SYMPTOM POTENTIAL SOLUTION
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, section 4 of this manual.
SYMPTOM POTENTIAL SOLUTION
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
ON position.
Compressor protection features may be in effect due to
compressor short cycle conditions. See Compressor Protection
Feature section for full explanation of this feature.
Heating or cooling system may be malfunctioning. Call a
professional service technician immediately to verify system
operation.
Low battery indicator is
shown in thermostat
display. Replace batteries immediately to maintain proper system
operation. See Battery Replacement, section 7 of this manual.
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 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.
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 5 of this manual to verify
the current setpoint and make any modifications that are
necessary.
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.
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).
LO is shown in the
thermostat display
where the room
temperature is
normally displayed. 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.
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.

cont.
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
ON position.
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, section 6 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 display
is blank.
