INTRODUCTION
The ComfortChoice System is the industry-leading two-way
verifiable demand management solution. Using this unique
solution, your utility can remotely adjust the operation and
temperature of your air air conditioning or heating system,
for short periods of time during periods of peak energy
usage. You have the Choice to override (cancel) the
adjustment if needed, always keeping you in ultimate
control of your Comfort. ComfortChoice is a two-piece
solution consisting of a programmable thermostat and a
utility I/O board equipped with two-way radio communications. The programmable thermostat offers programming
options that allow you to set different cooling and heating
settings that will change automatically in accordance with
schedules that you set up to fit your particular lifestyle.
• Thermostat—Each installation has 1 thermostat. This
is the command center for the system.
• Utility I/O board—The Utility I/O board communicates
to the thermostat and provides 24 Vac outputs to the
cooling/heating equipment. The on-board two-way
radio provides system access via wireless radio
frequency communications.
• Auxiliary Load Controller—Optional component, not
supplied by Carrier, to facilitate utility auxiliary
curtailment or optionally control a residential device
remotely through combined wireless/internet capabil-
ity. Device is wired to the Utility I/O board.
INSTALLATION CONSIDERATIONS
These instructions cover the physical installation and start
up of the ComfortChoice system.
1. Install thermostat in non-condensing areas with ambients
between 30°F and 104°F (0°C to 40°C). Install the Utility I/
O board in non-condensing areas with ambients between
-4°F and 158°F (-20°C to 70°C). The auxiliary load
controller can be mounted outdoors if used with the
proper conduit fittings (follow local code requirements).
2. The use of separate isolated transformers is required if
the existing system transformer is less than 40 va. The
ComfortChoice system can be powered from the system
transformer in most applications. If the thermostat blanks
or the electronics turn off when the system is active
connect a separate (field supplied) 40 va class 2 isolation
transformer to the 24 Vac and C terminals to power the
electronics.
INSTALLATION
Step 1 — Check Equipment and Job Site
INSPECT EQUIPMENT—File claim with shipping company,
prior to installation, if shipment is damaged or incomplete.
Step 2 — Component Location and Wiring Considerations
WARNING
PERSONAL INJURY AND UNIT DAMAGE HAZARD
Failure to follow this warning could result in personal
injury and unit damage.
Disconnect power supply before routing wire.
All wiring must comply with national, local, and state
codes.
LOCATING UTILITY I/O BOARD
All wiring is run back to the ComfortChoice Utility I/O
board. Select a location near the furnace or fan coil where
wiring from the thermostat and the equipment itself can
come together easily.
The ComfortChoice I/O board and thermostat are approved
for indoor use only and should never be installed with
these components exposed to the elements. The Utility I/O
board may be installed in any area where the temperature
remains between -4°F and 158°F (-20°C to 70°F), and there
is no condensation. The cover must be installed to prevent
damage from other sources. Do not locate where it will be
accessible to children. Avoid areas in which the sound of
relays energizing on the Utility I/O board may
be an annoyance. The Utility I/O board should be mounted
with the antenna positioned vertically. Wiring access is
likely the most important consideration.
UNIT OPERATION AND SAFETY HAZARD
Failure to follow this caution may damage equipment.
To prevent possible damage to the Utility I/O board, do
not mount on plenum, duct work, or flush against
furnace or air handler.
LOCATING THERMOSTAT
The thermostat should be mounted:
• approximately 5 ft (1.5m) from floor.
• close to the center-preferably on an inside wall.
• on a section of wall without pipes or duct work.
2
!
CAUTION
!
Page 4
The thermostat should NOT be mounted:
• close to a window, on an outside wall, or next to a door
leading to the outside.
• where it will be exposed to direct light and heat from a
lamp, sun, fireplace, or other temperature-radiating
object which may cause a false reading.
• close to or in direct airflow from supply registers and
return-air grilles.
• in areas with poor air circulation, such as behind a door
or in an alcove.
WIRING CONSIDERATIONS
All wiring in the ComfortChoice system may be unshielded.
Ordinary thermostat wire is ideal for all connections. Use 22
gauge or larger for normal wiring. Lengths over 100 ft
should use 20 gauge or larger wire.
The thermostat requires 2 conductors.
The connection to equipment (furnace or fan coil) could
require as many as 8 conductors for a multi-stage installation. The optional outdoor air temperature (OAT) sensor
requires 2 conductors. The OAT sensor may be able to be
connected at the outdoor unit using existing wiring.
