The ZTech 2 Zones HVAC Controller is an HVAC zone controller that operates multiple, independent comfort zones in your home using your standard gas/electric system. Zoning reduces energy use by not heating or cooling unused zones. The dual zone HVAC controller also improves comfort level within the home by allowing independent control of each zone's temperature. In addition, zoning improves your system's efficiency by satisfying heat/cool calls faster, and extends the HVAC system life reducing run times!
For two story homes, the thermal equalizer feature does away with the age-old problem of too much heat upstairs and too little downstairs, and provides for further energy savings by recycling the excess upstairs heat to the lower levels. This dual zone HVAC controller works great with standard non-power stealing single stage heat/cool thermostats or ZTech communicating thermostats controlled by X10 or serial RS232/485 systems. Easily installed and comes in a compact 6" x 8" x 1.5", one pound chassis.
