air conditioner). The 6202 is for two zones while the 6203 is
for three.

Basic Operation
Your Aprilaire Zoned Comfort Control System will allow you to
increase your comfort by directing conditioned air to separate
areas (zones) based on each zone’s thermostat setting.
To operate this system, just set or program each zone’s
thermostat to your desired comfort set points. When there is a
heating or cooling call from any zone, the appropriate heating
or cooling equipment will be turned on. The dampers to zones
not requiring heating or cooling will close and the conditioned
air will be directed to the calling zone (s) until the thermostat
is satisfied.

If one zone is calling for heat, while another zone is calling for
cooling during the minimum off time between cycles, the heat
call will be satisfied first. After the heat call is satisfied, the
cooling call will be satisfied. There is also a 20 minute change
over feature which provides a maximum call time of 20
minutes if opposing calls exist. The heating and cooling
equipment will not operate at the same time.

Your zone control system is designed to direct conditioned air
only to the rooms served by that zone’s thermostat. However,
due to the open design of today’s homes, it may not be
possible to maintain drastic temperature differences between
zones. Closing interior doors is a good way to reduce the air
exchange between zones and increase the temperature
difference between them.
