Important Safety Information
WARNING! : Always turn off power at the main power supply before installing, cleaning, or
removing thermostat.
• This thermostat is for 24 VAC applications only; do not use on voltages over 30 VAC
• Do not short across terminals of gas valve or system control to test operation; this will damage your
thermostat and void your warranty
• All wiring must conform to local and national electrical and building codes
• Do not use air conditioning when the outdoor temperature is below 50 degrees; this can damage your
A/C system and cause personal injuries
• Use this thermostat only as described in this manual
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. 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 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.
2. To remove cover, pull gently at the seam at the top.
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. Use a hammer to tap supplied anchors in mounting holes.
8. Align thermostat base with mounting holes and feed the control wires through slit in thermal
intrusion barrier and into wire opening.
9. Use supplied screws to mount thermostat base to wall.
10. For 2 transformer systems, remove and discard RC/RH jumper.
11. Insert stripped, labeled wires in matching wire terminals.
CAUTION!: Be sure exposed portion of wires does not touch other wires.
12. Gently tug wire to be sure of proper connection. Double check that each wire is connected to the
proper terminal.
13. Turn on power to the system at the main service panel.
14. Configure thermostat (see Page 12) to match the type of system you have.
15. Replace cover on thermostat by snapping it in place.
16. Test thermostat operation as described in “Testing the Thermostat” (Page 19).

3. Mount remote sensor unit using hardware provided.
4. Install two strand shielded wire between remote sensor and thermostat. Shielded wire must be used. Do not
run remote sensor wire in conduit with other wires.
• Wire 1 should run between the S1 terminal on the thermostat and the S1 terminal on the remote sensor
• Wire 2 should run between the S2 terminal on the thermostat and the S2 terminal on the remote sensor
• Connect the shielding of the wire to the S2 terminal on the thermostat
5. Configure the thermostat to operate with the remote sensor (see Configuration Mode setting 10, Page 14).
Note: Remote or outdoor sensor reading can be displayed by
simultaneously pressing the Down and SYS buttons.
Remote Sensor: (Shown: Optional ICM ACC-RT103 Remote Indoor Sensor;

Mode of Operation
The SC5011 is a programmable, manual or 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 (configurable) on the
thermostat will light. The SC5011 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 (configurable) on the thermostat will turn
on. The SC5011 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 SC5011 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 button. 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 (up or down button). This
puts the SC5011 thermostat into a 2-hour temporary hold. After 2 hours, it will automatically return to
the program schedule.
The programmable fan feature can be used to recirculate air while in Program mode. It is activated
during the program schedule set up.
The SC5011 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.

Operating Modes
There are five possible operating modes for the SC5011. Off, Cool, Heat, and Cool & Heat modes are
accessed by pressing the SYS (left) button. Program mode is accessed by pressing the SYS (left) and
FAN (right) buttons simultaneously.
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 pressing the FAN (right) button. The word FAN
shows on the display and the fan icon appears when the
fan operates.
Heat Mode
• In this mode, the thermostat controls the heating system. When the
heat outputs, the flame icon apprears on the display.
Note: For heat pumps, there is a four minute delay for your
compressor to restart after it has turned off.
Cool Mode
• In this mode, the thermostat controls the cooling system. When the
cooling outputs, the snowflake icon apprears on the display.
Note: There is a four minute delay for your compressor to restart
after it has turned off.

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.
• The timing display alternates with the set temperature every 10
seconds in the cool and heat mode.
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 (up or down button). After 2 hours, the program schedule
will automatically be resumed. To manually return to the program
schedule, press the PROG button twice.