Cables with excess conductors are acceptable. Cut off or
fold back and tape any unneeded conductors.
Plan the routing of wiring early to avoid possible problems
later on.
Remember all wires converge at the Utility I/O board, so its
location is important.
Fig. 1 - Locking Tab Location
Step 3 — Install Components
INSTALL UTILITY I/O BOARD
The Utility I/O board is designed so that wires can enter it
from behind, above, or below. Plan wire routing before
mounting Utility I/O Board.
1. Remove cover to access mounting holes (remove the
system cover from the left side first).
2. Mount back plate to wall using screws and wall anchors
provided.
3. Level back plate and tighten screws.
4. Connect included antenna by screwing the threaded end
to the Utility I/O board radio.
INSTALL THERMOSTAT
CAUTION
!
EQUIPMENT DAMAGE AND SAFETY HAZARD
Failure to follow this caution WILL damage equipment.
Ensure that the system power is off. Disconnect
existing thermostat wires from existing thermostat and
equipment prior to connecting existing thermostat wires
to the ComfortChoice thermostat.
1. Turn off all power to equipment.
2. If an existing thermostat is being replaced:
a. Remove existing control from wall.
b. Disconnect wires from existing thermostat, one at a
time.
c. As each wire is disconnected, record wire color and
terminal marking.
3
Page 5
d. New or additional wires may be needed to accommo-
date added humidity outputs.
e. Discard or recycle old control.
3. Remove mounting plate from back of thermostat display
module by pressing the two tabs on the bottom edge and
pulling away. See Fig. 1. Figure 2 shows the mounting
plate removed from the module.
4. Route wires through large hole in mounting base. Level
mounting base against wall (for aesthetic purposes only
— the display module does not need be leveled for
proper operation) and mark wall through 2 mounting
holes. See Fig. 3.
5. Drill two 3/16-in. mounting holes in wall where marked.
Control may be mounted to a standard junction box, if
desired. Hole pattern on control mounting base matches
junction box mounting holes.
CAUTION
!
UNIT DAMAGE AND SAFETY HAZARD
Failure to follow this caution may damage equipment.
Improper wiring or installation may damage the thermo-
stat. Check to make sure wiring is correct before
proceeding with installation or turning on unit.
6 .Secure rear plastic mounting base to wall with 2 screws
and anchors provided. Additional mounting holes are
available for more secure mounting if needed. Make sure
all wires extend through hole in mounting base.
7. Adjust length and routing of each wire to reach proper
connector block and terminal on mounting base with 1/4in. extra wire.
8 .Connect two wires from the equipment control module to
the display module mounting base, being careful not to
over-tighten the screws. Correct polarity must be
observed when connecting the two wires. If wires are
connected incorrectly, the display module will not
operate.
See Fig. 4 and 5.
9. Connect red wire of the pigtail to V+ RED terminal.
Connect black wire of the pigtail to Vg BLACK terminal.
NOTE: The 2-wire pigtail is not intended to support the
weight of the thermostat. Do not hang the thermostat
from the equipment control module screw terminals.
10. Push any excess wire into wall and against mounting
base. Seal hole in wall to prevent air leaks. Leaks can
affect operation and cause incorrect temperature and/or
humidity measurement.
11. Attach 2-wire pigtail to display module. Pigtail is packed
loose in the box from the factory. Pigtail is attached to
the back of the display module via 2-pin, keyed connector.
12. Reattach display module body to mounting base by first
setting the module on at top of mounting base and then
snapping the bottom corners of display module into
place. See Fig. 6.

Step 4 — Final Wiring
UTILITY I/O BOARD WIRING
Bring all Utility I/O board wires together at Utility I/O
board. Make all connections as indicated in Fig. 7.
Figures 9 through 18 show the connection between the
Utility I/O board and the HVac equipment. Select proper
diagram for your equipment and connect accordingly. This
connection will require as few as 4 or as many as 7 conductors.
Fig. 8 - System Wiring
It is good practice to mark each wire as the final
connection is made. This will preserve its identity if it is
ever disconnected.
NOTE: Wiring diagrams appear near the end of this
document.
WIRING CONSIDERATIONS
ComfortChoice treats all furnaces as if they were 2-stage.
For single stage equipment, connect to W. The same holds
true for auxiliary heat in fan coils. With any 2-stage furnace,
configure the furnace so that low heat is controlled by W
and high heat is controlled by W and W2 together.
