Operating Modes
These are the possible operating modes of the
SC2311L
.
Off Mode
In off mode, the thermostat will not turn on the heating or cooling appliances.
Note 2:
The indoor fan can be activated in every mode by sliding the Auto/On fan to the On
position.
Note 2:
Off mode in used to enter the configuration setup (by pressing
LEFT
and
RIGHT
simultaneously for 5 seconds).
Cool Mode
In cool mode, the thermostat controls the cooling system.
There is a four minute time delay after the compressor turns off. This protects the compressor.
Heat Mode
In heat mode, the thermostat controls the heating system.
For heat pumps, there is a four minute time delay after the compressor turns off. This protects the
compressor.
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.
ENTER
Emergency heat mode by pressing the up button for ten seconds while in heat mode. “EH”
will then display on the screen.
EXIT
Emergency heat mode by pressing the up button for ten seconds. “EH” will not display on
the screen when you exit emergency heat mode.
The
SC2311L
also exits emergency heat mode when the mode switch is moved to Cool.
This feature is used for transferring the configuration settings 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:
1. The master must be powered by 24 VAC.
2. Verify the master thermostat is in
OFF
mode. Slide system switch to center
position.
3. Remove cover of the master thermostat by gently pulling near one of the corners
at the top of the thermostat.
4. Press the
up
and
down
buttons and
LEFT
switch simultaneously for 5 seconds.
5. The
OUT
screen displays indicating the master thermostat is ready to
transfer data.
Note:
Press the
up
and
down
buttons and
LEFT
switch simultaneously for 5
seconds to exit from data transfer mode and to return the master to the
OFF
mode.
6. 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:
Target thermostat must be powered by 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 6 down to 1. It will then display
LOC
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
LEFT
switch simultaneously for 5 seconds to exit
from the data transfer mode and to return the master thermostat to the
OFF
mode.

Starting the Thermostat
Room Temperature
CAUTION!
:
Do not use air conditioning when the outdoor temperature is below 50 degrees.
This can damage your air conditioning system and cause personal injuries.
1. Move the
Fan Auto/On
switch to the
Auto
position.
2. Move the
Cool/Off/Heat
switch to
Cool
or
Heat
, depending on the season.
Mode of Operation
The
SC2311L
is a two-stage heat, one-stage cool thermostat. It functions with air conditioning, heat
pumps, gas, oil or electric heat.
The thermostat activates the first stage heat when the room temperature is below the heat set
temperature (by the differential temperature). Second stage heat will be activated if the room
temperature continues to drop. The heat outputs are staged off as the room temperature increases.
For heat pump systems, the thermostat will not let the compressor come on for four minutes after it
turns off. This protects your compressor.
When the room temperature is greater than the cool set temperature (by the differential temperature),
the cooling device is activated. The cool output is turned off as the room temperature drops. The
thermostat will not let the compressor come on for four minutes after it turns off. This protects your
compressor.
The
SC2311L
has the following operating modes: OFF, Heat, Emergency Heat, and Cool. In OFF
mode, the thermostat will not turn on heating or cooling devices. In the Heat mode, the thermostat
controls the heating system. For heat pump systems, Emergency Heat mode is used to bypass
the compressor (only backup heat operates). In the Cool mode, the thermostat controls the cooling
system. The indoor fan can be turned on in all operating modes using the Fan switch.
Fan Test
1. Slide
