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.
Thermostat turns on
second (auxiliary)
stage of heating or
cooling too quickly or
not quickly enough.
Increase or decrease second (auxiliary) stage temperature
differential setting as appropriate to provide the desired
performance level. See Setting Temperature Differential and
Residual Cooling Fan Feature section of this manual.
Low Battery Indicator
is shown in
thermostat display.
Replace back-up batteries as soon as possible.
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.
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.
Thermostat display
is blank.
It is possible that AC power is not present at the thermostat and
the back-up batteries are fully discharged. Check fuse, circuit
breaker and thermostat wiring as appropriate to verify AC power
is available. Replace back-up batteries before re-programming
thermostat to make sure you have back-up power. See Low
Battery Detection and Replacement and Setting Your Energy
Saving Program sections of this manual.
Compressor protection features may be in effect due to
compressor short cycle conditions. See Compressor Protection
section for full explanation of this feature.
Heat Pump may be malfunctioning. Review the CHECK status
indicator light to see if it is lit. If the CHECK status indicator light
is lit, call a professional service technician to confirm heat pump
operation and provide necessary service. If heating is required
you can slide the system switch to EMER setting which will start
the Emergency Heat source to provide heating until the heat
pump can be serviced.
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.

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.
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 the display. Wait till next
setpoint and the temporary override will expire or change
setpoint temperature to desired comfort level.
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 first stage temperature differential setting
as appropriate to provide the desired performance level. See
Setting Temperature Differential and Residual Cooling Fan
Feature section of this manual.

POTENTIAL SOLUTION
If AC Power is present, call a professional service technician to
verify thermostat and system performance.
Thermostat will not
allow me to program
a setpoint
temperature higher
than 90˚ F (32˚ C).
This is above the normal thermostat temperature setting range
of 45˚ to 90˚ F (7˚ to 32˚ C).
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).

SYMPTOM
LO is shown in the
thermostat display
where the room
temperature is
normally displayed.
POTENTIAL SOLUTION
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.
Thermostat will not
allow me to program
a setpoint
temperature lower
than 45˚ F (7˚ C).
This is below the normal thermostat temperature setting range
of 45˚ to 90˚ F (7˚ to 32˚ C).
Fan continues to run
all the time whether
the system is on or
off.
Check that the fan control switch is in the AUTO position. This
will allow the fan to run only when the heating or cooling system
is turned on and running.

turned off.
The Residual Cooling Fan Control Feature can allow up to a 90
second fan delay after cooling system shutdown for energy
efficiency gains. The default setting is 60 seconds. This can be
changed to disable this feature or shorten the time period if
desired. See Setting Residual Cooling Fan Feature section of
this manual.
The room is too
warm or too cold.
See Review Set Temperature section of this manual to verify the
current setpoint and make any modifications that are necessary.