All 2-stage air conditioners and heat pumps need to be
configured so that Y controls low speed and Y and Y2
together control high speed in both heating and cooling.
POWER WIRING
The thermostat is powered by 24 Vac only. The
thermostat requires the 24 Vac (Rh and/or Rc and C
terminals) of the low-voltage transformer to be connected
to it for proper operation. The thermostat will not operate
without these connections. The Rh and Rc terminals are
connected via the PCB breakout jumper. For applications
using a single 24 Vac transformer for power, the breakout
jumper should remain intact. For applications using two 24
Vac transformers, the breakout jumper must be broken
because possible voltage differences between the two
transformers could cause irregular operation or damage to
the thermostat. See Figure 8. For applications using two 24
Vac transformers, one in the indoor unit and one in the
outdoor unit, connect the common wire from each to the C
terminal. Connect R from the indoor unit to the Rh terminal.
Connect R from the outdoor unit to the Rc terminal. Break
the jumper on the circuit board. See Figure 8. The W and
HUM signals are taken from the Rh power and the G signal
is taken from the Rc power. If the control has been installed
in a two-transformer application that is later changed to a
single-transformer installation, the installer must install a
field-supplied jumper between Rc and Rh. Depending on
the installation, up to 14 wires may be required. Installation
as two-piece unit is recommended. Only 2 wires are required
for connection between display module and equipment
control module. These two wires (V+ and Vg) do not
provide ordinary 24 Vac. They carry a combination of
power and communications data that is unique to these
products.
Step 5 — Understanding Sequence of Operations
TEMPERATURE SET POINTS
The ComfortChoice System uses 2 temperature set points,
the higher for cooling and the lower for heating. A minimum
difference of 2°F is normally enforced between heating and
cooling set points, although this value may be adjusted by
the installer. Each set point may be manually adjusted or
controlled by a programmed time schedule established by
the home owner.
The ComfortChoice thermostat can also be configured for
Heat Only or Cool Only operation. In these modes a single
set point is used to control a furnace (Heat Only) or an air
conditioner (Cool Only).
HEATING AND COOLING COMFORT SET POINTS
If space temperature is between heating and cooling set
points, then it is said to be “satisfied” with respect to
temperatures. When a space is satisfied, no heating or
cooling is required. When the space is satisfied, there is no
demand and the equipment is turned off. For example, if
cooling set point is 76°F and heating set point is 72°F,
then a space temperature of 73°F is assumed to be satisfactory and no heating or cooling of the space is required.
If space temperature falls below heating set point, then that
space needs to have heat added which will raise space
temperature back to heating set point. For example, if
heating set point is 72°F and space temperature is 70°F,
then space temperature must be raised 2°F in order for the
space to be satisfied. In this case, temperature “heating
demand” for zone is 2°F (72° minus 70°F). Otherwise, if
temperature in a space rises above cooling set point, then
that space needs to have heat removed which will lower
space temperature back to cooling set point. For example, if
cooling set point is 76°F and space temperature is 77°F,
space temperature must be lowered 1°F in order for space to
be satisfied. In this case, cooling demand for space is 1°
(77°minus 76°F).
Step 6 — System Configuration
Make sure this step is not left out.
The ComfortChoice thermostat must be configured to
match the type of equipment connected to it. There are
several choices of configuration based on how the user
wants the system to operate. Configuration is done by
setting the equipment type and other options in the
thermostat on power up. Configuration options enable the
installer to configure the thermostat for a particular
installation. Most options are not presented to the homeowner and therefore must be properly set by the installer.
Turn on power to the thermostat.

At power up the thermostat displays all segments for a few
seconds. Follow the instructions below to enter configuration mode and set the configuration options.
CONFIGURATION
To Enter and Exit Configuration Mode — Press
and hold the FAN button for approximately 10 seconds.
The display module will now be in Configuration mode. The
module will automatically exit this mode if no button is
pressed for 3 minutes. Pressing the DONE button will exit
Configuration mode immediately.
While in Configuration Mode — The option number is
displayed in the lower right corner of the display in the heat
set point location and the configuration setting is displayed
in the cool set point location. A box will surround the
option number. The MODE button is used to move the box
between the two displayed values or the softkeys below
the values may also be used. The value inside the box is
changed by using the UP or DOWN button. All changes
made are saved at the time of selection and will be saved in
the event of the 3-minute timeout or when installer exits
from configuration menu. See the table on the next page for
the list of configuration options. Each option is described
below.
