compressor failure by “locking out”
the compressor. This ensures that the
compressor will stay off for approxi-
mately five minutes between cycles.
When the thermostat is in compressor
lock-out, the word COOL will flash.
During this period, the compressor will
not be energized
Programmable Fan Control.
This feature allows you to have your
fan operate continuously through one
or more programmed time periods.
This is useful if you want to have
constant air circulation during a
specific time period. If you do not use
this feature, the fan will cycle normally
with the heating and cooling system.
To program the fan, follow the steps in
the PROGRAMMING section. In each
time period, you can press the FAN
key to select a continuous fan or a
normally cycling fan. The display will
show
PRG FAN ON when continuous
fan is selected. This means at the time
you set the period to start, the fan will
come on and run continuously until the
next program time period
Example: Your thermostat is pro-
grammed with the original factory
settings for the Monday MOR period
in the heating mode.
Pressing PROGRAM
VIEW
will
display MOR, 6AM and 70 . Pressing
the FAN key will toggle the program-
mable fan ON and a second press
would turn it back OFF. When
PRG
FAN ON is in the upper right of the
display, your thermostat is pro-
grammed to adjust the temperature to
70
°
at 6AM and also bring the fan on
to run constantly until the next
program time period.
At the next time period you may
choose to continue the program fan
feature. Change to the next program
period and press the FAN key until
PRG FAN ON
is on the display. The
fan will continue to run through this
period as well as the previous one.
If the thermostat is in a period with
continuous fan and you want the fan to
cycle, press the FAN key.
PRG FAN
ON
on the display will turn off.
Air Filter Change-Out Indicator.
This feature allows the thermostat to
display
CHNG FLTR (change filter)
after a set time of fan operation. This is
a reminder to change or clean your air
filter. The factory set interval for
CHNG FLTR to be displayed is 200
hours of fan operation. This can be set
anywhere from 0 to 1950 hours in 25
hour increments. A selection of
00
will
cancel this feature.
When
CHNG FLTR
is displayed, you
can clear it by pressing the FILTER
key. This resets the timer and starts
counting the hours until the next filter
change.
