Low Battery Warning - Hunter 42177 Owner's Manual

Operation

Low Battery Warning

Your thermostat has a two-stage low battery warning system.
When the batteries are first detected to be weak, the first stage
low battery warning is indicated by battery symbol flashing
on the LCD display. At your earliest convenience, you need to
replace the batteries with 2 new AA alkaline batteries.
When the batteries become too weak for normal operation,
the thermostat enters the second stage low battery warning
which shuts down the thermostat. In this condition, "BATT"
flashes alone on the display, and the thermostat will turn your
system Off. Your system will remain shut-off until the batteries
are replaced.
Note:
The thermostat will still keep the current Set Temperature and Filter
run time in memory until new batteries are installed. After confirming that new
batteries have been inserted, the thermostat will return to normal operation.
