2 Installation
Replacing Existing Thermostat
Most existing thermostats have three parts:
• The cover, which may snap or hinge over the existing thermostat.
• The electronics or body, which controls the existing system.
• The sub-base, where the wires attach through the wall to the existing system.
1. Always turn off power to the air conditioning and heating system prior to
removing existing thermostat.
2. Carefully remove the cover and electronics body from the old thermostat
sub-base. Depending on the brand, these parts may pull off or need to be
unscrewed. The old sub-base should remain wired and on the wall until
steps 4 and 5.
3. Label every old wire with the letter of the connection to which the wire is
attached. Example letters are R, M, Y, etc. Depending on the brand of the
old thermostat, your letters may be different. (continued on page 2)

4. After labeling the old wires, loosen each connection and remove them from
old sub-base. Secure the wires to prevent them from slipping into the opening
in the wall.
5. Remove the old sub-base from the wall, again being careful that the wires do
not slip into the opening in the wall.
6. Use the chart on page 1 to determine the new thermostat connections. As an
example, if the old thermostat had a G or F connection, it goes to G on the new
thermostat. It may be helpful to use the chart by circling (with a pencil or pen)
the letter of each wire removed from the old thermostat.
11. Flip the front thermostat cover up and open the battery compartment door.
12. Locate the positive [+] ends of the batteries and match them with the positive
[+] terminals located in the battery compartment. Install the two new “AA”
alkaline batteries (supplied). Close battery compartment door.
13. Restore system power and proceed to programming and system checkout.
3 Quick Reference
NOTE: This thermostat is designed for use on low voltage 24 volt AC single stage
or multi-stage systems, including heat pumps with up to three stages of heating
and two stages of cooling. Do not use this thermostat on systems with voltage
higher than 30 Volts AC. This thermostat requires a transformer common wire for
proper installation if used as a hardwired thermostat.

NOTE: When installing this thermostat in a new location, following a few simple
guidelines and the applicable building codes will give the best results. Install the
thermostat in a location that provides good airflow by avoiding areas behind
doors, near corners, air vents, direct sunlight or heat generating devices. The
wiring must conform to all building codes and ordinances as required by local
and national code authorities having jurisdiction for this installation.
1. Always turn off the power to the air conditioning and heating system prior
to installing this thermostat.
2. Locate the release latch on the bottom (not the back) of the thermostat.
Press the release latch in and separate the body from the sub-base of the
thermostat. Because this thermostat has 15 possible connection points, you
may need to apply moderate force to separate the parts.
3. Set the thermostat electronics and cover down on a clean surface. Place the
sub-base on the wall in the desired location.
4. Using the slotted mounting holes in the sub-base, mark the placement of the
mounting holes through the slots and onto the wall. Ensure the wires come out
of the wall into the center hole of the sub-base.
5. After verifying the drill will not damage items in the wall, use a 3/16 drill to
create the mounting holes. Gently tap the supplied plastic anchors into the
holes in the wall.
6. Place the thermostat sub-base against the wall in the desired location. Ensure
the thermostat is level, the wires are inserted in the opening, and the mounting
holes are aligned with the slots on the sub-base.
7. Fasten sub-base to wall using supplied screws into the plastic wall anchors.
8. Connect wires to the quick wiring terminal blocks. Use the wiring diagram
chart to ensure the old and new connections are correct.
9. To prevent electrical shorts and potential damage to the thermostat, make
sure all wire connections are secure and not touching each other.
10.Locate the thermostat body, and ensure the cover is still installed properly.
Using the mounting tabs on the top of the sub-base as a guide or hinge, close
up the thermostat case by pivoting the body and cover closed. The latch on the
bottom of the thermostat will click when the case is properly closed. Because
this thermostat has 15 possible connection points, you may need to apply
moderate force to close the case. (continued on page 3)

Outside Air Intake Options of None
(disabled), Economizer Mode and
Time of Day Mode.
1. Selects Residential or Commercial (BUS) profile. Determines programming
events per day. If Residential is selected, 4 events per day are available. If
Commercial is selected, 2 events per day are available. Only the 7 day
programmable mode is available for the Commercial profile.
2. Selects the programming mode, either full 7 day or 5-2 day (weekdayweekend) programming or non-programmable. If the Commercial profile was
selected in step 1 this option is not available.
3. Selects either a 12 hour or 24 hour clock.
4. Selects preferred temperature scale of either ºF or ºC.
5. Selects Auto Changeover on or off. When off is selected, the AUTO icon
will not be displayed when selecting the system options with the system
switch. When Auto Changeover mode is enabled and selected, the system
automatically switches between heating and cooling when the room
temperature meets the programmed heating or cooling set points.
6. Selects single stage conventional (11C), 2 stage conventional (22C), single
stage heat pump (11HP), 2 stage heat pump (22HP), or 3 stage heat pump
(32HP). Any change made to the system type resets Installer Options 7 through
11 to their default values dependent on system selected.
7. Selects between 1st stage gas or electric heat Fan Control. This Installer
Option is not available with a heat pump system.
8. Selects aux-stage gas or electric heat Fan Control. This Installer Option is only
available with a 2 or 3 stage heat pump system.
9. For heat pump units with an electric auxiliary stage, both the first and second
stages of heating will run when a call for second stage heat is made. For heat
pump units with a fossil fuel auxiliary stage, the compressor stage(s) will be
locked out one minute after a second stage heat call, and the second stage
will only be used.

