Screen Icon Description
+
Red flame with a plus indicates the system is running in emergency heat mode.
Transitioning to next schedule temperature setting. This icon will only appear if
smooth setback recovery is enabled under the installer setup. When enabled, it
will begin recovery up to two hours before the programmed time so that the pro­
grammed temperature is reached at the corresponding programmed event time.
Assume 12°F per hour for gas/electric heating and 6°F per hour for first stage
compressor based cooling. When smooth set back recovery is disabled, the
control will start recovery at the programmed time set in the schedule.
