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.
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 the heating and cooling system by removing the fuse or switching the appropriate
circuit breaker off.

Note: There is a four-minute time delay to protect the compressor after it
turns off.
Heat Test
1. Press mode button until heat mode is displayed.
2. Adjust the set temperature so it is 5 degrees above the room
temperature.
3. Heat should come on. Red LED turns ON.
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.
Note: For heat pumps, there is a four-minute delay to protect your compressor.

The SC3006 is a programmable, auto changeover, single stage heat, single stage cool thermostat. It
functions with air conditioning, heat pumps, gas, oil or electric heat systems.
The thermostat activates the heating appliance when the room temperature is below the set heat
temperature (by the differential temperature) and the red indicator light on the thermostat will light. The
SC3006 will stop outputting and the red light will turn off when the call for heat has been satisfied. With
heat pumps, the thermostat will not let the compressor come on for 4 minutes after it turns off. This
protects your compressor.
When the room temperature is greater than the set cool temperature (by the differential temperature),
the cooling device is activated and the green indicator light on the thermostat will turn on. The SC3006 will
stop outputting and the green light will turn off when the call for cooling is satisfied. The thermostat will
not let the compressor come on for 4 minutes after it turns off. This protects your compressor.
The SC3006 has five possible operating modes: OFF, Heat, Cool, Heat & Cool and Program mode. In off
mode, the thermostat will not turn on heating or cooling devices. The manual fan can be turned on in all
operating modes using the fan switch. In heat mode, the thermostat controls the heating system. In the
Cool mode, the thermostat controls the cooling system. In heat & cool mode, the thermostat controls
both the heating and cooling systems. In program mode, the thermostat will automatically be controlled by
the set program. Program mode can function with heat mode, cool mode or heat & cool mode. The clock
display alternates with the set temperature display for heat & cool mode.
The program schedule can be overridden by changing the set temperature ( or button). This puts the
SC3006 thermostat into a 2 hour temporary hold. After 2 hours, it will automatically return to the program
schedule.
The SC3006 also has a button lockout feature. This enables the thermostat to be set to the proper mode
and temperature and locked so it cannot be tampered with.
Mode of Operation

13
Operating Modes
There are five possible operating modes for the SC3006. Off, Cool, Heat, and Cool & Heat modes are
accessed by pressing the Mode button. Program mode is accessed by pressing the Prog button.
OFF Mode
• In this mode, the thermostat will not turn on the heating or cooling devices
Note: The indoor fan can be turned on manually in every operating mode by
sliding the auto/on switch to ON.
Cool Mode

Note: There is a four minute delay for your compressor to restart after it has
turned off.
Heat Mode
• In this mode, the thermostat controls the heating system
Note: For heat pumps, there is a four minute delay for your compressor to
restart after it has turned off.
Program Mode
• In this mode, the program function is on (PROG displays), and the thermostat
will automatically be controlled by the set program schedule. Program mode can
function with heat mode, cool mode or heat & cool mode. The program schedule
can be overridden by changing the set temperature ( or button). After 2
hours, the program schedule will automatically be resumed. To manually
return to the program schedule, press the button twice.
Cool and Heat Mode (Auto Changeover)
• In this mode, the thermostat controls the cooling and heating systems,
automatically changing over from one to the other as needed

Simpleset® Programming
Simpleset®programming is a convenient method of programming the thermostat. Once the entire Monday
(Day 1) schedule is set, Simpleset®programming will copy the Monday schedule to every day of the week.
After the complete Monday schedule is set (see Programming on Page 14), you are at the Day 2 screen:
1. Press the button once. Day 1 screen displays.
2. Press and hold the button for 3 seconds.
• The days of the week will count down from 7 to 1 and this will lock the
settings into memory.
• Once the schedule is locked in, you can go through each day and make
any changes you require. This feature speeds up the programming of
the standard weekday/weekend schedule.
3. Press and hold the button for 5 seconds to exit program mode and return to the OFF mode.
The SC3006 thermostat has a button lockout feature so the settings cannot be changed or tampered
with. With the lockout activated, any button press will result in “LOC” being displayed.
To activate the LOC function:
1. Press the button and hold it in.
2. Also press the button and keep both depressed for 10 seconds.
3. LOC will display and all buttons will be disabled.
To deactivate the LOC feature, repeat steps 1 & 2 above.
