Power Outages - Honeywell Programmable Thermostat Owner's Manual

POWER OUTAGES

Backup batteries will hold the pro-
gramming and keep the display on
during most power outages. Once
the power is restored, the system
will resume normal operation.
If the display goes off when power
is lost, either the backup batteries
need to be replaced or are not
installed. When power is restored,
the display will flash 1:00 PM to
remind you to reprogram.
