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 the appropriate circuit breaker off. 2. Remove cover of old thermostat. This should expose the wires. 3. Label the existing wires with the enclosed wire labels before removing wires. 4.
To Install Thermostat (continued) 2. To remove cover, insert and twist a coin or screwdriver in the slots on the sides of the thermostat. 3. 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). 4. Mark the placement of the mounting holes. 5. Set thermostat base and cover away from working area. 6. Using a 3/16” drill bit, drill holes in the places you have marked for mounting. 7.

Operation ® The SimpleComfort 3201 thermostat has buttons that are used to: • Adjust the setpoints of the thermostat • Set the modes • Program the schedule Setting the Room Temperature (Setpoint Temperature) 1. With the System switch in Cool, Heat, or Emer, the current temperature setpoint displays. 2. Press the or button until the desired temperature setpoint displays. 3. The new temperature setpoint is automatically saved in memory. Setting a New Temperature Differential 1.
LED Indictors There are three LED indicators located on the front of the thermostat.
Starting the Thermostat CAUTION!: Do not use air conditioning when the outdoor temperature is below 50 degrees. This can damage your air conditioning system and cause personal injuries. 1. Move the Fan Auto/On switch to the Auto position. On position runs indoor fan continuously. 2. Move the System switch to Cool or Heat, depending on the season.
Testing the Thermostat Once the thermostat is installed, it should be thoroughly tested. CAUTION!: Do not energize the air conditioning system when the outdoor temperature is below 50 degrees. It can result in equipment damage or personal injury. Note: Before testing the SC3201, move the Fan Auto/On switch to the Auto position. Cool Test 1. Slide System switch to Cool position. Cool mode screen is displayed. 2. Adjust set temperature so it is 5 degrees below room temperature. 3.
Emergency Heat Test 1. Slide System switch to Emer position. Emer Heat mode screen is displayed (Emer LED lights). 2. Adjust set temperature so it is 5 degrees above room temperature. 3. Second stage heat should come on within a few seconds (Aux LED lights). 4. Adjust the set temperature 2 degrees below the room temperature and the heat should turn off. There may be a fan delay on your system. Fan Test 1. Slide Fan switch to On position. 2. Indoor fan turns on. 3. Slide Fan switch to Auto position. 4.
Operating Modes Off Mode • In this mode, the thermostat will not turn on the heating or cooling devices (manual fan can operate) • OFF mode is also used to access Setup and Program modes Cool Mode • In this mode, the thermostat controls the cooling system • Press the Mode button to enter and exit Program Cool mode • In Program Cool (PROG displays) mode, the thermostat will follow the program schedule that is stored in memory Heat Mode • In this mode, the thermostat controls the heating system • Press