Configuration Options
OPTION 01 — EQUIPMENT TYPE — Determines the
control method of the thermostat. It should match the type
of equipment used. Equipment Types are as follows: H2 Two speed Heat Pump with a fan coil, HP - Single speed

MODE — Changing the display from OF to SE using the up
or down button will initiate a wireless message to facilitate
end to end testing of the wireless connection. The thermostat will communicate to the Utility I/O board to send a
wireless message to the server. The Utility I/O board will
monitor the status of the message and send this information back to the thermostat. When a test message is in
progress, “SE” will be shown in the room temperature
display followed by "LI". The clock display will increment
indicating how long the test has been in progress. If the
test message was successfully sent and received by the
wireless connection, “PAS” will be displayed in the clock
location. If the message was not successfully sent and
received, F1 or F2 will be displayed in the clock location.
(F1—cannot send message; F2—message sent, no reply.)
The installer can cancel the self test at any time by pressing
the up/down button and changing the room air display to
OF. To initiate another test, the setting must be set back to
SE. Allowable selections are OF (off) and SE (serial test).
Use UP or DOWN button to select between OF (off) and SE
(serial test). The default is OF (off).
OPTION 21 — KEYPAD LOCKOUT — This selection

When the keypad is unlocked, the padlock icon will turn
off. The keypad will remain unlocked for two minutes after
the last button press. After two minutes with no button
presses, the keypad will lock again. The keypad will not
lock in the software configuration mode or in the installer
test mode. The default is OF (off).
OPTION 22 — AUTO CHANGEOVER TIME — This
selection is not available on Heat Only and Cool Only
systems. The system must have no demand in the current
mode for the selected number of minutes before the AUTO
mode will be allowed to change between heating and
cooling or vice versa. Allowable selections are 5, 10, 15, 20,
25, 30 minutes. The default is 30.
OPTION 26 — MINIMUM COOLING SET POINT —
This selection allows the installer to configure the minimum
cooling set point that the user is allowed to set. The range
takes into account the value of the adjustable deadband
Option 11. The range is 50°F (plus the adjustable
deadband) to 90°F. The default is 52°F (based on the
adjustable deadband default of 2).
OPTION 27 — MAXIMUM HEATING SET POINT —
This selection allows the installer to configure the maximum
heating set point. The range is based on the adjustable
deadband value Option 11. The range is 50°F to 90°F minus
the deadband. The default is 88°F (based on the adjustable
deadband default of 2).
OPTION 33 — SINGLE OR TWO-PIECE INSTALLATION

future use. The default is 1P.
OPTION 99 — RESET TO FACTORY DEFAULTS — Use
this capability to reset the control to “out of the box”
conditions.
IMPORTANT: All configuration settings, program
settings, clock, and calendar settings which have been
manually entered will be lost and reset.
When this option is selected, the number 99 will appear in
the cool set point location (left) and the number 10 will
appear in the heat set point location (right). To perform the
reset, first use the MODE button to move the box from the
99 to the 10. Press and hold the DOWN button. The 10 will
start counting down toward zero. If the DOWN button is
kept pressed until the count reaches zero, the reset will be
performed. When the value reaches zero, the heat set point
will display “-.” The cool set point will display “-” and the
air temperature will display “Fd.” When the factory defaults
have been restored, the thermostat will act as if power was
cycled and return to normal operation. If the DOWN button
is released early, the number will return to 10 and the reset
will not occur. After the reset, the installer should enter the
installer configuration to verify that it is configured for the
8
thermostat application.

Step 7 — System Startup and Checkout
INSTALLER TEST
The thermostat is designed with a built-in installer test
capability. It allows easy operation of equipment without
delays or set point adjustments to force heating or cooling.
To enable installer test mode, press and hold the FAN
button for 15 seconds. The control will enter configuration
mode. Continuing to hold the FAN button will cause the
thermostat to enter installer test mode. IN ST will be
displayed in the heat and cool set point location. Pressing
the MODE button will change the system operating mode
to test the heating and cooling equipment. The Auto mode
is not available during installer test mode. If no buttons are
pressed for 15 minutes, the installer test mode will be
terminated. Pressing DONE at any time will exit installer test
mode.
HEATING — The first stage of heating will be energized for
3 minutes, then the first and second stages will turn on for
an additional 3 minutes. During the first stage of heating,
the HEAT ON icon will be displayed. During the second
stage of heating, the “2” next to the “On” will be displayed.
