To operate this system, just set or program each zones 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 zones thermostat. However, due to the open design of todays 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.

Models 6202 & 6203: These two models were designed to work with your singlestage heat/cool equipment (for example a furnace and an air conditioner). The 6202 is for two zones while the 6203 is for three.
