Emergency Heat
Push and release the MODE button until the display reads
E HT, and shows the
symbol. Your system is now in the
emergency heat mode. Emergency heat mode uses only the
auxiliary heat to maintain comfort. This should only be used
if for some reason your Spectra unit is inoperable. Note: If
your system is not equipped with auxiliary heat,
do not select the emergency heat mode.
Off
Push and release the MODE button until the display reads
OFF. When the word OFF is displayed the system will not
provide heating or cooling.
The display still shows room temperature and the fan is
operable. Avoid using the OFF mode during extremely cold
weather to prevent damage to your home from freezing.
How do I set the fan?
To select continuous fan operation, press and release the
FAN button and the display will show the animated fan
symbol. Continuous fan operation circulates the air in your
home.
Continuous fan operation is useful when using an air
cleaner for continuous air filtering or to help maintain even
air temperatures throughout a multilevel or large home.
(Using continuous fan does consume more energy.) The fan
will come on automatically whenever the system is operating,
but there will be no indication of this on the thermostat
display.
How does the setback feature of
my thermostat work?
Day/Night Button
Built in to your thermostat is an optional setback feature.
By pressing the Day/Night button, alternate set points may be
selected. When the primary (daytime) set points are selected,
the
symbol will be displayed. When the secondary
(nighttime) set points are selected, the
symbol will be
displayed.
