ANNUNCIATION

Figure 26 Annunciation Page

The annunciation page shows the status of the load control input (call for heat), pre-ignition interlock (proof of gas valve closure), and the running interlock strings. The components are listed in the order they are wired. This page can be called up at any time from the operation page (Figure 25). This page is very helpful for troubleshooting a lockout 67 (ILK off). All components for a given string are wired in series. The first component that indicates off will be the safety device to check.