4 Programming Installer Settings cont.
10. Select between turning the AC power interrupt warning off or on. During a
power loss, the thermostat will display an outage warning. The system clock
will continue to run, and all settings will be maintained until the outage period
is over. This Installer Option is only available when thermostat is installed as
a hardwired unit.
11. This thermostat provides cold weather compressor protection by locking out
the compressor stage (1st stage) of heating for a period of time after a power
outage greater than 60 minutes. The lockout period is one hour less than the
outage time, up to a maximum of 12 hours. During that period of time, the
auxiliary heat stage will still be available to maintain the set point temperature.
The compressor lockout can be disabled by setting this option to OFF.
12. This thermostat includes an automatic compressor protection feature to
avoid potential damage to the cooling system from short cycling. This
thermostat automatically provides an adjustable delay after turning off the
cooling system output to protect the compressor. This protection is also present
in the heat mode of operation on single stage heat pump systems to protect
the compressor.
13. During the COOL mode of normal operation the fan will stay on for 60 seconds
after the cooling system has satisfied the set point temperature and has turned
off the compressor. This allows the system to provide higher efficiency during
cooling operation.The delay is selectable between 0, 30, 60 or 90 seconds.
14. The Recirculating Fan can be “locked on”, so that the only fan selections
available to the user are CIRC and ON. The Recirculating Fan Mode provides
more even temperature distribution and improves indoor air quality by
circulating air through the furnace filtration system more often. By locking the
Recirculating Fan on, the user will only have the option to run the fan all the
time (ON) or use the Recirculating Fan Feature (CIRC). If the Recirculating Fan
lock is set to off, the thermostat is put into the Recirculating Fan Mode by
pressing the FAN button until the CIRC icon is displayed. If no call for heating or
cooling occurs within the fan off cycle set in the User Options (see User Manual),
the fan will run for 24 minutes. When the fan lock is set to on, the highest
setting, 120 minutes, will run the fan least often – 9% minimum running time.
The lowest setting, 24 minutes (factory default), will run the fan most often –
33% minimum running time. The Recirculating Fan feature is available in the
COOL, OFF, HEAT, or EMER mode.
15. Enables or disables the ARM™ feature. During ARM™, room temperature is
recovered gradually by turning on the heating or cooling before the end of the
set back period. In a multi-stage configuration, room temperature is recovered
gradually by using only the first stage heating or cooling until the last 20
minutes, to minimize the use of the 2nd stage heating or cooling. The set point
temperature is changed to that of the upcoming comfort program temperature.
The start time of recovery is based on the difference between the current room
temperature and the upcoming comfort program set point temperature. The
recovery to the upcoming heating set point starts 10 minutes before the
upcoming set point time for each degree of temperature change required, up to
a maximum of 2 hours. The recovery to the upcoming cooling set point starts 15
minutes before the upcoming set point time for each degree of temperature
change required, up to a maximum of 3 hours. ARM™ does not operate when
the unit is in the temporary or permanent HOLD mode or if the program is
temporarily overridden or if emergency heat is selected for multi-stage heat
pumps. If the ARM™ feature is disabled the thermostat will recover the set point
temperature at the programmed set point time after the setback period ends.

4 Programming Installer Settings cont.
16. If a Braeburn® indoor or outdoor remote sensor is connected during
installation, the thermostat will automatically detect the type of sensor. When
an indoor sensor is detected, you may select between internal (sensI), external
(sensE), or averaging (sensA) of internal and external for temperature control.
When an outdoor sensor is automatically detected, the thermostat will remove
the choices for indoor sensing from the menu and enable outdoor measurement. The outdoor sensor may be used to determine if balance points have
been exceeded, for outdoor temperature dependent humidity control, and
outdoor temperature display. For proper auto-detection, you must use a
Braeburn brand external sensor. Should the external sensor become unwired,
the thermostat will retain the settings, but the balance points, temperature
dependent humidity control, and outdoor temperature display will be disabled
until the external sensor is repaired. Test the operation of the external sensor
by pressing the PROG and HOLD buttons at the same time.

17. The keypad lockout feature has two levels of security. Level one locks all
buttons (including the reset) except for the , and backlight buttons. Level
2 locks the entire keypad except the backlight button. The and buttons
can be pressed together to enter the lock code but the buttons do not work
individually to adjust the temperature. The lock level is set during the Installer
Options and the lock code is set in the User Options. See the User Manual,
Section 2.
18. Selects between disabling humidification (NONE), manual control (DEP), or
independent control (IND). The DEP setting controls humidification only during
heating calls. The IND setting allows humidification output in the heat mode,
but does not require a heat call. Braeburn recommends that the IND setting
only be used with systems designed for low air temperature humidification
such as steam humidification. Always ensure the heat exchanger or other
system parts are NOT exposed to excess water from condensation or other
sources. When there is any doubt, use the NONE or DEP setting.
19. Only available if outdoor sensor is connected and humidification is enabled.
Select between turning the Automatic Humidity Set Point limit OFF or ON.
Selecting OFF lets you set the Automatic Humidity Set Point manually. Selecting
ON limits the automatic set point which reduces the chance of condensation
on windows.
20. Enables or disables Dehumidification.
21. Zero stage dehumidification differential selects the number of degrees the
system is allowed to over-cool in attempting to reduce humidity. Options
available when dehumidification is enabled are 1˚, 2˚, or 3˚ F. (continued)

4 Programming Installer Settings cont.
22. Feature accommodates either a normally open relay or a normally closed relay.
Selects between Dehumidification fan speed limiting off (NO), or on: D output
normally active (NA) and D output normally inactive (NI).
23. When Auto Changeover mode is enabled and selected, the system automatically
switches between heating and cooling when the room temperature meets the
normal criteria for either a heating or cooling call. There is a forced separation
(dead band) between the heating and cooling set points, so the systems do not
work against each other. This option selects Auto Changeover Dead Band of 2º,
3º, 4º or 5º F. The default is 3º F unless dehumidification is enabled. When
dehumidification is enabled, the deadbands are as follows:
