I recently got my thermostat connected to my home automation system, and one of the things I did was log when the AC is turned on and turned off. When I looked at the logs, I was a bit surprised to see how frequently it was cycling. I've attached the past three hours or so from the log, but basically, it looks like it's runs for 10 minutes, then shuts off for 6 minutes, then runs for 10, then off for 6. Is that normal, or should there be longer cycle times? Obviously I'd like the system to run in the most energy efficient manner as well as create as little wear and tear on the system as possible.
Just for some background, this is my upstairs unit and the thermostat is set for 78 degrees. I'm in central FL and it was about 90 degrees outside during the time this log was taken.
Each line on the log lists the date and time the AC status changed. A 1 at the end of the line indicates it was turned on and a 0 indicates it was turned off.
