Important Safety Information
WARNING!: Always turn off power at the main power supply before installing, cleaning, or removing the thermostat.
Package Contents/Tools Required
Package includes: SC5010 PRO thermostat on base, thermostat cover, wiring labels, screws, and wall anchors, 2 “AAA” batteries, Installation, Operation, and Application Guide Tools required for installation: Drill with 3/16” bit, hammer, screwdriver
Operating Modes
There are five possible operating modes for the SC5010. 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
Heat Mode
In this mode, the thermostat controls the heating system. When the heat outputs, the flame icon
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
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.
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.
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.
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 a heat pump, air conditioning, gas, oil, or electric heat systems. To configure the SC5010, perform the following steps:
Press the up or down button to change the settings within each screen. Press the right button to advance to the next screen.
Note: Pressing the left button will return you to the previous screen. To exit configuration mode, press the CONFIG switch for 1 second.
The setup screens for Configuration Mode are as follows:
Choose | System | Reversing Valve Active | Number of Com- pressors | Type of Heat |
Heat Pump | HP | O | 1 | |
HP | b | 1 | ||
Non-Heat Pump | Heat | Gas | ||
Heat | Electric |
The SC5010 is a programmable, manual or auto changeover, single-stage heat, and 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 SC5010 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 SC5010 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 SC5010 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 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 modes.
The programmable fan feature can be used to run the fan during occupied periods. The program schedule can be overridden by changing the set temperature (up or down button). This puts the SC5010 thermostat on a 2-hour temporary hold. After 2 hours, it will automatically return to the program schedule.The SC5010 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.
Wiring Diagrams
Once the thermostat is configured, 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.

Setting the Time and Day of the Week
The time and day of the week must be set for your program schedule to operate correctly.
Program Overview
The SC5010 programmable thermostat has four periods (MORN, DAY, EVE, NITE) that are customizable for each day of the week. Each period will have a start time, heat temperature, cool temperature, and programmable fan option. The SC5010 monitors the day and time while maintaining the specific conditions you have chosen for each period in your program.
Setting the program schedule:
From this screen you have 2 options:
From any of the previous screens, you can press the FAN (right) button to begin entering your program schedule. The days shown on the display will all be programmed simultaneously.
When the program schedule is complete, press and hold the PROG button (SYS and FAN buttons pressed simultaneously) for 2 seconds to return to the OFF mode.
Lockout Feature
The SC5010 has a button lockout feature so the mode cannot be changed and the temperature adjustment is limited. Select the appropriate lockout from Configuration Mode Settings (Step 5) of this guide. To activate the LOCK feature:
Factory Preprogramming
The SC5010 comes preprogrammed with the following schedule:

Personal Program Schedule
Use the following personal program schedule to record your settings
Requires SimpleSetTM Transfer Cable (ACC-WIH21)
This feature is used for transferring configuration and program schedule from the master to the target thermostat. All thermostats for a job can be mounted and powered up. Configure and program one thermostat. This will be the master. The master will be used to copy the program to the rest of the thermostats
Preparing the master to Send:
Note: The target thermostat must be powered with 24 VAC for field programming to occur When the connection has been made correctly, the master thermostat will power up and the target will count from 5 down to 1. It will then display the LOCK confirming the data has been saved in memory. When all target thermostats have been completed, reinstall the master thermostat.
Press the up and down buttons and the CONFIG switch simultaneously for 5 seconds to exit from the data transfer mode and to return the master thermostat to the OFF mode.
