have to reprogram the thermostat. However, if
the display is blank, the batteries are dead or

Although the thermostat has a low battery
indicator, replace the batteries once a year to
prevent the thermostat and heating/cooling
system from shutting down due to lack of
battery power.
When leaving home for longer than a month,
as a precaution, change batteries before you
leave to prevent system from shutting down due
to lack of battery power.
