INSTALLATION

What You Need

This thermostat includes two #8 slotted screws and two wall anchors

for mounting. To install your thermostat, you should have the follow-

ing tools and materials.

• Slotted Screwdriver(s)

• Small Philips screwdriver

• 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 existing 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 and thermostat. See Figure 1. Some

thermostats will have screws or other locking devices that must first

be removed. Once the 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.

Mount Wallplate and Thermostat

• Remove the wallplate from your thermostat by pressing the release

tab on the bottom of the thermostat. See Figure 2.

• Oil - Fired Furnace

• Single Stage Heat Pumps - with no

auxiliary heat

• Electric Furnace

• Electric Air Conditioning

This thermostat will NOT control multistage heat pumps or 110/220 V

baseboard electric heating systems.

2. Temperature Range

This thermostat can be set between 45°F and 95°F (7°C and 35°C).

However, it will display room temperatures from 30°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 displayed if the temperature is lower

than 30°F (0°C).

This thermostat will automatically cutoff in Heat mode if the tempera-

ture rises above 95°F (35°C), and automatically cutoff in Cool mode if

the temperature drops below 45°F (7°C).

3. Compressor Protection

This thermostat provides a 3.5 minute delay after shutting off the com-

pressor before it can be restarted. This feature will prevent damage to

your compressor caused by rapid cycling. It does not prevent a rapid

compressor restart due to short power outages.

4. Battery Warning

Two fresh AA alkaline batteries should provide well over one year of

service. However, when the batteries become drained, the Low Bat-

tery Indicator will flash on the display. When this message occurs,

install new alkaline batteries. You have approximately 1 minute to

change the batteries and keep the thermostat’s settings. Once the

batteries have become too low to ensure proper operation, your sys-

tem will be turned Off, and the display will be cleared except for flash-

ing Low Battery Indicator on the LCD display.

CAUTION: When only the battery icon flashes on the display,

the thermostat is shut down, and your system 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 thermo-

stat 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 bat-

teries prior to leaving.

Wire Labeling

• Each wire coming from the wall to the existing thermostat is con-

nected to a terminal point on that thermostat. Each of these termi-

nal points is usually marked with a code letter as shown in Table A

below.

• Note that this thermostat has multiple function terminals that allow

Single-Stage Heat Pump capability. Standard systems use: Rh, Rc,

G, Y, W. [Single-Stage Heat Pumps use: R, Y, G, and O or B.] Table A

below shows the multiple functions of the terminals. Use the termi-

nals 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 labeling procedures correctly, you do not have to be con-

cerned about how many wires there are.

• There is often no terminal 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 com-

plete the circuit.

• IMPORTANT! BEFORE DISCONNECTING ANY WIRES, APPLY THE SELF-

ADHESIVE LABELS PROVIDED TO THE WIRE AS SHOWN IN TABLE A

BELOW. (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 thermostat from the wall. This air could cause a false thermo-

stat reading.

NOTE: Do not connect a “Common” wire (sometimes labeled “C”) to

• Position wallplate on wall and pull existing wires through large open-

ing. Then level for appearance. Mark holes for plastic anchors pro-

vided, if your existing holes do not line up with those on the wallplate.

• Drill holes with 3/16” bit and gently tap anchors into the holes until

flush with wall.

• Reposition wallplate to wall, pulling wires through large opening.

Insert mounting screws provided into wall anchor and tighten. See

Figure 3.

Figure 3

NOTE: 5-wire Systems

If your thermostat has one wire marked R or Rh (2, 3, or 4-wire system),

then leave the jumper wire between the Rh and Rc terminals on the

wallplate. Otherwise, if you have separate Rh and Rc wires (5-wire

system), then remove the jumper wire between the Rh and Rc termi-

nals.

Connect Wires and Mount Thermostat to Wallplate

• Match and connect the labeled wires to the appropriate coded ter-

minal screws on the wallplate. (See Figure 4, 5.) Ignore any wires

which may be present, but which were not connected to the old

thermostat.

Figure 4 Figure 5

• Refer to the Wiring Diagrams below to be sure your system is wired

correctly.

• If your system is a single stage heat pump and uses an O or B wire,

you must move the System Selector switch inside the thermostat to

the Heat Pump position. If you have a normal furnace or electric

system, leave the switch in the Standard position. Refer to the Sys-

tem Selector section on the back for more information on this switch.

• Be sure to tighten the terminal screws securely, otherwise a loose

wire could cause operational problems with your system or thermo-

stat.

• Push excess wire back into the hole to prevent interference when

installing the thermostat to the wallplate.

• Make sure the System Switch is set to OFF, and the Fan Switch is set

to AUTO.

• Insert the tabs on top of the thermostat body into the slots at the

top of the wallplate. Press the bottom of the thermostat body into

the snap on the bottom of the wallplate. Refer to Figure 2. (NOTE:

Do not force the thermostat onto the wallplate, as the terminal pins

may be damaged. If it does not snap properly, the thermostat may

not work.)

• Insert the two AA size alkaline batteries, observing the polarity

marked inside the battery compartment.

• Switch on the main power at the panel or furnace.
