| Each Room Thermostat controls the amount of air conditioning needed to maintain the users temperature settings in that area of the home. Other Thermostats control independently in other areas, all off of the same air conditioning system. The system automatically shifts from high to low speed modes as needed to satisfy all zones. |

| This 2 Zone Installation controls a 2-Stage Air Conditioning System that serves two separate areas of the same office. |
| When both thermostats require the system to operate in cooling mode, both zone dampers open and the system operates in high speed. |
| When only one thermostat requires the system to operate in cooling mode, only one damper opens and the system runs in low speed. Each separate space temperature is maintained independently ; system capacity is varied proportionally. |
