LED Indicators
The LED indicators are used to indicate system activity. The AUX indicator illuminates during a call for second stage heating. The auxiliary stages are used to maintain comfort during extremes in weather conditions. If the AUX LED is illuminated too frequently during periods of moderate temper- ature, check the differential settings (page 5).
The CHECK indicator is used to monitor system status. If the CHECK indicator is illuminated, call your local HVAC service provider.
The EMER indicator is illuminated only when the system switch is moved to the EM, emergency heat position. The EM position is only used when the primary stage of heat is not functioning or requires service.
