1 If wires will be connected to both RC and R on the new thermostat, remove
metal jumper wire between RC and R. Leave metal jumper wire in place if only
one of the terminals, RC or R, will be connected on the new thermostat.
2 If wires were connected to both R and RH terminals on the old thermostat,
remove metal jumper wire between RC and R on the new thermostat. Connect the
old R to the new RC and the old RH to the new R.
3 If two C and/or C1 wires were connected to the old thermostat, do not
connect them to the new thermostat. Wrap the bare end of each wire separately
with electrical tape and do not use.
4 If one C and/or C1 wire was connected to the old thermostat, the wire should
be connected to the “C” letter designation on the new thermostat.

modification is required. Call your local heating and cooling contractor for
assistance.
3 If the old thermostat had wires on both O and B, be sure to attach the B
wire to the C letter designation on the new thermostat. If another wire is
already matched to the C, contact Honeywell.
4 If the old thermostat had wires on W1, Y1 and W2, some system modification
is required. Call your local heating and cooling contractor for assistance.

Understand Temperature Recovery Feature
Your thermostat comes with a feature called Adaptive Intelligent RecoveryTM,
which eliminates all guesswork when setting your schedule. How long does it
take the furnace to warm your house in the morning before you get out of bed
or how long does it take the air conditioner to cool your house in the
afternoon before you return from work? No problem. The thermostat determines
that for you.
Simply set your program schedule to the time you want the house to be at your
comfort temperature. The thermostat then turns on the heating or cooling at
just the right time to have your home reach your scheduled temperature at your
scheduled time.
For example–you get out of bed at 6:00 AM and want the temperature to be 70°F.
Set the Wake period for 6:00 AM and 70°F. The thermostat then turns on the
heat before 6:00 AM to raise the temperature to 70°F by 6:00 AM.
The thermostat alerts that the heating or cooling system is coming on before a
scheduled time when “Recovery” shows on the screen.

It takes about a week for the thermostat to adjust to local weather, your schedule, the construction of your home and your heating and/or cooling system. Each day it adjusts the next day’s recovery start time accordingly.

Review Battery Tips
1. Replace the batteries as soon as LO Batt flashes in the display. The LO
Battery indicator flashes in the display one month before the batteries run
down completely.
2. Always use fresh AA alkaline batteries. Non-alkaline batteries do not last
as long and can leak, causing thermostat damage.
3. Although the thermostat has a Low Battery indicator, replace the batteries
once a year to prevent the thermostat and heating/cooling system from shutting
down due to lack of battery power.
4. As a precaution, replace the batteries when leaving your home for more
than a month to prevent your heating/cooling system from shutting down if the
batteries run down completely.
