CAUTION

!

To prevent electrical shock and/or equipment damage,

disconnect electric power to system at main fuse or

circuit breaker box until installation is complete.

This thermostat is intended for use with a low voltage system;

do not use this thermostat with a line voltage system. If in doubt

about whether your wiring is millivolt, line, or low voltage, have

it inspected by a qualified heating and air conditioning contrac-

tor or electrician.

Do not exceed the specification ratings.

All wiring must conform to local and national electrical codes

and ordinances.

This control is a precision instrument, and should be handled

carefully. Rough handling or distorting components could cause

the control to malfunction.

FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY

BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE

PERSONAL INJURY AND/OR PROPERTY DAMAGE.

DESCRIPTION

PRECAUTIONS

WARNING

!

Do not use on circuits exceeding specified voltage.

Higher voltage will damage control and could cause

shock or fire hazard.

Do not short out terminals on gas valve or primary

control to test. Short or incorrect wiring will damage

thermostat and could cause personal injury and/or

property damage.

Thermostat installation and all components of the

system shall conform to Class II (current limited)

circuits per the NEC code. Failure to do so could cause

a fire hazard.

INSTALLATION

REMOVE OLD THERMOSTAT

1. Shutoffelectricityatthemainfuseboxuntilinstallationis

complete.Ensurethatelectricalpowerisdisconnected.

2. Removethefrontcoveroftheoldthermostat.With wires

still attached, remove wall plate from the wall. If the old

thermostat has a wall mounting plate, remove the thermostat

and the wall mounting plate as an assembly.

3. Identify each wire attached to the old thermostat using

the labels enclosed with the new thermostat.

4. Disconnect the wires from old thermostat one at a time.

DO NOT LET WIRES FALL BACK INTO THE WALL.

5. Installnewthermostatusingthefollowingprocedures.

ATTENTION!

Thisproductdoesnotcontainmercury.However,thisproduct

may replace a unit which contains mercury.

Do not open mercury cells. If a cell becomes damaged, do

not touch any spilled mercury. Wearing nonabsorbent gloves,

takeup thespilledmercuryandplaceintoacontainerwhich

can be sealed. If a cell becomes damaged, the unit should be

discarded.

Mercurymustnotbediscardedinhouseholdtrash.Whentheunit

this product is replacing is to be discarded, place in a suitable

container. Refer to www.thermostat-recycle.org for location to

send product containing mercury.

ATTACH THERMOSTAT BASE TO WALL

1. Removethepackingmaterialfromthethermostat.Gentlypullthe

coverstraightoffthebase.Forcingorpryingonthethermostat

will cause damage to the unit.

2. Connectwiresbeneathterminalscrewsonbaseusingap-

propriatewiringschematic(seegs.2through4).

3. Placebaseoverholeinwallandmarkmountingholeloca-

tions on wall using base as a template.

4. Movebaseoutoftheway.Drillmountingholes.

5. Fastenbaselooselytowall,asshowning.1,usingtwo

mounting screws. Place a level against bottom of base,

adjustuntillevel,andthentightenscrews.(Levelingisfor

appearanceonlyandwillnotaffectthermostatoperation.)

If you are using existing mounting holes, or if holes drilled

are too large and do not allow you to tighten base snugly,

use plastic screw anchors to secure subbase.

6. Pushexcesswireintowallandplugholewithare-resistant

material(suchasberglassinsulation)topreventdraftsfrom

affecting thermostat operation.

ELECTRIC/GAS JUMPER (Fan Option)

Read the following information before clipping the nonelectric

heat jumper. If you are unsure of your application, contact a

qualified service person.

Ifyouremergencyorauxiliarysystemwillenergizetheblower,then

jumper,W904,onthethermostatbasemustbecut(seeg.1).

If your emergency or auxiliary heat system requires that the

thermostatenergizethefancircuit,donotcutjumperW904.

OPTIONAL BATTERIES

Withtwo"AA"batteriesinstalled,yourthermostatwillcontinu-

ouslydisplaythetemperatureduringalossofACpower.

CAUTION

!

To prevent compressor and/or property damage, if the

outdoor temperature is below 50°F, DO NOT operate

the cooling system.

CAUTION

!

Do not allow the compressor to run unless the

compressor oil heaters have been operational for 6

hours and the system has not been operational for at

least 5 minutes.

1. MoveSYSTEMswitchtoCOOL position.

2. Press to adjust thermostat setting below room tempera-

ture. The blower should come on immediately on high speed,

followed by cold air circulation
