Battery Replacement - Honeywell PRO 2000 Serie Manual De Uso

Operating Manual

Battery replacement

NOTE: Batteries are optional (serving 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.
Most settings are stored in non-volatile (permanent) memory. Only the clock
and the day must be set if the thermostat was 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.
