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: T hermostat 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. Insert stripped, labeled wires in matching wire terminals.
CAUTION!: Be sure exposed portion of wires does not touch other wires.
11. Gently tug wire to be sure of proper connection. Double check that each wire is connected to the proper
terminal.
12. Insert 2 "AAA" batteries into battery holder. Orient them in the proper direction.
13. Turn on power to the system at the main service panel.
14. Configure thermostat 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".

Remote or Outdoor Sensor Installation (Optional)
1. Remove cover from remote sensor housing.
2. Select an appropriate location for mounting the remote sensor.
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).

Installing and Changing Batteries
If your LCD is blank, or displaying LO BAT, the batteries are not installed or need to be changed. We suggest you
change the batteries at least once a year, or whenever the LO BAT warning displays.
Remove the cover, and install the two "AAA" alkaline batteries into the battery compartment. Proper battery
installation is important! Make sure the positive ends of the batteries match the positive terminals in the battery
compartment.
Batteries will provide power to maintain the clock during a power loss.
Configuration Mode
The configuration mode is used to set the SC5010 to match your heating/cooling system. The SC5010 functions
with heat pump, air conditioning, gas, oil or electric heat systems.
To configure the SC5010, perform the following steps:
1. Verify the SC5010 is in the OFF mode.
Press the SYS (left) button until off mode displays.
2. Remove the cover of the thermostat by gently pulling near one of the
corners at the top of the thermostat.
