Important Safety Information

• Always turn off the thermostat before installing, removing, cleaning, or servicing; turn off the power at

the main power source by unscrewing fuse or switching off circuit breaker

• Do not switch to “Cool” if outside temperature is below 50°F (10°C), this could damage your A/C system

and cause injury

• Do not install on voltages higher than 30 VAC

• All wiring must conform to local and national building and electrical codes and ordinances

• While cleaning, do not get soap directly on thermostat switches or LCD readout; only use a damp cloth

with a mild soap to wipe the outside of the thermostat cover

Package Contents/Tools Required

Package includes: SimpleComfort®2001 non-programmable thermostat on base, thermostat cover, wiring

labels, screws and wall anchors, Installation, Operation and Application Guide.

Tools required for installation: Drill with 3/16” bit, hammer, screwdriver.

General Description

• The SimpleComfort®2001 thermostat is a hardwired, digital, mercury-free, non-programmable,

electronic thermostat

• Compatible with single stage heating systems, heating/cooling systems, and heat pump systems, works

with gas, oil, or electric systems

• Suitable as a master thermostat in zoned system applications

• Separate setpoints for heating and cooling

• Freeze Protection Feature: Protects pipes from freezing! If the room temperature drops to 40°F, the

thermostat automatically turns on the heat; the thermostat must be in the Heat position

• Built-in Compressor Protection for Air Conditioners; to protect the A/C’s compressor, there is a 5-minute

delay between the system turning off and the A/C starting

• 30-minute power loss memory retention protection

ELECTRICAL SHOCK HAZARD – Turn off power at the main service panel by removing the fuse

or switching the appropriate circuit breaker to the OFF position before removing the existing

thermostat.

1. Turn off power to the heating and cooling system by removing the fuse or switching off the appropriate

circuit breaker.

2. Remove cover of old thermostat. This should expose the wires.

3. Label the existing wires with the enclosed wire labels before removing wires. See table on Page 6 for

old and new label identiﬁcation.

4. After labeling wires, remove wires from wire terminals.

5. Remove existing thermostat base from wall.

6. Refer to the following section for instructions on how to install this thermostat.

To Remove Existing Thermostat

ELECTRICAL SHOCK HAZARD – Turn off power at the main service panel by removing the fuse

or switching the appropriate circuit breaker to the OFF position before removing the existing

thermostat.

IMPORTANT: Thermostat installation must conform to local and national building and electrical

codes and ordinances.

Note:

Mount the thermostat about ﬁve feet above the ﬂoor. Do not mount the thermostat on an

outside wall, in direct sunlight, behind a door, or in an area affected by a vent or duct.

1. Turn off power to your system. Move the Mode switch to Off

2. Move the Fan switch to Auto.

3. To remove cover, insert and twist a coin or screwdriver in the slots on the sides of the thermostat.

To Install Thermostat

To Install Thermostat (continued)

4. Put thermostat base against the wall where you plan to mount it (Be sure wires will feed through the

wire opening in the base of the thermostat).

5. Mark the placement of the mounting holes.

6. Set thermostat base and cover away from working area.

7. Using a 3/16” drill bit, drill holes in the places you have marked for mounting.

8. Use a hammer to tap supplied anchors into mounting holes.

9. Align thermostat base with mounting holes and feed the control wires through wire opening.

10. Use supplied screws to mount thermostat base to wall.

CAUTION!

Be sure exposed portion of wires does not touch other wires.

11. Tighten screws on terminal block. Gently tug wire to be sure of proper connection. Double check that

each wire is connected to the proper terminal.

12. Seal hole for wires behind thermostat with non-ﬂammable insulation or putty.

13. Set the Gas/Electric switch to electric or gas/oil, and heat pump jumper to NON-HP or HP.

14. Set the temperature scale jumper to Fahrenheit or Celsius.

15. Replace cover on thermostat by snapping it in place.

16. Turn on power to the system at the main service panel.

Replace the old labels with the enclosed new labels:

it is the common side of the transformer, connect to C terminal

Setting the Room Temperature (Setpoint Temperature)

Step 1: Press the or button; the current temperature setpoint displays.

Step 2: Press the or button until the desired temperature setpoint displays.

The new temperature setting is automatically saved. After 5 seconds, the display returns to showing the

current room temperature.

Setting a New Temperature Differential

The default temperature differential is 1°. When your room temperature varies by 1°F, the thermostat

turns on your system. If you notice your system turning on and off too frequently, increase the

temperature differential.

Step 1: Remove the cover and press the Reset button once.

Step 2: For the ﬁrst 10 seconds of operation, the temperature differential is displayed.

Press the or button to select desired setting.

Changing Fahrenheit to Celsius

The temperature displays in degrees Fahrenheit as a factory set default. Follow these steps to change to

degrees Celsius:

Step 1: Remove the cover.

Step 2: Move the F/C jumper to the desired position, For Cusing the center pin as a common.

Step 3: Press the Reset button once and reinstall the cover.

Your LCD readout changes accordingly.

Starting the Thermostat

Step 1: Move the Fan Auto/On switch into the Auto position.

Step 2: Move the Mode switch to Heat or Cool,depending on the season.

Operation

CAUTION!

Do not switch system to cool if the outdoor temperature is below 50°F (10°C). This can

damage the air conditioning system and may cause personal injury.

Action: Set the Mode switch to Cool. Press the button until the temperature setting is 3°F below the

room temperature.

Result: The A/C system and fan should turn on.

Action: Set the Mode switch to Off.

Result: The A/C should turn off (there may be a fan delay).

Action: Set the Mode switch to Heat. Press the button until the temperature setting is 3°F above the

room temperature.

Result: The heating systems and fan should turn on (there may be a time delay depending on your

system).

Action: Set the Mode switch to Off.

Result: The heating system should turn off (there may be a fan delay).

Action: Set the Fan switch to On (continuous indoor fan operation).

Result: The blower fan should turn on.

Action: Set the Fan switch to Auto.

Result: The blower fan should turn off.

If the above test was successful, you have a proper installation.

If not:

Double check that wires are securely connected and are connected to the proper terminals. Consult

the troubleshooting section (see Page 12).
