Lux Products TX9600TS - Manual (Page 22)

LCD DISPLAY BACKLIGHT: The display screen is lighted to assist viewing at
nighttime, or in locations with low light levels. A press of any area on the
touch panel will light the display for approximately 10 seconds. Any screen
presses that occur while the light is on will reset the 10-second timer,
causing the screen to remain illuminated for an additional 10 seconds.
TEMPERATURE OVERRIDE: While in the Normal Run screen, the set
temperature can be temporarily changed by pressing the Set Temperature
digits, then pressing the UP or DOWN buttons. The set temperature will
return to the programmed value stored in memory when the start time of the
next upcoming program period is reached (Morn, Day, Eve, Nite). While a
Temporary Override is in effect, the words “HEAT OVRRIDE” or “COOL
OVRRIDE” will be shown in the display screen. An Override may be
cancelled by either pressing the HOLD button two times, or by moving the
mode switch to OFF, pausing briefly, then switching back to the HEAT or
COOL position. When in the Normal Run mode, the display should say either
“HEAT MODE” or “COOL MODE”.
MINIMUM RUN TIME: The thermostat has a default internal time delay of 5
minutes between load-on and load-off activations to prevent heating or
cooling system damage, which can occur from very frequent cycling. If
heating or cooling does not turn on right away with a manual change in set
temperature, please wait at least 5 minutes and the system should resume
normal operation.
TEMPERATURE HOLD: A Temperature Hold is used for maintaining a fixed set
temperature. Once a Hold is initiated, the thermostat will maintain the set
temperature indefinitely. A Hold may be used for days, weeks, or even
months at a time, as long as the thermostat has adequate power. To enter
Hold mode: press the HOLD button one time and the words “HEAT HOLD” or
“COOL HOLD” will appear in the display. To cancel a Hold, press the HOLD
button one more time. If a mains power failure occurs during a Temperature
Hold, the thermostat will continue to remain in Hold mode even after the
power comes back on.
NOTE: If you plan to leave the thermostat in Hold mode for an extended
duration (unattended), it is advisable to install new Energizer
® or
DURACELL ® "AA" size alkaline batteries prior to leaving to ensure reliable
operation of your heating and cooling system.
