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.
Be sure exposed portion of wires does not touch other wires.
Before wiring, remove pre-installed RC/RH jumper.
The configuration mode is used to set the SC4011 Pro to match your heating/cooling system. The SC4011 Pro functions with heat pump, air conditioning, gas, oil or electric heat systems.
To configure the SC4011 Pro, perform the following steps:
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 Compressors or Compressor Stages | Type of Heat |
Heat Pump | HP | O | 1 | |
HP | b | 1 | ||
Non-Heat Pump | Heat | Gas | ||
Heat | Electric |
Press the up or down button to select.
Press the right button to advance to the next screen.
The SC4011 Pro is an 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 SC4011 Pro 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 SC4011 Pro 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 SC4011 Pro has four possible operating modes: OFF, Heat, Cool, and Heat & Cool 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. The clock display alternates with the set temperature display for heat & cool mode.
The SC4011 Pro 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.
There are four possible operating modes for the SC4011 Pro. 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.
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.
Note: For heat pumps, there is a four minute delay for your compressor to restart after it has turned off.
Note: There is a four minute delay for your compressor to restart after it has turned off.
Once the thermostat is configured, it should be thoroughly tested.
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:For heat pumps, there is a four-minute delay to protect your compressor after it turns off. To bypass the compressor time delay, go to OFF mode for 5 seconds.

The SC4011 Pro 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:
To deactivate the LOCK feature, repeat steps 1 and 2 above.
Requires SimpleSetTM Transfer Cable (ACC-WIH21)
This feature is used for transferring the configuration from the master to the target thermostat. All thermostats for a job can be mounted and powered up. Configure one thermostat. This will be the master. The master will be used to copy the configuration to the rest of the thermostats.
Preparing the master to Send:
Note: Press the up and down buttons and CONFIG switch simultaneously for 5 seconds to exit from data transfer mode and to return the master to the OFF mode.
Note: 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.
