Verify your program setpoint time entries. The heating and
cooling programs utilize the same setpoint times, but have
individual setpoint temperatures for the MORN , DAY , EVE and
NIGHT
setpoints. See Setting Your Energy Saving Program
section of this manual.
Thermostat Program has been temporarily overridden and
program indicator is flashing in display. Wait until next setpoint
and the temporary override will expire or change the setpoint
manually for comfort.
Thermostat program is in Permanent Hold (Vacation) Mode and
HOLD and TEMP is showing in display. Press HOLD button to
release permanent hold and return the thermostat to normal
program operation.
Thermostat turns
heating or cooling
system on too often
or not often enough. Increase or decrease temperature differential setting as
appropriate to provide the desired performance level. See
Setting Temperature Differential and Residual Cooling Fan
Feature section of this manual.
Thermostat does not
turn on heating or
cooling system.
Check to see if OFF is shown in display. This indicates that the
system is turned off at the thermostat. Move the system
selector switch to the HEAT or COOL position. After the
compressor short cycle protection 5-minute period expires the
system should start within a minutes time.
Compressor protection features may be in effect due to
compressor short cycle conditions, power outages or rolling
blackouts. See Compressor Protection Feature section for full
explanation of this feature.
Heating or cooling system may be malfunctioning. Call a
professional service technician to verify system operation.
Thermostat turns on
heating instead of
cooling. Check thermostat wiring to make sure that the heating and
cooling stages are connected to the correct terminals on the
wiring terminal block. See Installation and Wiring Diagrams
sections of this manual.

Thermostat will not
follow program
setpoints. Check current time of day, day of week program settings. Make
sure to verify AM/PM indicator is accurately displaying desired
time settings. See Setting Current Time of Day and Day of Week
section of this manual.
Check to see if
OFF is shown in display. This indicates that the
system is turned off at the thermostat. Move the system
selector switch to the HEAT or COOL position. After the
compressor short cycle protection 5-minute period expires the
system should start within several seconds.
Low battery indicator
is shown in
thermostat display. Replace batteries immediately to maintain proper system
operation. See Low Battery Detection and Replacement
section of this manual.
OFF is shown in
thermostat display
and heating or
cooling system will
not start.
This indicates that the system is turned off at the thermostat.
The thermostat must be in
HEAT
or
COOL
modes of operation to
control the heating or cooling system. Move the system selector
switch to the
HEAT
or
COOL
position.
Thermostat display
is blank.
It is possible that the batteries are drained and not providing
power for the thermostat to control the system. Replace
batteries immediately to maintain proper system operation. See
Low Battery Detection and Replacement section of this manual.
If you replace the batteries and the display does not appear, call
a professional service technician to verify thermostat and
system performance.

SYMPTOM POTENTIAL SOLUTION
LO is shown in the
thermostat display
where the room
temperature is
normally displayed.
The temperature sensed by the thermostat is lower than the 40˚
F (5˚ C) lower limit of the thermostats display range. The display
will return to normal after the sensed temperature rises within
the 40˚ to 99˚ F (5˚ to 37˚ C) display range. If the temperature in
the controlled space seems to be normal, wait for the
thermostat to acclimate to the correct room temperature. If the
room seems to be colder than usual, turn on the heating system
to raise the temperature as needed for comfort within the room.
This condition could occur from the system being turned off
during a cold weather period or upon installation when the
thermostat has been stored for a long period of time in a cold
vehicle or location prior to being installed. The thermostat
should be allowed to warm up prior to installation to allow
proper heating control once installed.
HI is shown in the
thermostat display
where the room
temperature is
normally displayed.
The temperature sensed by the thermostat is higher than the
99˚ F (37˚ C) upper limit of the thermostats display range. The
display will return to normal after the sensed temperature
lowers within the 40˚ to 99˚ F (5˚ to 37˚ C) display range. Turn on
the cooling system or use other methods to lower the
temperature accordingly.
This condition could occur from the system being turned off
during an exceptionally warm period or upon installation when
the thermostat has been stored for a long period of time in a
warm vehicle or location prior to being installed. The thermostat
is equipped with a mechanical high temperature safety switch
that will turn off the system should the temperature exceed 99˚
F (37˚ C).
