Battery replacement

Install two fresh AAA batteries when 

 flashes on the screen. Lo 

 appears for 60 days before the 

batteries are depleted.
Replace batteries once a year, or 

when you will be away for more than a 

month.
Most settings are stored in non-volatile 

(permanent) memory. Only the clock 

and the day must be set after you 

replace the batteries.

Turn thermostat over, 

insert fresh AAA 

alkaline batteries, then 

reinstall thermostat.

Set the System switch to Off before removing 

the batteries. Otherwise, the heating/cooling 

system could remain activated even when 

batteries are removed.
