Honeywell PRO 1000 Series Heat Pump Thermostat Instruction Manual
Operating Manual
Battery replacement
NOTE: Batteries are optional (and serve as backup power) only if your
thermostat is connected to 24 VAC.
Set the System switch to Off before removing the batteries.
Otherwise, the heating/cooling system could remain activated
even when batteries are removed.
Install two fresh AAA batteries when Lo Batt (low batteries) flashes on
the screen. The message 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.
The settings are stored in non-volatile (permanent) memory and are
thus preserved when the thermostat is without AC power or batteries.
NOTE: The low-battery icon will not appear when the batteries are depleted
if the thermostat is connected to 24 VAC.
