1.

Press and hold TECHNICIAN SETUP

2.

button for 3 seconds. This 3 second delay
is designed so that homeowners do not

Tech Setup Steps

TECHNICIAN SETUP MENU

3.

Configure the installer options as
desired using the table below.

Use the or keys to change
settings and the NEXT STEP or
PREVIOUS STEP key to move from
one option to another. Note: Only
press DONE key when you want to
exit the Technician Setup options.

Filter

Change

Reminder

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.

You can adjust
the filter change
reminder from
OFF to 2000
hours of runtime
in 50 hour
increments.

Room

Temperature

Calibration

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.

You can adjust the
room temperature
display to ready -4°F
to +4°F above or
below the factory
calibrated reading.

Minimum

Compressor

On Time

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.

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.

Compressor

Short Cycle

Delay

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.

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.

Cooling

Swing

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 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.

Heating

Swing

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 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.

Keypad
Lockout

Keypad lockout
allows you to
configure the
thermostat so that
none or some of
the keys do not
function.

Pick PA or FU

PA = partial keypad
lockout, which locks
all the keys except the
or keys.

FU = Full keypad
lockout, which locks
out all the keys.

Note: Keypad lockout
