INSTALLATION TIPS
Wall locations
Thethermostatshouldbeinstalledapproximately4to5feetabovetheoor.
Select an area with average temperature and good air circulation.
Do not install thermostat in locations:
• Close to hot or cold air ducts
• That are in direct sunlight
• With an outside wall behind the thermostat
• In areas that do not require heating and/or cooling
• Where there are dead spots or drafts (in corners or behind doors)
• Where there might be concealed chimneys or pipes
Tip
Pick an installation location that is easy for the user to access. The temperature of the location
should be representative of the building.

Alternate Wiring (Conventional Systems)
If labels do not match letters on the thermostat, check the chart below and connect to terminal as shown
here (See notes, below).
If wires will be connected to both RC and RH/R terminals, remove metal jumper.
If Cor Xwire is available then you can connect with Cterminal. If there is no Cor X
wire then no need to connect with C terminal.
If you have a heat pump without auxiliary/backup heat connect Oor B, not both. If you do
not have a heat pump, do not connect B. Wrap bare end of wire with electrical tape.
Place a jumper (piece of wire) between Yand Wif you are using a heat pump without
auxiliary/backup heat.

Caution: Electrical Hazard
Failure to disconnect the power
before beginning to install this
product can cause electrical
shock or equipment damage.
Warning:
All components of the control
system and the thermostat
installation must conform to
Class II circuits per the NEC Code.
1. If you are replacing a thermostat, make
note of the terminal connections on the
thermostat that is being replaced. In some
cases the wiring connections will not be
color coded. For example, the green wire
may not be connected to the Gterminal.
2. Loosen the terminal block screws. Insert
wires then retighten terminal block screws.

Tips:
RH & RC terminals
For single transformer systems, leave the jumper wire in
place between RH and RC. Remove jumper wire for two
transformer systems.
Heat pump systems (With No AUX or
Emergency Heat)
If wiring to a heat pump, use a small piece of wire
(not supplied) to connect terminals W and Y.
C terminal
The C (common wire) terminal does not
have to be connected when the
thermostat is powered by batteries.
Wire specications
Use shielded or non-shielded 18-22 gauge
thermostat wire.

This feature will flash FILT in the
display after the elapsed run time
to remind the user to change the
filter. A setting of OFF will disable
this feature.
This feature allows the installer
to change the calibration of the
room temperature display. For
example, if the thermostat reads
70° and you would like it to read
72° then select +2.
This feature allows the installer
to select the minimum run
time for the compressor. For
example: A setting of 4 will force
the compressor to run for at
least 4 minutes every time the
compressor turns on, regardless of
the room temperature.
You can adjust the filter change
reminder from OFF to 2000
hours of run time in 50 hour
increments.Tap the second
button from the top left side of
the thermostat to display the
current filter elapsed run time.
You can adjust the room
temperature display to read
3° above or below the factory
calibrated reading.
You can select the minimum
compressor run time from OFF,
3, 4, or 5 minutes. If 3, 4 or 5 is
selected, the compressor will
run for at least the selected
time before turning off.

The compressor short cycle delay
protects the compressor from
short cycling. This feature will not
allow the compressor to be turned
on for 5 minutes after it was last
turned off.
The differential setting, often
called cycle rate or anticipation,
is adjustable. A smaller differential
setting will cause more frequent
cycles and a larger differential
setting will cause fewer cycles.
The differential setting often
called cycle rate or anticipation, is
adjustable. A smaller differential
setting will cause more frequent
cycles and a larger differential
setting will cause fewer cycles.
Selecting ON will not allow the
compressor to be turned on for
5 minutes after the last time the
compressor was on. Select OFF to
remove this delay.
The cooling differential setting
is adjustable from 0.2° to 2°. For
example: A differential setting
of 0.5° will turn the cooling on
at approximately 0.5° above the
setpoint and turn the cooling off
at approximately 0.5° below the
setpoint.
The heating differential setting is
adjustable from + 0.2° to + 2°.
For example: A differential setting
of 0.5° will turn the heating on
at approximately 0.5° below the
setpoint and turn the heating off
at approximately 0.5° above the
setpoint.