COOLING — Installer test for cooling is the same as
described for heating above. The COOL ON will be
displayed during cooling in installer test mode. When the
mode is set to “em heat,” the auxiliary heat will turn on for 3
minutes. The clock display will count down from 180 to 0
during this test.
TO TEST FAN — Pressing the FAN button will switch the
triangle icon between AUTO and ON. While ON is displayed, the G output will be energized, turning the fan on.
Allow up to 10 seconds after the button is pressed for the
fan to turn On and Off. On some fan coils, the fan continues
to operate for 90 seconds after the G sifnal is removed.
TO TEST AUXILIARY RELAY (IF EQUIPPED) — Use the
MODE button to set the system to OFF and then press the
SET button to toggle the auxiliary relay. The AUXILIARY
icon will be displayed when the relay is energized. When
the mode is set to HEAT or COOL during the installer test,
the auxiliary relay will be de-energized.
Final Settings
Be sure to press DONE to exit installer setup mode. If the
system is to be left in operation after installation is complete, use MODE button to select between HEAT, COOL,
AUTO, or EM HEAT to provide desired operation.
Default Schedule
If the programmed schedule is to be used, make sure the
triangle icon appears before the FOLLOW SCHEDULE icon.
The default schedule is shown in Table 1. Pressing the
Schedule button will cycle the triangle icon through the
FOLLOW SCHEDULE, HOLD and VacATION selections. If
fixed temperatures are desired, use SCHEDULE button to
turn on the triangle icon next to HOLD. This will maintain
set points, not allowing them to change with programmed
schedule. Use the FAN button to select between AUTO
(fan on only with equipment) and On (fan on continuously)
fan modes.
OPERATIONAL INFORMATION
Five-minute Compressor Timeguard
This timer prevents the compressor from starting unless it
has been off for at least 5 minutes. It can be defeated for 1
cycle by simultaneously pressing the FAN button and the
UP button. It is not active in the installer setup mode.
Cycle Timer
Based on the selection of 2, 4, or 6 cycles per hour, this
timer is set to 30, 15, or 10 minutes. This time must elapse
from the start of one cycle before another cycle can be
defeated for one cycle by simultaneously pressing the FAN
and UP buttons.
Ten-Minute Staging Timer
In multistage heating or cooling this timer prevents any
higher stage from coming on until the previous stage has
been on for 10 minutes. When staging between compressor
and electric heat or between compressor and furnace heat,
the time is configurable. The timer is configurable via
Option 17. This timer is overridden if temperature error is
greater than 5°F (usually due to a large change in desired
temperature) and equipment stages up in 60 second
intervals.
Three-Minute Minimum On Time
When a cooling or heating stage is turned on, it will remain
on for at least 3 minutes. These timers are canceled when
set points are changed.
Heat/Cool Set Point Difference
A minimum difference of 1°F and 6°F is enforced between
heating and cooling desired temperatures (set points). This
deadband is maintained by allowing one set point to
“push” the other to maintain the required minimum difference. This difference is adjustable via configuration Option
11.

Table 1 – Default Program Schedule
Equipment On Indicators — When cooling equipment
is on, a COOL ON icon is displayed. While cooling
equipment operation is delayed by the time guard or cycle
timer, COOL ON will flash. The same is true for HEAT ON
icon. During second stage compressor operation a “2” will
be displayed with the HEAT ON or COOL ON icon. When
the W is energized in a heat pump or emergency heat is
available the “AUXILIARY HEAT ON” icon will be
displayed.
Auto Changeover
When the auto changeover mode is selected, a change from
heat to cool or cool to heat will not occur until an opposite
mode demand has existing for the number of minutes
specified by configuration Option 22. If the set point is
changed, the specified time requirement is deleted.
Emergency Heat Mode
When the system is configured for a heat pump and
EHEAT mode is selected, Y outputs are disabled and W
outputs only are used for heat.

PIN Number Display
The wireless modem PIN number may be displayed by
pressing the SET button and then pressing and holding the
soft key below the Hours value for 10 seconds until the
display goes blank. The PIN number will then be displayed
across the room air, cool set point and clock locations. The
thermostat will return to normal operation after 15 seconds.
NOTE: The PIN number will not be displayed if in software
configuration, installer test or programming modes.
Other Messages
HEAT ON, COOL ON — The HEAT ON and COOL ON
icons, which are located under the two set point displays,
indicate when cooling or heating equipment is actually
operating. When the icons flash, equipment is waiting to
come on but is being held off by compressor timeguard or
cycle timer.
