BATTERY REPLACEMENT
NOTE: New batteries must be replaced within one minute after removal of
old batteries. If more than one minute elapses the programmed settings will
be lost and revert to the factory settings. See Figures 3 and 4 for cover
removal and battery orientation.
Replace batteries once per year or when “LOW BATTERY” appears on the
display. This will keep the thermostat working properly. Replace with two
new AA alkaline batteries.
