The zone control system

If you’re a homeowner, you’ve probably experienced rooms in your home that are consistently too hot or too cold. You also want relief from energy bills which get higher and higher each month. A common solution to both problems is zoning.
The zone control system allows a single HVAC unit to have separate temperature zones in the house. Each zone is controlled by its own space thermostat and motorized zone damper. If any of the zone thermostats call for heating or cooling, the zones not calling will have their dampers powered closed, and the zone(s) calling will have its (their) damper(s) remain open. The heating or cooling equipment will also be brought on at the same time. When all zone thermostats are satisfied, the heating or cooling equipment turns off and all zone dampers return to the open position to allow for continuous air circulation.
For additional energy savings, the homeowner should use programmable thermostats. Programmable thermostats will allow each zone to set back (this means maintaining a cooler temperature for heating) or set up (this means maintaining a warmer temperature for cooling). As an example, the bedrooms will only be conditioned at night, while the living space (kitchen, family room, etc.) is turned off. During the day, the living space is conditioned while the bedrooms are turned off. This method of "setting back" and "setting up" with zone control can save the homeowner as much as 30% on their fuel bills. |
