Warning Description

The voltage input that feeds the CCR is lower than expected. This alarm defaults at 5% under nominal input voltage. When the CCR determines a warning or setpoint alarm, it will engage the indicator light and the warning will be shown on line 1 of the CCR display. The CCR will continue to operate in the event of a warning. Although the CCR will continue operating, warning conditions must still be noted and fixed. Allowing the CCR to operate in a warning state may cause problems for efficiency, general safety, and longevity of equipment.

Attempt to Correct

Always maintain safe working conditions by using appropriate personal protective equipment (PPE) where necessary.
Check the input voltage calibration: refer to How to Determine if Recalibration is Needed.
If the calibration is correct, consult an electrician to diagnose building power problems.
