INSTALLATION
Step 1 -- Thermostat Location
Thermostat should be mounted:
• Approximately 5 fl (1.5 m) from floor.
• Close to or in a frequently used room, preferably on an
inside partitioning wall.
• On a section of wall without pipes or ductwork.
Thermostat should NOT be mounted:
• Close to a window, on an outside wall, or next to a door
leading to the outside.
• Exposed to direct light and heat from a lamp, sun, fire-
place, or other temperature-radiating object which may
cause a false reading.
• Close to or in direct airflow from supply registers and
return-air grilles.
In areas with poor air circulation, such as behind a door or
in an alcove.
Step 2 -- Select Model
P274-0100-C (l-stage cool, l-stage heat) is to be used for
single-stage heating and/or cooling applications only. It
CANNOT be used with optional outdoor temperature sensol:
(See Table 1.)
P274-0200-C (l-stage cool, 2-stage heat) can be used with a
single-speed heat pump (HP), or tin air conditioner (AC) with a
2-stage furnace or fan coil. When using the thermostat
softwme (Configuration mode) select Option 5, HP/AC con-
figuration. This thermostat comes configured from the factory
as a heat pump thermostat. Select AC in Option 5 for AC oper-
ation. When AC operation is selected, the O/W2 terminal is
converted from a reversing valve output (O) to a second-stage
heat output (W2). This output can be used to control 2-stage
furnaces or 2-stage electric heat in fan coils. (See Table 1.)
P274-0300-C is for 2-speed compressor systems only (HP and
AC). Output YI controls compressor low speed and output
Y/Y2 controls compressor high speed. (See Table 1.)
Step 3 -- Install Thermostat
c. As each wire is disconnected, record wire color
and terminal marking.
d. Discard or recycle old thermostat.
NOTE: Mercury is a hazardous waste and MUST be dis-
posed of properly.
3. Open thermostat (mounting base) to expose mounting
holes. The base can be removed to simplify mounting.
Snap apart carefully to separate mounting base from
remainder of thermostat.
NOTE: If thermostat will not separate, insert a small screw-
driver into top slots for ease of separation.
4. Route thermostat wires through large hole in mounting
base. Level mounting base against wall (for aesthetic
value only -- thermostat need not be leveled for
proper operation) and mark wall through 2 mounting
holes.
5. Drill two 3/lr,-in. mounting holes in wall where
marked.
6. Secure mounting base to wall with 2 anchors and
screws provided, (additional anchoring holes available
for more secure mounting if needed) making sure all
wires extend through hole in mounting base.
7. Adjust length and routing of each wire to reach proper
terminal and connector block on mounting base with
I/4 in. extra wire. Strip only 1/4 in. insulation from each
wire to prevent adjacent wires from shorting together
when connected.
8. Match and connect equipment wires to proper termi-
nals of the connector blocks. (See Table 1.)
ELECTRICAL OPERATION HAZARD
Failure to follow this caution may result in equipment dim-
age or improper operation.
hnproper winng or installation may dmnage the therlno-
stat. Check to make sure wiring is correct before proceed-
ing with installation or turning on unit.
ELECTRICAL SHOCK HAZARD
Failure to follow this wmning could result in personal
injury or death.
Before installing thermostat, turn off all power to unit.
There may be more than 1 power disconnect.
I.
2.
Turn OFF all power to unit.
If an existing thermostat is being replaced:
a. Remove existing thermostat from wall.
b. Disconnect wires from existing thermostat, one at
a time. Be careful not to allow wires to fall back
into the wall.
9. Push any excess wire into wall and against mounting
base. Seal hole in wall to prevent air leaks. Leaks can
affect operation.
10. Snap case back together.
11. Close thermostat assembly making sure pins on back
of circuit board align with sockets in connector.
12. Turn ON power to unit.
NOTE: If a common wire has not been connected two AA
batteries must be used to power the thermostat.

Step 4 -- Thermostat Configuration -- Configu-
ration options are intended to be selected at inst_dlation and are
nonn_dly not modified by the home owner These options are
not discussed in the Homeowner's Guide and therefore must
be made as p_ut of the installation. A special procedure allows
entry into the Configuration mode. The themlostat will auto-
matically exit this mode if no button is pressed for 3 minutes.
While in the configuration mode, up to 14 option choices can
be made:
Option 01: Anticipator setting
Option 02: Clean filter setting
Option 03: Fahrenheit or Celsius selection
Option 04: Enable fan (G) on with W/Wl output
Option 05: HP/AC
Option 06: Cooling Ix_ckout (available only if an outdoor air
tempemtme sensor is present)
Option 07: Enable zoning
Option 08: Auxiliary heat lockout temperature adjustment
(available only on heat pump systems and if an outdoor air
temperature sensor is present)
Option 10: O (reveLsing valve) ON with Heat or Cool (present
on Heat Pump models only)
Option 13: Room temperature offset adjustment
Option 15: Enable AUTO mode
Option 18: Backlight configuration
Option 19: Number of wires
Option 21: Keypad Lockout
An explanation for each of these and how to enter the con-
figuration mode follows.

to a higher or lower value. The selected number is the number
of degrees, plus or minus, which will be added to the actu_fl
temperature. The number can range between -5 and +5. Facto-
ry default is 0. This adjusted v_flue will be used as actual tem-
perature for both display and control action. For example, if 2
is selected, 72 F actu_fl will read 74 E If set point is 72, the
room will control to an actual value of 70 which will be
displayed and acted upon as if it were 72. Tile effect is that a
positive number selection will make the room temperature
lower and vice versa. This thermostat is factory calibrated
within an accuracy of plus or minus 1° E so this adjustment
will provide the best accuracy when set to 0.
