By the way, the thermostat must have a sensor, where is it located? As when the sensor sense that the temperature reached what I've set, it will stop, isn't it?
Closing vents, is not going to reduce the volume of the house. What happens, is when you close vents, the system has to work harder to pull air through the cold air returns up on the second floor, so that the heat or ac will keep the environment equal. The thermostat sensor is in the thermostat.
Now, what you could do, which is a pricy investment up front, is go with something like the prilophix thermostat, that uses remote sensors, and you can monitor either through a third party site like ourhomespaces.com, or monitor at home. The main question is, how old is the hvac system, is it a 80%, 90 plus, does it have a heat pump, or conventional a/c.
Also, another thing you can do, is get a weather station that allows you to use remote sensors to measure humidity and temp throughout the house. Contact your utility to see if they do home energy audits. Our city owned charges $50 to do the audit. We just had a powered roof vent added, due to over the Summer, we would see attic temps up around 130, even though outside at the peak was around 94-96. It will defiantly make a difference next Summer, along with helping with running the a/c. They start running when the temp gets to 110, and shut off at 85, but helps overall.
