Abstract

A zone control panel that is easy and intuitive to use and to program. In some embodiments, a zone control panel may be configured to have an easy to use, single level menu structure with, for example, a configuration mode and/or a checkout mode. The configuration mode may, if present, include a number of menu screens sometimes without any sub-menu levels. Likewise, the checkout mode may, if present, include a number of menu screens sometimes without any sub-menu levels. A mode selector may be provided to select a particular mode, after which, the menu screens that correspond to the selected mode may be sequentially displayed to the user. Other features and aspects are also disclosed.
