- My
heating or cooling does not work. What can I do?
No Heat: With the system set to
heat, when the setpoint temperature is raised or lowered
past the room temperature, the thermostat will make
a soft click sound within about 5 seconds. Usually
the sound indicates correct thermostat operation.
If the heat does not come on after raising the temperature
and hearing the click, check the fuses or breakers,
make sure the furnace is switched on, verify the blower
compartment door is closed properly and if your furnace
has a pilot verify that the pilot is lit. If no click
sound is heard try resetting the thermostat as described
below. If the no heat or no cool condition persists
after resetting the thermostat, you may wish to contact
your heating/cooling service person for assistance.
No Cool: Air conditioning systems usually include
an outdoor compressor and an indoor blower. With
the thermostat set to COOL and the temperature lowered
below the room temperature by a couple of
degrees there can be up to a five minute delay before
the thermostat activates the compressor and an
indoor blower. If both the compressor and an indoor
blower are running and the air is not cool it may
indicate loss of refrigerant in the compressor. If
the blower or compressor do not come on or do not
shut off, try resetting the thermostat. If the no
heat or no cool condition persists after resetting
the
thermostat, you may wish to contact your heating/cooling
service person for assistance.

- My
thermostat is reading in Celsius. How do I change it
to Fahrenheit?
Your
thermostat display can be set to display temperature
in Fahrenheit or Celsius. Refer to your instructions
under Installation/Configuration Menu.

- My
thermostat does not display the temperature my thermometer
reads. Is there an adjustment to change the display?
Yes.
The thermometer can be adjusted +/- 4 degrees as listed
in the Installation/Configuration Menu.

- How
often should I replace the batteries in my thermostat?
For optimum
performance we recommend that you replace the batteries
once a year with "AA" Alkaline batteries.
back to top
- How
do I bypass (not use) the program?
The
thermostat can hold any temperature within it's range
for an indefinite period without reverting to the
programmed temperature. Momentarily press the HOLD
button. HOLD will be displayed. Then choose the desired
temperature by pressing the temperature UP or temperature
DOWN arrow. The thermostat will hold the room temperature
at the selected setting until you press the RUN button
to start program operation again.
back to top
- My
furnace (air conditioning) cycles too fast (slow). Is
there an adjustment?
Adjustable Heating
Cycle Times (also called Anticipation). Cooling is
not adjustable.
Your thermostat is designed to cycle on and off in
heating or cooling, keeping your building in an accurate
temperature range. This maximizes your comfort by
keeping the room temperature very close to the temperature
you set. It is not unusual for your thermostat to
be set for 70 and cycle on and off at 70 keeping you
right on target. Your Comfort-Set 80 Series thermostats
have an option that allows you to select a fast or
slow heating cycle rate.
A note on older style thermostats: Anticipation on
older style thermostats (mercury bulb or mechanical)
used the current draw of the equipment to set the
anticipation. Some heating and cooling equipment manufacturers
still refer to setting the anticipator to the current
draw of the equipment. This does not apply to your
new digital thermostat. Right from the box your new
thermostat will do an excellent job of keeping your
building at an accurate temperature. The information
above allows you to customize the performance of your
digital thermostat to your requirements.

- Why
won't the thermostat bring on second (and/or third)
stage heat or cool?
1F8X-XXX Series Multi-stage and
Heat Pump thermostats are designed to determine the
optimum time to activate the second stage. Simply
raising the temperature in heating or lowering it
in cooling will not always force the thermostat to
bring the second stage on quickly. There is a time
delay from 0-30 minutes. The time element (0-30 minutes)
of the delay varies depending on the performance of
the first stage. In Heating for example, assume for
the last 2 hours the thermostat is set on 70 and the
room temperature is 70 with the equipment using only
the first stage of heat. The thermostat calculates
(internally) the performance of the system. Since
the equipment is keeping the temperature within 1
degree of setpoint the thermostat will delay second
stage for a longer time if you manually raise the
temperature or if the room temperature quickly changes.
Once the second stage comes on it will come on sooner
the next time there is a difference between the setpoint
and the room temperature. The net effect of the staging
program is when the first stage is capable of making
temperature the second stage will delay longer. When
the thermostat calculates first stage cannot make
temperature in a reasonable time the second stage
will come on sooner. This is a built in function that
automatically optimizes the use of additional stages
of heat or cool. Most thermostat models have a method
to bring the additional heat or cool stages on quickly
for testing purposes listed in the installation instructions
under the heading of “Testing Your Heat/Cool System”.

