HOLD − Using Temperature Hold Modes

When HOLD is displayed at the HOME screen, the ther-
mostat is in a temperature hold condition. This means that
the temperature program data is ignored and the thermo-
stat functions much like a non−programmable thermostat.

Adjusting Temperature Setpoint in Hold Mode

The temperature setpoint represents the desired tempera-
ture of the space around the thermostat. The default heat
setpoint in hold mode is 70°F; the default cool setpoint in
hold mode is 78°F.

To adjust the setpoint, press the UP or DOWN (

YB

) arrow

buttons (see figure 8); the existing setpoint is displayed to
the right of the actual room temperature. Each button
press adjusts the setpoint up or down by 1 degree.

After the desired setpoint is reached, the HOME screen
will reappear after about 15 seconds.

Permanent Hold Mode

At any time the program is running, from the HOME
screen, set a permanent hold (program override) by press-
ing the HOLD button (see figure 8). The thermostat now
functions much like a non−programmable thermostat. Use
the Up/Down arrow buttons to adjust the hold setpoint. To
return to the program, press HOLD again.

Temporary (2-Hour) Hold

At any time the program is running, from the HOME
screen, set a temporary 2-hour hold by pressing the Up/
Down arrow buttons until the desired setpoint is displayed;
HOLD" flashes (see figure 9). This overrides the program
for 2 hours from the last button press, then returns to the
program.

While in Temporary Hold, press HOLD once to switch to
Permanent Hold (HOLD displays solid; PROG not dis-
played); press HOLD again to return to the program
(PROG displays; HOLD not displayed).

PROG − Thermostat Programming

The L3711C thermostat can be programmed to perform a
set of both heating and cooling events for each day of the
week. Each day can be programmed for 4 unique events
per day, and each day can be different from any other day.

To Set Program Events and Temperatures

Figure 10 gives an example of how up to 7 different pro-
grams can be set. Programs 

A

 and 

C

 reflect the desired

warmth while the home IS occupied (72°); 

B

 allows less

heating while the home is NOT occupied; 

D

 reflects a cool

sleeping temperature.

NOTE − The example in figure 10 shows heat setpoints; a
similar program may be set for cool setpoints.
