Can I create zones for my HVAC?
I have a ranch house, with a terrace (basement) level below. The thermostat for the HVAC is on the main floor. There is one furnace with a heat pump outside. Its a 3-ton, I believe. In the winter, the terrace level gets very cold and in the summer the upper level gets very warm.
Is there a way that I can add some gizmo to make the heating/cooling smarter? A zone system of some sort?