- Do
I have to program a stop time for each program period?
There is no need to select a time to stop a programming
period. Starting a new programming period will stop
the previous program period.
back to top
- My
thermostat does not follow its program. What should
I do?
Unless
the thermostat appears to be damaged it will follow
the program that is in the memory. The most common
reason a thermostat will appear not to be following
it's program is a program error. Verify that the AM
or PM settings are correct for each period. Also verify
that the Day of the week is set correctly. Models
with EMR (Energy Management Recovery) start early
to make the temperature they are programmed for by
the time specified in the program. See the Configuration
Menu of your thermostat Operating Instructions for
information on how to disable EMR if you do not want
the thermostat to start early.

- Between
heating and cooling seasons, I want to turn my system
off. Will this change my program?
Any time you wish to turn your system off, simply
slide the SYSTEM switch to the OFF position or push
the SYSTEM button until OFF is displayed. This will
not affect your thermostat's programming in any way.
back to top
- Why
does the blower fan keep running after the system has
shut off?
Possible short in wiring, Check each wire connection
to verify they are not shorted or touching together.
Possible short in thermostat, no bare wire should
stick out from under terminal screws. Fan Switch slid
to Fan On, or FAN button pushed to display FAN ON.
If the condition persists, the manufacturer of your
system or service person can instruct you on how to
test the Heat/Cool system for correct operation. If
the system operates correctly, replace the thermostat.
back to top
- My
display light does not work. Can it be fixed or replaced?
The display
light in the 1F80 series is not a replaceable item.
On single stage thermostats (1-heat/1-cool)
the light uses battery power. If the light is not
coming on, replace the batteries and/or clean the
battery
contacts inside the back of the thermostat. Use a
pencil eraser to gently polish each of the battery
contacts. Do not bend them up and down or they may
break. When complete they should be as shiny as a
mirror. This will assure proper battery back-up and
allow the backlight to work correctly. The multi-stage
and heat pump models obtain power for the light from
the 24 volt transformer so if anything in the system
interrupts power to the thermostat the light will
not operate.
back to top
- Do
I have to reprogram my thermostat after I change the
batteries?
No. This thermostat has permanent memory, although
you will have to reset your clock.
back to top
- What
do I do if my thermostat has a blank display or my keypad
is not responding?
If
a voltage spike or static discharge blanks out the
display or causes erratic thermostat operation you
can reset the thermostat by pressing the UP arrow,
DOWN arrow and move the SYSTEM switch from OFF to
HEAT at the same time.
back to top
- My
flame (snowflake) icon is flashing. What does this mean?
The
Snowflake icon is displayed (flashing) if the thermostat
is in lockout mode to prevent the compressor from
cycling too quickly. The Flame and Snowflake icons
flashing simultaneously on the 1F82-261 & 1F89-211
models indicate a Compressor Lockout. Also the Flame
icon flashing on its own in the heat mode for both
models indicates that Auxiliary Heat is energized.
back to top
- Is
my thermostat compatible with a boiler system?
On the
front page of your instructions under SPECIFICATIONS
(APPLICATIONS) there is a listing of compatible systems
that this thermostat can be used on.
back to top
- My
setpoint temperature is flashing. What does this mean?
When
the thermostat compressor time delay occurs it will
flash the setpoint for about five minutes. This is
intended to help protect the compressor from short
cycling.
back to top
- What
does a flashing L mean on my display?
The
L icon means that you either have your HEAT/COOL or
both limited ranges set. The L icon flashes to indicate
the Limit was trying to be exceeded.
back to top
- Why
does my system run with setpoint and room temperature
the same?
In
cooling, as the room temperature falls you will eventually
reach the setpoint temperature. The system will continue
to run until it reaches the low side of the temperature
setting. As an example: If set to 78° with the
room temperature falling the thermostat will continue
to call for cool as the temperature decreases in the
following manner. 78.9 °, 78.8 °, 78.7 °,
78.6 °, 78.5 °, 78.4 °, 78.3 °, 78.2
°. At approximately 78.2 ° the thermostat
will quit calling for cool. This is why it is not
unusual for the room temperature and set temperature
to read the same but the system continues to run.
The amount of time it takes for the system to shut
off is dependent on system sizing, thermostat location,
etc. Note: The thermostat display only displays whole
numbers. Internally the thermostat calculates decimals.
In heating as the room temperature increases the system
will continue to run until the thermostat reaches
the high side of the temperature setpoint.

