INTRODUCTION
Bryant’s 7--day, 5/2--day, 1--day programmable and non--programmable
Preferredt Series Thermostat Control is a wall--mounted, low--voltage control
which combines temperature and humidity control in either a single unit or a
two--piece unit. In two--piece configuration, the relays are located near the
equipment and a two--wire connection is used between the Display Module and
the Equipment Control Module. Single--piece installation requires more wiring
and results in a higher profile. The Preferred Series Thermostat has no need for
batteries to store user--configured settings in memory. During power loss its
internal memory saves settings for unlimited time, and the clock continues to run
for at least 24 hours. An extension of Bryant’s proven line of thermostats; it
provides separate setpoints for heating and cooling in addition to humidification
and dehumidification.
In the control’s programmable configuration, different heating and cooling
setpoints and times are programmable for 4 periods per day or 2 periods per day.
Programming can be done for 7 days per week, 5/2 days per week, or 1 day. The
programmable Thermostat Control can also be user configured as a
non-- programmable Thermostat Control. When operating as non--programmable,
the Preferred Series Thermostat Control will still have both temperature and
humidity control.
The non --programmable Thermostat Control features Touch ’N’ Got settings
for quick and easy temperature change without complicated programming
schedules. The non-- programmable Preferred Series Thermostat Control will still
have both temperature and humidity control. And, its Touch ’N’ Go technology
enables the user to switch between three different user--configurable settings
through intuitive buttons located just below the display.

INSTALLATION CONSIDERATIONS
Power
This control is powered by 24VAC only. It requires 24VAC (Rh and/or Rc and C
terminals) of the low--voltage transformer to be connected to it for proper
operation. It will not operate without these 2 connections. Rh and Rc are
connected via PCB breakout jumper. See Fig. 1. For applications using two
24VAC transformers, one in the indoor unit and one in the outdoor unit, connect
the common 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. Then, break
jumper on the circuit board. The W and HUM signals are taken from the Rh
power and the G signal is taken from the Rc power. If Thermidistat Control has
been installed in a two--transformer application that is later changed to a
single--transformer installation, 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 24VAC. They
carry a combination of power and communications data that is unique to these
products.

Models
There are programmable and non-- programmable models for all applications.
They can be configured for AC or HP installations, allowing it to be used in
place of all Bryant thermostats. Programmable thermostats may be configured as
non-- programmable if user desires.
Outdoor Temperature Sensor
The outdoor air temperature sensor is not included with the AC/HP Control. It is
available as an accessory, part number TSTATBBSEN01--B. Optimum
performance is obtained when an outdoor temperature sensor is used with the
AC/HP Control. Plan installation so that 2 wires can be run from Equipment
Control Module to an outdoor location, preferably on the north side of the house
or refer to Installation Instructions included with the outdoor temperature sensor
for simplified connection. Sensor can be mounted to outdoor unit and existing
5
dedicated sensor wires may be used for its connection. Details are provided in
sensor instructions.
Remote Indoor Temperature Sensor
A remote temperature sensor may be used with the programmable heat pump
and programmable air conditioner thermostats where it is desirable to install the
thermostat in a limited access location while measuring the temperature in the
living space. The remote room sensor may be used as a stand alone or average
with local sensor.
Two--Piece Thermostat Configuration
The Preferred Series AC/HP Control can be installed in one of two
configurations. The control may be installed as a single--piece thermostat or it
may be split into two pieces and mounted in separate locations. As a single--piece
unit, all required wiring must be brought to the Equipment Control Module for
connection to the terminal strip. In two--piece configuration, the Display Module
can be mounted in the living space while the Equipment Control Module may be
mounted near the indoor furnace or fan coil. Connection from the display to the
Equipment Control Module requires only two wires. All other control wires are
connected to the Equipment Control Module from the HVAC equipment. This
configuration results in a slimmer display and locates the Equipment Control
Module containing the switching relays away from the main living space where
relay clicking will not be heard.

