Information

Thermostat controls

Fan Switch is used to
control your fan.
In "Auto" mode, the
fan runs only when the
heating or cooling system
is on.
If set to "On," the fan runs
continuously

Battery replacement

Install fresh batteries when the REPLACE BATT warning begins
flashing, once a year, or before leaving home for more than
a month. The warning flashes about two months before the
batteries are depleted.
Batteries provide backup power to the display during power
interruptions if your thermostat was wired to run on AC power
when installed. All settings are permanently stored in memory,
and do not require battery power.

If "Heat On" or "Cool On" is
flashing, compressor protection
is engaged.

Built-in compressor protection

This feature helps prevent
damage to the compressor in
your air conditioning or heat
pump system.
Damage can occur if the
compressor is restarted too
soon after shutdown. This
feature forces the compressor
to wait 5 minutes before
restarting.
During the wait time, the
display will flash the message
Cool On (or Heat On if you
have a heat pump). When the
safe wait time has elapsed,
the message stops flashing
and the compressor turns on.
