This feature will
flash “FILT” in the
display after the
elapsed run time
to remind the
user to change the
filter. A setting of
“off” will disable
this feature.
This feature allows
the installer to
change the
calibration of the
room temperature
display. For
example, if the
thermostat reads 70°
and you would like it
to read 72° then
select +2.
The compressor short
cycle delay protects
the compressor from
“short cycling”. This
feature will not allow
the compressor to be
turned on for 5
minutes after it was
last turned off.
The swing setting,
often called “cycle
rate”, “differential”
or “anticipation” is
adjustable. A smaller
swing setting will
cause more frequent
cycles and a larger
swing setting will
cause fewer cycles.
The swing setting,
often called “cycle
rate”, “differential”
or “anticipation” is
adjustable. A
smaller swing setting
will cause more
frequent cycles and a
larger swing setting
will cause fewer
cycles.
When on, this
feature turns off
the Y terminal 45
seconds after the
second stage of
heat turns on.
The heating swing
setting is adjustable
from ±0.4°F to
±2°F. For example:
A swing setting of
0.5°F will turn the
heating on at
approximately 0.5°F
below the setpoint
and turn the heating
off at approximately
0.5°F above the
setpoint.
Selectable on or off.
This option should be
“ON” for “DUAL
FUEL” applications
that use a gas
furnace for auxiliary
heat.
The cooling swing
setting is adjustable
from ±0.4°F to
±2°F. For example:
A swing setting of
0.5°F will turn the
cooling on at
approximately 0.5°F
above the setpoint
and turn the cooling
off at approximately
0.5°F below the
setpoint.
Selecting “ON” will
not allow the
compressor to be
turned on for 5
minutes after the last
time the compressor
was on. Select “off”
to remove this delay.
You can select the
minimum compressor
run time from “off”,
“3”, “4”, or “5”
minutes. If 3, 4, or 5
is selected, the
compressor will run
for at least the
selected time before
turning off.
You can adjust the
room temperature
display to ready -4°F
to +4°F above or
below the factory
calibrated reading.
You can adjust
the filter change
reminder from
“off” to 2000
hours of runtime
in 50 hour
increments.
Off 0 ºF Off On 0.8 ºF 0.8 ºF Off
This feature allows the
installer to select the
minimum run time for
the compressor.
For example, a setting
of 4 will force the
compressor to run for
at least 4 minutes
every time the
compressor turns on,
regardless of the room
temperature.
