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 Diagram
sections of this manual.
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 until 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 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.
Thermostat turns on
second (auxiliary) stage
of heating or cooling
too quickly or not
quickly 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.
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.
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.
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.
Thermostat will not
allow me to program a
setpoint temperature
higher than 90˚ F (32˚C).
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 reprogramming
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.
If AC Power is present, call a professional service technician to
verify thermostat and system performance.
This is above the normal thermostat temperature setting range
of 45˚ to 90˚ F (7˚ to 32˚ C).
Thermostat will not
allow me to change
the setpoint.
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
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 thermostat should the temperature exceed
99˚ F (37˚ C).
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.
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).

Thermostat turns on
heating instead of
cooling, or cooling
instead of heating.
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.
