2. If an existing thermo statis bein g replaced:

a. Remove ex isting thermostat from wall.

b. Disconnect wiresfrom existing thermostat,one at a

time. Be careful not to allow wires to fall back into wall.

c. As each wire is di sconnected, record wire color and

terminal marking.

d. Discard or recycle old thermo stat.

ENVIRONMENTALHAZARD

Failure to follow this caution may result in environmen tal

damage.

Mercury is a hazardous waste. Federalregulations require that

Mercurybe disposed of properly.

CAUTION

!

3. Separate frontand back (mounting base) assembly of ther-

mostat.

4. Route thermostat wires through hole in mounting base.

Level mounting base against w all (for aesthetic value only,

thermostatneed not be level for properoperation) and mark

wallthrough 2 mounting holes.

5. Drill two 3/16 --in. mounting holes in wall where marked.

6. Secure mountingbase to wall with 2 anchors andscrews

provided making sure all wires extend through hole in

plastic.

7. Strip 1/4 in. insulation from thermostat wire and adjust

length to reach terminal block connector on mounting base.

Match and connect proper wiring in accordan cew ithwi ring

diagrams.

8. Push any excess wire back into wall. Seal h ole in wall to

prevent air leaks. Leaks can affect th ermostat operation.

Any excess wire left inside thermostat casing may also af-

fect thermostat operation by interferin g with airflow across

thetemperature sensor.

9. Snap thermostattogether making sure terminalblock con-

nectoraligns, and assemblyis secure.

10. Turn on power to unit.

On power up, dependingon the thermostat model beingused, the

LCD readout will display either, AC or PC for air conditioner

model (1--stage heat/1--stagecool), or HP or PH for heat pump

model(2--stageheat/1--stagecool).

Step 3 — Set Thermostat Configu ration

Configuration options allow the installer to configure the

thermostat for a particular installation. T hese selections are

intended tobe made at installation and normallyare not modified

by the homeowner.Below is a list of availableoptions followedby

a description of each one.

Option01 -- Equipment Type

Option 03 -- Fahrenheit or Centigrade operation

Option 04 -- Enable fan (G) ON with heat (W)

Option10 -- O (reversing valve)On with Heat or Cool (present

on HeatPump model only)

Option13 -- Room temperatureoffset adjustment

Note that not all configuration option numbers are used in this

product.

ToEnter The Configuration Mode:

Press and holdFAN button for approximately10 sec until room

temperaturedisappears and thedisplay reads “01”. Youare now in

configurationmode.

Conditioners)which are used in motel rooms and other

rented spaces. When this option is selected, the display

shows only the setpoint,not the room temperature. Also

the compressor timeguard is disabled, allowing the

compressortoturnonimmediatelywhenademandis

established.

HP or PH controls1 speed heat pump with1 stage of aux heat.

AC or PC controls1 speed air conditioner withone stage of heat.

Note that thisoption allows a HP thermostat to be convertedto

controlan AC system.

Option 03 — Fahrenheit/Centigrade Selection

This selection operates the thermostat in either Fahren heit or
