ITEM #08 (TEMPERATURE DIFFERENTIAL):
• The thermostat works by turning your heating system
on and off whenever the room temperature varies from
the desired set-point temperature.
•
Use the UP/DOWN buttons to change the number
value between 1 and 9. Generally your system
should cycle on about 3 to 6 times per hour. A smaller
differential number makes the system cycle more
frequently, so the room temperature is more precise
and constant. A larger differential number will make the
system remain on for a longer duration each time and
decreases the number of cycles per hour.
• Default is set to 4.

Q. Thermostat Operation Instructions
SET DAY AND TIME:
Place the SET switch into the DAY/TIME position. With
the day flashing press UP or DOWN to set the day or the
week. Press NEXT and the clock time will start flashing.
Use UP or DOWN to set the time; verify the AM/PM
indicator is correct. Return the SET switch to RUN position
when finished.
HEATING:
Basic operation of the thermostat can be obtained with
the SET switch in the RUN position. The temperature
can be adjusted using the UP and DOWN buttons.
When the thermostat is first powered on, it will follow
a default temperature routine that is preset from the
factory
(Table 14.1)
.
LCD DISPLAY BACK LIGHT:
The display screen is lighted to assist viewing at nighttime,
or in locations with low light levels. Press any button on
the front panel to activate the approximate 10 second back
light.
TEMPERATURE OVERRIDE:
While thermostat is in RUN mode, the set temperature
can be temporarily changed by pressing UP or DOWN.
The temporarily changed set temperature will return to the
programmed value stored in memory when start time of
the next upcoming scheduled event is reached (MORN,
DAY, EVE, OR NITE). While the temporary changed set
temperature is in effect, the word OVERRIDE will be shown
on the display screen. To cancel, move TEMPERATURE
switch to OFF and back to HEAT again.
TEMPERATURE HOLD:
Temperature hold is used for maintaining a fixed set
temperature; once a HOLD is initiated, the thermostat will
maintain the set temperature indefinitely. To enter a HOLD
state, press the HOLD button one time and the word HOLD
will appear on the display. To cancel, press the HOLD
button once again.
R. Thermostat Temperature Programs
The thermostat by default has 4 separate program events
they are: MORN, DAY, EVE, and NITE. Each event ends at
the start time of the following event.
NOTE:
When the last event is finished for each day
or group of days, the thermostat will advance
forward into the next day or group of days.
6. Use steps 3 through 5 to set up the events for the rest
of the week or group of days.
7. Return the SET switch back to RUN.
NOTE:
If the thermostat is set for 2 events a day instead
of 4, the thermostat will only use the DAY and
NITE events.
SET TEMPERATURE PROGRAMS:
1. Move TEMPERATURE switch to HEAT.
2.
Move SET switch to TEMP PROG position.
3.
Starting with Monday, use the UP or DOWN buttons to
adjust the start time and set temperature for the MORN
event, and then press NEXT button to advance.
4. Adjust the start time and set temperature of the DAY
event then press NEXT button.
5. Continue in this same manner to adjust the start time
and set temperatures for the EVE and NITE events for
Monday.
STATIC NOTICE
Thermostat is protected against normal static electric
discharges, however to minimize the risk of damaging
