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.
Heat Test
1. Press SYS (left) 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 within a few seconds. Red LED may turn 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 after it turns off. To bypass the
compressor time delay, go to OFF mode for 5 seconds.

Mode of Operation
The SC5811 is a programmable, manual or auto changeover, 2-stage heat, 2-stage cool thermostat. It functions
with air conditioning, heat pumps, gas, oil or electric heat systems. An outdoor sensor can be used to monitor the
outdoor temperature.
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 (congurable) on the thermostat will light. The SC5811
will stop outputting and the red light will turn off when the call for heat has been satised. 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 (congurable) on the thermostat will turn on. The SC5811 will
stop outputting and the green light will turn off when the call for cooling is satised. The thermostat will not let the
compressor come on for 4 minutes after it turns off. This protects your compressor.
The SC5811 has ve 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
SC5811 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 SC5811 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 ve possible operating modes for the SC5811. 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

Emergency Heat Mode (Heat pump systems only)
• In emergency heat mode, the heat pump system will be disabled and auxiliary
heat will become the primary source of heat.

Troubleshooting
SimpleSetTM Field Programming
This feature is used for transferring conguration and program schedule from the master to the target thermostat.
All thermostats for a job can be mounted and powered up. Congure 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:
1. The master must be powered with 24 VAC.
2. Verify the master thermostat is in OFF mode.
3. Press SYS (left) button until OFF mode displays.
4. Remove cover of the master thermostat by gently pulling near one of the corners at the top
of the thermostat.
5. Press the up and down buttons and CONFIG switch simultaneously for 5 seconds.
6. The OUT screen displays indicating the master thermostat is ready to transfer data.
Note: PresstheupanddownbuttonsandCONFIGswitchsimultaneouslyfor5seconds
toexitfromdatatransfermodeandtoreturnthemastertotheOFFmode.
7. Turn off power to the master and remove it from the wall.
8. Connect the master to the target using the 3 wire connector. Attach one end to the Master’s
FP pins and the other end to the Target’s FP pins.
Note: Targetthermostatmustbepoweredwith24VACforeld

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 conrming 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.
