Air Conditioning Zoning

Separate Room Thermostats control Motorized

Zone Dampers and Air Conditioning System

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.

ZONE 1

ZONE 2

Damper 1

Damper 2

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.