- My
thermostat is resetting on its own. How can I resolve
this problem?
For
Single Stage models there are 3 possibilities to consider
(excluding tampering):
Loss of power from the system and
back-up batteries not functioning.
You may want to see if the thermostat maintains the
display when removed from the subbase to
determine if the batteries are functioning on power
loss. You may want to check the fuses or breakers,
the on/off switch on the furnace and the door to the
blower compartment. If the blower compartment door
is loose there may be a switch inside the door that
disconnects power to your system. Also consult the
furnace manufacturer to see if they have any other
ideas on what could drop out the system power.
Static electricity or a voltage
spike from the heating equipment might be
resetting the thermostat. Static electricity can be
eliminated by touching something before touching the
thermostat to dissipate the static charge. A voltage
spike from the equipment can be eliminated using an
isolation relay as described in the link below.
http://www.white-rodgers.com/pdfs/instruction_sheets/0037_5426_A.pdf
You can also check the wire routing to verify the
thermostat or remote wires are not running parallel
to High voltage lines with high inductive loads that
could (in extreme cases) create a voltage spike at
the thermostat.
For Multi-Stage or Heat Pump staging models
there are other possibilities to consider and they
are as follows:
Loss of power from the system. You
may want to check the fuses or breakers, the on/off
switch on the furnace and the door to the blower compartment.
If the blower compartment door is loose there may
be a switch inside the door that disconnects power
to your system. Also consult the furnace manufacturer
to see if they have any other ideas on what could
drop out the system power.
Static electricity can be eliminated
by touching something before touching the thermostat
to dissipate the static charge.
A voltage spike from the heating
equipment might be resetting the thermostat and if
you have a system that generates a high voltage spark
(D.S.I.) you may want to contact the Equipment manufacturer
for information on how to eliminate that condition.
You can check the wire routing to verify the thermostat
or remote wires are not running parallel to high voltage
lines with high inductive loads that could (in extreme
cases) create a voltage spike at the thermostat.

- What
do AUX, EMER, and MALF indicators mean on my Heat Pump
thermostat?
AUX
- Auxiliary Heat or the second stage of heat in the
Heat mode. This is energized when the Heat
Pump is not keeping up with the thermostat setting.
It is normal operation with most pumps for the
thermostat to call for auxiliary heat.
EMER - Emergency Heat. When switched to Emergency
the thermostat bypasses the pump and uses the back-up
heat. This is useful if the pump is not operating
correctly or if the temperature outside is so cold
that the pump is not economical to run.
MALF - Malfunction. Malfunction indicates the heat
pump system is sending a signal to the Malfunction
Indicator on the thermostat terminal marked “L”. It
does not indicate a malfunction in the thermostat.
The manufacturer of the Heat Pump system can determine
the likely cause of malfunction indication on the
thermostat.
