BASIC OPERATION OF YOUR ZONED COMFORT CONTROL SYSTEM
Your Aprilaire Zoned Comfort System will allow you to increase your comfort by directing conditioned air to separate areas (zones) based upon each zones thermostat setting. To operate the system, just set or program each zones thermostat to your desired comfort and
When there is a heating or cooling call from any zone, the appropriate heating or cooling equipment will be turned on. The dampers in 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.
Aprilaire Zoned Comfort Control is a heat call priority system. This means that there are certain times when heating calls will take precedence over cooling calls. This occurs if two calls for opposing modes exist simultaneously while the system is idle, in which case the heat call will be satisfied first. In all other cases a
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.
The following sections describe how to make Heating, Cooling, and Emergency Heat calls as well as how your Aprilaire Intelligent Zoned Comfort Control System can control the other pieces of your HVAC system.