1--24 — The number of months after which the Humidifier Pad Reminder icon
will be displayed, “CHECK HUM PAD”.
Default is OF (off).
Option 30 — Programmable Fan (programmable models only)
This selection allows the homeowner to program the fan selection to “Auto” or
“On” fan operation for each of the program schedule periods. This selection is
only available on programmable models.
OF (off) — Programmable fan is disabled and the homeowner must manually
select “Auto” or “On” for fan operation.
On — Programmable fan is enabled. The homeowner can program “Auto” or
“On” fan operation along with the heat and cool setpoints for each programmed
period. When the program schedule is running, the programmed heat setpoint,
cool setpoint, and fan selection for that period will be used. If the homeowner
“overrides” the programmed fan setting by pressing the fan button, the override
selection will remain in effect until the next programmed period time.
Default is OF (off).
Option 31 — Daylight Savings Time Configuration (programmable models
only)
This selection allows the installer to set the thermostat to automatically change
by one hour on the specified day, month, and week specified.
OF (off) — Daylight Savings Time Function disabled.
1,2 On — The first time the UP/DOWN button is pressed, the value of this
selection changes from OF (off) to 1. When 1 is displayed, the days of the week
and clock digits will be turned on. The installer will set the start date (Spring) for
33
Daylight Savings Time by setting the day of the week by selecting the
appropriate triangle icon next to the days of the week, the month of the year will
be set in the clock hours location (range 1 --12) and the week of the month will be
set in the clock minutes location. The week of the month selections will be F, 2,
3, 4, and L for First, 2nd, 3rd, 4th, and Last. So for the first Sunday in April, the
display would show SUN, 4, F. When 2 is displayed, the installer will then
choose the end date for daylight savings time (Fall). To activate the function, the
installer changes the “2” by pressing the up button and “On” is displayed. The
setting shall be left “On” to enable the Daylight Savings Time function.
Default is OF (off).
Option 32 — Furnace Heat Staging Control (available only when the HP
thermostat is configured to operate AC equipment).

turnoffofhigherstagesofheat.
2 — Thermostat will control the W1 and O/W2/B outputs.
Default is 1.
Option 33 — Single or Two--Piece Installation
This configuration allows the thermostat to compensate for the amount of heat
generated by the thermostat electronics to allow more accurate sensing of the
temperature sensor. The amount of heat compensation will be different between
single installation and two--piece installation.
Range: 1P or 2P
1P — The installation is single piece.
2P — The installation is two separate pieces.
Default is 2P.
34
Option 99 — Reset to Factory Defaults
Use this capability to reset the stat to “out of the box” conditions. BEWARE! All
configuration settings, program settings, clock, and calendar which have been
manually entered will be lost!
When this option is selected, the configuration number (99), will appear on the
left and 10 will appear on the right. To perform the reset, first use the MODE key
to move the box from the 99 to the 10 (programmable model) or to flash the 10
(non--programmable model). Then press and hold the DOWN key. The 10 will
start counting down toward zero. If the DOWN key is kept pressed until the
count reaches zero, the reset will be performed. When the value reaches zero, the
heat setpoint shall display -- --. The cool setpoint shall display -- and the room air
temperature shall 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 key is released early, the number will return to 10 and the reset will not
occur.
35
SYSTEM START--UP AND CHECKOUT
The AC/HP Control is designed with a built--in installer test capability. It allows
easy operation of equipment without delays or setpoint adjustments to force
heating or cooling. To enable installer test mode, press and hold the fan button
for 15 seconds. After 10 seconds, the thermostat will enter Configuration Mode.
Continuing to hold the Fan button through 15 seconds will cause the thermostat
to enter Installer Test Mode. Pressing the Mode button will change the system
operating mode to test the heating and cooling equipment. 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.
Heat -- The first stage of heating will be energized for three minutes, then the first
and second stages (if a second stage exists) will turn on for an additional three
minutes. During the first stage of heating, the HEAT ON icon will be displayed.
The “auxiliary heat on” icon will be displayed if the second stage is electric heat
(HP unit type). For heat pump installation, only 1 stage of auxiliary heat is
available. Any staging of auxiliary heat must be managed by the furnace or fan
coil. At the end of the equipment cycle the MODE will return to OFF. The
display will count down from 180 seconds to 0 for each stage when the
equipment is energized. The test of a heating or cooling cycle can be terminated
before the timer expires by pressing the MODE button and changing the system
mode to OFF.
Installer test for cooling is the same as described for heating above. COOL ON
will be displayed during cooling in Installer Test Mode. In a heat pump
application, 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.
36
TO TEST FAN
Fan button switches FAN icon between AUTO and On. While On is displayed,
G output will be energized, turning fan on. Allow up to 10 sec after button is
pressed for fan to turn on and off. On some fan coils, fan continues to operate for
90 sec after G signal is removed.
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, or AUTO to provide desired operation of heating, cooling, or
auto.
On the programmable models, the default setpoints and programmed schedule
conform to the Energy Starr requirements of the U.S. Department of Energy for
both heating and cooling. These provide energy saving temperature settings.
Refer to Table 1.
Table 1 – Energy Star Default Schedule
SCHEDULE HEAT COOL
Wake 6:00 AM 68_F 78_F
Day 8:00 AM 60_F 85_F
Evening 5:00 PM 68_F 78_F
Sleep 10:00 PM 60_F 82_F
If the programmed schedule is to be used, make sure the triangle icon next to the
FOLLOW SCHEDULE icon is turned on. Pressing the Schedule button will
cycle the triangle icon through the FOLLOW SCHEDULE, HOLD and
VACATION selections.
37
If fixed temperatures are desired, use SCHEDULE button to turn on arrow icon
next to HOLD. This will maintain setpoints, not allowing them to change with
programmed schedule.
The FAN button may be used to select between AUTO (fan on only with
equipment) and On (fan on continuously) fan modes. For further information on
temperature selection and programming, refer to Homeowner’s Guide.
Setting The Clock, Calendar, Daily Schedule, and V acation
Settings (programmable models only)
To set the clock, press the SET button once. The Clock will be displayed at the
bottom center of the screen. Use the soft keys to move the box around the digits
to be set and the UP/DOWN buttons to change the setting. Concurrent presses of
the set button will cycle through the calendar, daily schedule, and vacation
settings.
Calendar may be changed by using the soft keys to select the Month, Day, or
Year. The UP/DOWN buttons are used to change the Month, Day, or Year setting
when the box surrounds it. Day of the week (Mon--Sun) is determined by
calendar settings and is not directly adjustable.
When changing daily schedule settings, the soft keys are used to set the days,
period times, heating setpoints, and cooling setpoints. The UP/DOWN buttons
are used to change the setting with the box around it. ALL PROGRAM
PERIODS (WAKE, DAY, EVE, SLEEP) MUST OCCUR WITHIN THE SAME
24 HOUR PERIOD.
When changing Vacation settings, the soft keys are used to choose the selection
to be adjusted and the UP/DOWN buttons are used to change the setting.
38
Vacation (programmable models only)
A vacation selection is available specifically for times where the home will not
be occupied for an extended period. Vacation mode has an automatic hold,
meaning that setpoints 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 home in the selected mode, but not
comfort. When vacation mode is active, an arrow will be displayed beside
“VACATION” in the upper left corner of the display.
Vacation Setpoints
A special set of temperature setpoints exist which are active in vacation mode.
They are adjustable by the homeowner, are exclusively for vacation mode, and
are remembered from one vacation selection to the next. See Table 2 for default
values.

