STEP 2. REMOVE OLD THERMOSTAT
❑ Test
y
our heatin
g
and coolin
g
s
y
stems to make sure the
y
work properl
y
. If either s
y
stem does not work, contact
y
our local heatin
g
/air-conditionin
g
dealer. To avoid compressor dama
g
e, do not operate the coolin
g
s
y
stem when
outdoor temperature is below 50°F (10°C).
❑ Turn off power to the s
y
stem at the furnace or the fuse/circuit breaker panel.
❑ Carefull
y
unpack
y
our new thermostat and wallplate. Save packa
g
e of screws, instructions, and receipt.
❑ Remove the cover from the old thermostat. If the cover does not snap off when pulled firml
y
from the bottom, check
for a screw or screws used to lock on the cover.
❑ Loosen the screw or screws holdin
g
the thermostat to the wallplate and lift the thermostat awa
y
.
❑ Disconnect the wires from the old thermostat. As
y
ou disconnect each wire, attach the enclosed labels with the old
terminal desi
g
nation. If there are onl
y
two wires, the
y
do not need to be labeled. Wrap the wires around a pencil as
shown to keep them from fallin
g
back into the wall.
Special Installations
Read this section if
y
ou are replacin
g
:
• Clock thermostat with separate wires for the clock.
• Thermostat with six or more wires connected to it.
• Thermostat in a heatin
g
onl
y
s
y
stem with three wires.
Replacing a Clock Thermostat that has C or C1 Clock Terminals
If
y
ou are replacin
g
a Hone
y
well Chronotherm®
Thermostat,
y
ou ma
y
find one or two wires
g
oin
g
to the C or C1 clock
terminals on the Chronotherm wirin
g
wallplate. Do
not
allow them to touch, or
y
ou can dama
g
e the transformer.
Disconnect the wires and wrap them separatel
y
usin
g
electrical tape. Do
not
wrap them to
g
ether. Place the wires
where the
y
will not interfere with the operation of the new thermostat. Record the colors and terminal desi
g
nation
labels of the remainin
g
wires.
Replacing a Thermostat that has Six or More Wires
If there are six or more wires (excludin
g
clock wires attached to terminals),
y
ou probabl
y
have a variation of a
multista
g
e heat pump or other multista
g
e s
y
stem. This thermostat is not compatible with multista
g
e s
y
stems, so return
the product to the place of purchase. For information about which pro
g
rammable thermostats will work with
y
our
s
y
stem, call Hone
y
well Customer Relations Center, at 1-800-468-1502.
Replacing a Thermostat that has Three Wires
If
y
ou have three wires for a heatin
g
onl
y
s
y
stem and can operate the fan usin
g
the fan ON switch this thermostat works
with
y
our s
y
stem. However, some hot water (zoned) heatin
g
s
y
stems also have three wires. Your thermostat will work
onl
y
if
y
ou install an isolatin
g
rela
y
on these s
y
stems. For details, call
y
our local heatin
g
and/or coolin
g
contractor.

STEP 3. MOUNT THERMOSTAT WALLPLATE
❑ Separate the wallplate from the thermostat b
y
placin
g
y
our thumb or fin
g
ers
between the bottom of the wallplate and the thermostat, and pullin
g
the
wallplate up and awa
y
from the thermostat. See illustration at ri
g
ht.
❑ Position the wallplate on the wall. Level the wallplate for appearance if desired.
Use a pencil to mark the two mountin
g
holes that best fit the application.
❑ Remove the wallplate from the wall. Drill two 3/16 in. holes in wall (if dr
y
wall) as
shown. For materials such as plaster or wood, drill 7/32 in. holes where marked.
Gentl
y
, tap the (provided) anchors into the drilled holes until the
y
are flush with
the wall.
❑ Reposition the wallplate over the holes. Pull the wires throu
g
h the wirin
g
openin
g
. Loosel
y
insert mountin
g
screws into each of the holes.
❑ Level the wallplate if desired. Thermostat functions properl
y
when not level.

STEP 4. WIRE WALLPLATE TERMINALS
IMPORTANT
All wiring must comply with local codes and ordinances. If
unsure about household wiring procedures, call your local heat-
ing/air-conditioning contractor.
Refer to the labels
y
ou placed on the wires when
y
ou removed the old
thermostat (see illustration).
❑ Match the letter of
y
our old thermostat wire with the correspondin
g
terminal letter on
y
our new thermostat. Refer to Table 2.
❑ Remove the factor
y
-installed jumper connectin
g
terminals R and RC if
wires are connected to both of those terminals.
❑ For wirin
g
dia
g
rams, if needed, see pp 21-22.
❑ Loosen the terminal screws. Slip each wire beneath its matchin
g
terminal. Wraparound and strai
g
ht connections are both acceptable,
(see illustration). Ti
g
hten the terminals.
❑ Plu

STEP 5. INSTALL THE BATTERIES
IMPORTANT
Three AA alkaline batteries are included with the thermo-
stat. Batteries must be installed for programming and opera-
tion of the thermostat and the heating/cooling system.
❑ Install the batteries in the wallplate so the positive terminals all
point up (see illustration).

When the batteries are runnin
g
low, a REPL BAT messa
g
e flashes for one to
two months before the batteries run out completel
y
. Replace the batteries as
soon as possible once the messa
g
e flashes.
IMPORTANT
Although the thermostat has a low battery indicator, replace the
batteries once per year to prevent leakage and to prevent the ther-
mostat and heating/cooling system from shutting down due to lack
of battery power in the thermostat.
If
y
ou insert new batteries within 20 to 30 seconds of removin
g
the old
batteries, the s
y
stem retains the current time and da
y
. If the displa
y
is blank,
the batteries are dead or installed incorrectl
y
. You must reset the time and
da
y
. Refer to Set the Clock for instructions.
As a precaution when leavin
g
home for lon
g
er than a month, chan
g
e batteries before leavin
g
to prevent
the s
y
stem from shuttin
g
down due to lack of power. Alwa
y
s use fresh alkaline batteries. Nonalkaline
batteries do not last as lon

. The
