Read This Before Installing Thermostat

IMPORTANT

1Read the entire installation section of this

Owner’s Manual thoroughly before you begin

to install or operate your Climate Technology Ther-

mostat.

INSTALLATION

2All installation is normally performed at your

thermostat.

ARMCHAIR PROGRAMMING

3You can program your thermostat before

installation by inserting the batteries and following

the instructions starting on page 16. This can be done

while you relax in your favorite chair and is a very

good way to familiarize yourself with all the functions

of your Climate Technology Thermostat.

OPERATION

4Your Thermostat is designed to operate with

most gas, oil, electric or 2-wire hot water heating

and air conditioning systems. It will also operate

single-stage heat pumps that do not have auxiliary

or emergency heat. These have 24-volt or millivolt

control systems and represent most central heating,

air conditioning, or space heating units in use in the

United States.

This Climate Technology Thermostat will NOT

control multi-stage heat pumps or 110/220

Volt systems.

COMPRESSOR PROTECTION

5The thermostat provides a 3.5 minute delay after

shutting off the heating or cooling system before

it can be restarted. This feature will prevent damage

to your compressor caused by rapid cycling. Note

that this delay also applies to the heating system

control. It does not prevent a rapid compressor re-

start due to short power outages.

TEMPERATURE RANGE

6Your thermostat can be programmed between

45°F and 95°F (4°C and 35°C). However, it will

display room temperatures from 32°F to 99°F (0°C

and 37°C). “HI” will be displayed if the temperature

is higher than 99°F (37°C), and “LO” will be dis-

played if the temperature is lower than 32°F (0°C).

This thermostat will automatically cut off in Heat

mode if the temperature rises above 95°F (35°C),

and automatically cut off in cool mode if the tem-

perature drops below 45°F (7°C).

Read This Before Installing Thermostat (continued)

POWER FAILURE

7Whenever the main power is interrupted or fails,

the battery power retains the programs and cur-

rent time.

AUTO RECOVERY

8Your thermostat is set from the factory to gradually

recover the room temperature from an energy sav-

ing program to your comfort program. Therefore, the

thermostat may turn your system on several minutes

prior to your programmed time. This operation is nor-

mal, but can be turned off. Refer to the Selector

Switches information on page 24.

BATTERY WARNING

9Fresh alkaline batteries should provide over one

year of service. However, when the batteries be-

come drained, the Low Battery indicator will flash on

the display. When this message occurs, install 2 new

AA batteries. You have approximately 1 minute to

change the batteries and keep thermostat’s clock and

program settings. Once the batteries have become too

low to ensure proper operation, your system will be

turned Off, and the display will be cleared except for

the Low Battery indicator flashing on the LCD display.

CAUTION:

Once the Low Battery only display oc-

curs, the thermostat is shut down, and your sys-

tem will no longer operate. In this condition,

there is no temperature control of your dwelling.

NOTE:

The INDIGLO®night-light will not function

when the thermostat is in low battery condition.

NOTE:

If you plan to be away from the premises

over 30 days, we recommend that you replace

the old batteries with new alkaline batteries

prior to leaving.

INSTALLATION

What You Need

This thermostat includes two #8 screws and two wall

anchors for mounting. To install your thermostat, you

should have the following tools and materials.

■Phillips and Slotted Screwdrivers

■Hammer

■Electric drill and 3/16" bit

■Two 1.5 V (AA) size alkaline batteries (included)

Remove Old Thermostat

CAUTION:

Do not remove any wiring from exist-

ing thermostat before reading the instructions

carefully. WIRES MUST BE LABELED PRIOR TO

REMOVAL.

■IMPORTANT! Turn off the power to the furnace at

the main power panel or at the furnace.

■Remove existing thermostat cover. See Figure 1.

Some thermostats will have screws or other lock-

ing devices that must first be removed. Once wall

mounting plate is exposed, look for wires.

If wires are not visible, they may be connected to the

back of the wallplate. Again, look for screws, tabs,

etc. Some models have doors that open to expose

wires and mounting screws. (See Figure 1).

TYPICAL HOME THERMOSTATS

Figure 1

Wall Mounting Plate Thermostat Cover

Wire Labeling

■

Each wire coming from the wall to the existing

thermostat is connected to a terminal point on

that thermostat. Each of these terminal points is

usually marked with a code letter as shown in

Table A on the next page.

■Note that this thermostat has multiple function

terminals that allow Single-Stage Heat Pump ca-

pability. Standard systems use: Rh, Rc, G, W.

[Single-Stage Heat Pumps use: Rh, Y1, G, and O or

B.] Table A below shows the multiple functions of

the terminals. Use the terminals that match your

system.

■The number of wires in your system can be as few

as two (for heat only systems), as many as eight,

or any number in between. If you follow the label-

ing procedures correctly, you do not have to be

concerned about how many wires there are.

■There is often no ter-

minal marking on the

existing thermostat of

two wire, heat only

systems. Just connect

either of the wires to

the RH terminal, then

connect the other wire

to the W terminal to

complete the circuit.

■IMPORTANT! BEFORE DISCONNECTING ANY

WIRES, APPLY THE SELF-ADHESIVE LABELS PRO-

VIDED TO THE WIRE AS SHOWN IN TABLE A ON

THE NEXT PAGE. (For example, attach the label

marked W to the wire that goes to the W or H

terminal on your existing thermostat.) IGNORE

THE COLOR OF THE WIRES since these do not

always comply with the standard.

■After labeling wires, disconnect them from the

existing thermostat terminals.

■Remove existing wallplate. To make sure wires do

not fall back into wall opening, you may want to

tape them to the wall.

■If hole in wall is larger than necessary for wires,

seal this hole with insulating material so that no

hot or cold air can enter the back of the thermo-

stat from the wall. This air could cause a false

thermostat reading.

NOTE:

Do not connect a “Common” wire (sometimes labeled “C”) to any terminal on this thermostat.

Tape up the wire and do not use. This wire provides electricity to non-battery powered thermostats.
