About a month ago, I got an alert notification that my Energy Sentinel was out of programed parameters. I was on the road and was unable to check the site to see what the temperature was so I called my son-in-law who checked it and told me that it registered 46 degrees. This temperature being lower than my 58 degree alert point, I placed a called to a neighbor to see if the community had lost power. I was told that everything was normal and that I probably had a failed monitoring device.
He volunteered to check it out. He promptly returned my call to tell me that it was indeed quite cold in the house and that I had no information displayed on the LED readout on my furnace thermostat. We did have power in the house as the other electric appliances seemed to be working properly. I immediately cancelled my afternoon schedule and began my 3 1/2 hour drive to our home.
Upon arrival, the inside temperature was about 42 degrees. It was forecast to continue a very cold weather pattern with expected temperature to go below zero degrees Fahrenheit. It was now about 6:00 pm and I made a call to an after hours service company for an emergency service call. Just in case, I made a trip to a local hardware store and purchased 6 small space heaters. The service folks saved the day as they were able to correct a blown out transformer that sent power to my inside controller.
There is no doubt in my mind that if I hadn't responded to the Energy Sentinels warning transmission, that my home would have completely frozen up due to the failure of this simple part in the furnace system causing many thousands of dollars damage. I can think of no reason that all persons living is cold weather areas should not have an Energy Sentinel in their homes. This one occurrence has paid for the monthly cost FOREVER. That night, the temperature dropped to 13 degrees below zero!
Thanks for your GREAT service! Phil
