When batteries are first installed, the display
will flash 1:00 PM and 32°. When the batteries are
low, the display will flash REPL BAT. You have 20-
30 seconds to replace batteries after removing them
from the thermostat. After 20-30 seconds, you will
have to reprogram. REPL BAT indication will disap-
pear when the thermostat is mounted back onto the
powered subbase.
If batteries are completely dead, the display
will go blank when the thermostat is removed from
the subbase. After replacing the battery in this
case, reprogramming is necessary.
