L3011C THERMOSTAT
Cooling Demand
The thermostat must be in cool mode in order to properly
control the cooling equipment. When in cool mode, if the
room temperature is higher than the temperature setpoint,
a cooling demand is detected by the thermostat.
The thermostat will then activate the cooling equipment to
satisfy the demand. Cooling operation is indicated by a
snowflake icon in the SYSTEM box as shown in figure 7.
When the actual temperature drops below the temperature
setpoint, the snowflake icon will disappear. This indicates
that the cooling demand has been satisfied and that the
cooling equipment has been turned off.

NOTE − The cooling equipment is activated for at least 4
minutes if no buttons are pressed during the demand inter-
val. Cooling equipment operation is locked out for 5 min-
utes after a demand has been satisfied. If another cooling
demand occurs during this 5−minute interval, the snow-
flake icon will flash; however, the cooling equipment will
not run until the 5−minute delay has elapsed.
Adjusting Temperature Setpoint
The temperature setpoint represents the desired tempera-
ture of the space around the thermostat. The default tem-
perature setpoint is 70°F. To adjust the setpoint, press the
UP or DOWN arrow keys to the right of the display screen.
The existing setpoint will be displayed just below the actual
room temperature as shown in figure 8.

Figure 8. Setpoint Display and Adjustment
Use the UP or DOWN arrow keys to adjust the setpoint up
or down. The setpoint will increase by 1°F each time the
UP key is pressed. The setpoint will decrease by 1°F each
time the DOWN key is pressed.
After the desired setpoint is reached, the HOME screen
will reappear after about 8 seconds.
Fan Control
The FAN button is located behind the small door on the
right-hand side of the thermostat. See figure 3. The FAN
button can be used to select either continuous fan mode or
auto fan mode.
If continuous fan mode is enabled, the fan will run continu-
ously regardless of whether the heating or cooling equip-
ment is running. Also, ON will be displayed in the FAN box
as shown in figure 9.
