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.
Q. 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.
NOTE:
If the thermostat is set for 2 events a day instead of
4, the thermostat will only use the DAY and NITE events.
STATIC NOTICE
Thermostat is protected against normal static electric
discharges, however to minimize the risk of damaging
the thermostat in extremely dry weather, please touch a
grounded metal object before touching the thermostat.
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.
P. 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
(Figure 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.
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.
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
