment to discuss the different thermostat concerns. When my partner contacted the Heating, Ventilation, & A/C corporation, they immediately realized what was going on with our machine. Our up-to-date thermostat was programmable, & all of us needed to change the settings to make it work correctly. The thermostat was set up to change the indoor temperature at 8 p.m. As soon as my partner & I came to the realization that the thermostat needed to be programmed, all of us got out the handbook & made the necessary changes. Our programmable thermostat has numerous temperature settings. The bunch of us can change the climate during the morning, afternoon, & evenings. The bunch of us decided to make them all the same, so we didn’t have to deal with any confusion.