The triangle icon appears before the fan mode ON icon.
During an unoccupied mode (DAY, SLEEP) the fan
selection will be allowed to change from AUTO to ON, but
when ON is selected and the equipment is not running, the
triangle icon will appear before the ON icon. This is a
feedback to the user that the fan is not running because the
current period is unoccupied and the equipment is not
running.
Outputs vs. Stages
Table 2 above lists the active outputs for each stage of
each possible system configuration. G is not shown. For 1stage furnaces and auxiliary heat, connect to W and leave
W2 open. For single speed compressors, connect to Y and
leave Y2 open.
Step 8 - Thermostat Programming - Overview
QUICK START
This quick start procedure provides an overview of
programming in order for you to begin to use your system.
For the best comfort and energy-saving results and detailed
thermostat operating instructions, we recommend that you
read through the ComfortChoice Edge Owner’s Manual,
which is included in the box along with your thermostat,
and set up the system to match the end-user’s specific
schedule and comfort requirements.
Setting the Clock, Calendar, Daily Schedule,
and Vacation Settings
The thermostat communicates wirelessly with a communication network and it automatically obtains the current time
and date from the communication network. In the event of
loss of network communication, you can manually set the
time and date by following the instructions below.
To set the clock:
Press and release the SET button until ...clock is displayed
in the left center of the display along with the time at the
bottom center of the screen. Use the softkeys to move the
box around the digits to be set and use the UP or DOWN
button to change the setting.
To set the daily schedule:
Pressing the SET button will cycle through ...clock, ...daily
schedule and ...vacation settings. When changing daily
schedule settings, the softkeys are used to set the days,
period times, heating set points, and cooling set points.
The UP and DOWN buttons are used to change the setting
with the box around it. All program periods (WAKE, DAY,
EVE, and SLEEP) must occur within the same 24-hour
period.
Vacation schedule: When changing Vacation settings, the
softkeys are used to choose the selection to be adjusted
and the UP or DOWN button is used to change the setting.
A Vacation selection is available specifically for times when
the space will not be occupied for an extended period.
Vacation mode has an automatic hold, meaning that set
points are not affected by the programmed schedule.
Vacation mode is active for a specified period of time. While
in Vacation mode, the system provides temperature
protection for the space in the selected mode, but not
comfort. When Vacation mode is active, the triangle icon
will be displayed before the VACATION in the upper left
corner of the display.
Vacation Set Points — A default set of temperature and
humidity set points are active in Vacation mode. They are
adjustable by the user and are used exclusively for Vacation mode. They are remembered from one Vacation
selection to the next. See Table 3 below for default Vacation
values.

TROUBLESHOOTING
If the thermostat display does not power up after power is
applied, check the Rc/Rh and C terminals for 24 Vac. If 24
Vac is present, check the voltage between Vg and V+. This
voltage will be approximately 12 to 20 Vdc. If voltage is
present, check the polarity to make sure it is wired correctly.
The display will not power up if polarity is reversed. Table 2
can be used as a troubleshooting tool for determining
which outputs will be active for a particular configuration
and each operating mode.

Error Codes
“--” — Thermistor failure
Temperature sensing element in the thermostat cannot
properly read room temperature. All outputs (except fan,
if set to on) will turn off. The thermostat must be replaced. In the case where the installer has selected to
average the local sensor and the remote sensor, the
display will alternate between “--” for the failed sensor
and the temperature sensed by the working sensor every
10 seconds. The thermostatl will operate from the
temperature sensed by the working sensor.
E1 — The thermostat and the I/O board cannot communicate via two-wire connection.
E4 — Internal memory failure. When this error is present
and power is cycled to the thermostat all of the installer
configurations, program schedule settings and user
settings will be factory default values. Replace the
thermostat.
I/O Board Error Codes —
Error codes for the I/O board are indicated by the flash rate
of the on board LED. The slow flash rate is the first digit,
and the fast flash rate is the second. During normal
operation the flash rate of the LED will be 1 second on, 1
second off.
23—Flash Memory Error. Replace the I/O Board.
25—EEProm (Memory) Error. Replace the I/O board.
27—RAM Memory Error. Replace the I/O Board.
32—Device out of range. Check antenna connection.
34—No communications with thermostat. Check connec-
tions between the I/O board and the thermostat.
36—No communications with the Radio. Check cable
connection between the thermostat radio and the I/O
board.
