Pro1 T771 Installation manual - Manual (Page 3)

Important:
The low battery indicator is displayed when
the AA battery power is low. If the user fails to
replace the battery within 21 days, the
thermostat display will only show the low
battery indicator as a final warning before the
thermostat becomes inoperable.
NOTE: In applications where the
thermostat will see temperatures below 40
degrees it is recommended that 1.5V AA
lithium batteries be used instead of alkaline for
increased battery life. (Extreme temperatures
decrease the life of Alkaline batteries.)
