Page 5: Important Safety Information
Important Safety Information • Always turn off power at the main power source by unscrewing fuse or switching circuit breaker to the off position before installing, removing, cleaning, or servicing this thermostat • Read all of the information in this manual before installing this thermostat • This thermostat should be installed only by a professional contractor • This is a 24 VAC low-voltage thermostat; do not install on voltages higher than 30 VAC • All wiring must conform to local and national building and electrical codes and ordinances • 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 • The thermostat will not control your heating/air conditioning system without power; it requires a continuous 24 VAC circuit for proper system control • Use this thermostat only as described in this manual • While cleaning, do not get soap directly on thermostat switches or LCD readout; only use a damp cloth with a mild soap to wipe outside of thermostat cover General Description ® The SimpleComfort 2201 is intended to operate and is compatible with 24 VAC residential heat pumps with up to 2-stage heat/2-stage cool. It will operate with multi-stage heat pump systems that are manual changeover and have auxiliary or emergency heating. There are no optional items required for standard installations. This thermostat is also compatible as a master thermostat in zoned system applications. ® The SimpleComfort 2201 will automatically control the heat and/or air conditioning system. When used properly, this thermostat can reduce heating and cooling costs throughout the year. -
Page 6: To Remove Existing 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. 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 below for old and new label identification. -
Page 7: To Install Thermostat
To Install 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. IMPORTANT: This thermostat is compatible with 100% lockout systems. To reset the system, turn thermostat to Off position for at least 60 seconds. 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. -
Page 8: Testing The Thermostat
12. Insert stripped, labeled wires in matching wire terminals. See Wiring Diagrams section of this manual (Pages 11- 24). CAUTION!: Be sure exposed portion of wires does not touch other wires. 13. 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. 14. Seal hole for wires with non-flammable putty or insulation. 15. Replace cover on thermostat by snapping it in place. 16. Turn on power to the system at the main service panel. 17. Test thermostat operation as described in the following section. Testing the Thermostat 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. 1. Put the Mode switch to Cool position. Mode 2. Press the button until the temperature setting is at least 3 degrees below the room temperature. The air conditioning system and fan should turn on within a few seconds. Cool Off Heat Emer 3. Put the Mode switch in the Off position. The air conditioning system should turn off. The fan may have a delay. Mode Note: Pressing the Reset button will bypass the 5-minute anti-short cycle compressor protection. - Page 9 Note: While in Cool or Heat mode, once the thermostat turns the system off, a built-in delay keeps the compressor from turning on for about 5 minutes. This protects the compressor. Mode 4. Put the Mode switch to the Heat position. 5. Press the button until the temperature setting is at least 3 degrees above room Cool Off Heat Emer temperature. The heating system should turn on. Note: The compressor may not turn on again for 5 minutes. Mode 6. Put the Mode switch to the Off position. The heating system should turn off. Once again the fan may have a delay. Cool Off Heat Emer 7. Put the Fan switch to the On position. The blower fan should turn on. Auto 8. Put the Fan switch to the Auto position. The blower fan should turn off. If all functions operate properly, the thermostat is installed correctly. Auto If the thermostat does not operate properly: • Check all wiring connections • See Troubleshooting (Page 25)

Page 10: Led Indicators
LED Indicators There are three LED indicators located on the front of the thermostat. They are designed to inform you of the following: AUX (GREEN): This turns on when the auxiliary (back-up) heating is in operation. This is the second (non-economy) stage of heat. It turns on 2 degrees below first stage and is not adjustable. CHECK (RED): When this turns on, a malfunction has occurred somewhere in the heat pump system. Please contact a qualified service technician as soon as possible to check your system. EMER (RED): This light turns on whenever the emergency heat is manually selected (system switch is in the EMER position). While in the emergency heat mode, the heat pump compressor is off, and the emergency heat (same as the auxiliary heat) maintains the setpoint temperature. EMER (RED) CHECK (RED) AUX (GREEN) Cool Off Heat Emer Auto Check Emer... -
Page 11: Operation
Operation 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. Note: Holding down either the or button will scroll the temperature display. The new temperature setting is automatically saved. After 5 seconds, the display returns to showing the current room temperature. Setting a New Temperature Differential IMPORTANT: The default temperature differential is factory set at 1°F. When your room temperature varies by 1°F, the thermostat turns your system on. If you notice your system turning on and off too frequently, increase the temperature differential accordingly. Step 1: Remove cover and press Reset button once. Step 2: The display will show This is the temperature differential setting. Step 3: Press the or button to adjust the temperature differential down or up. The display will return to the room temperature display five seconds Differential Setting °F °C after the last input. The new temperature differential setting will be 1°F 0.5°C saved. - Page 12 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, F or C using 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 switch into the Auto position. • In Auto, indoor fan runs only during a heating or cooling cycle • In ON, indoor fan runs continuously Auto Step 2: Move the Mode switch in either Cool or Heat position, depending on the season. Mode The thermostat will now operate and maintain the room temperature at the desired setpoint. Note: When the thermostat operates the system, there is built-in compressor Cool Off Heat Emer protection. After the compressor turns off, the system will not turn it back on for about five minutes. This protects the compressor.
