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 Extended Hold (Vacation) Mode and
HOLD and TEMP is showing in display. Press HOLD or RETURN
button to release permanent hold and return the thermostat to
normal program operation.
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.
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.
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).
Thermostat will not
allow me to program
a set point
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.
Check thermostat wiring to make sure that the fan control
wiring is connected to the correct terminals on the wiring
terminal block. See Installation and Wiring Diagrams sections of
this manual.
The room is too
warm or too cold.
See Review Set Temperature section of this manual to verify the
current set point and make any modifications that are necessary.
LO is shown in the
thermostat display
where the room
temperature is
normally displayed.
HI is shown in the
thermostat display
where the room
temperature is
normally displayed.
The temperature sensed by the thermostat is higher than the
90˚ F (32˚ C) upper limit of the thermostats display range.
The display will return to normal after the sensed temperature
lowers within the 45˚ to 90˚ F (7˚ to 32˚ 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 thermostat should the temperature exceed
99˚ F (37˚ C) in the heat mode.

The temperature sensed by the thermostat is lower than the
45˚ F (7˚ C) lower limit of the thermostats display range.
The display will return to normal after the sensed temperature
rises within the 45˚ to 90˚ F (7˚ to 32˚ 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.