OPERATIONAL INFORMATION
Timers
Five--Minute Compressor Timeguard
This timer prevents compressor from starting unless it has been off for at least 5
minutes. It can be overridden for 1 cycle by simultaneously pressing FAN and
UP buttons.
39
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 much time must elapse from the start of one cycle before
another cycle can start. It serves to impose the cycles per hour limits. It 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
turning on until preceding 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.
Defrost
Detection of defrost will not work properly if the installer has configured the
O/W2/B output to function as a B output. During heat pump heating, a defrost
signal shall be considered valid if the compressor output is energized and the
defrost signal has been active for less than 15 consecutive minutes. Any defrost
signal present for longer than 15 minutes shall be considered invalid.
Heat pump/fan coil systems shall use this input to:
S Detect that defrost is in progress and energize the auxiliary heat to
provide homeowner comfort during the defrost cycle
S Allow a defrost cycle to run to completion regardless of the system
demand
40
Three--Minute Minimum on Time
In normal operation, when a stage turns on, it will not turn off for a minimum of
3 minutes. If the setpoint is changed, this timer is canceled, allowing the
equipment to turn off immediately when the demand is removed.
Heat/Cool Setpoints (Desired Temperature)
A minimum difference of 1_F and maximum of 6_F is enforced between heating
and cooling desired temperatures. This is done by allowing 1 setting to “push”
the other, to maintain this difference. This difference is adjustable via
Configuration Option 11.
Equipment On Indicators
When cooling equipment is on, a COOL ON icon is displayed. While cooling
equipment operation is delayed by the timeguard or cycle timer, COOL ON will
flash.ThesameistrueforHEATON.
During second stage compressor operation a “2” will be displayed with the
HEAT ON or COOL ON icon. This is displayed when the thermostat is
configured as H2, A2, or h2.
When the W is energized in a heat pump or Hybrid Heat system, the auxiliary
heat on icon will be displayed.
Auto Changeover
When auto changeover mode is selected, a change from heat to cool (or vice
versa) will not occur until an opposite mode demand has existed for 20 minutes.
If setpoint is changed, 20--minute requirement is deleted.
Emergency Heat Mode
When AC/HP Control is configured as a heat pump and emergency heat is
selected, all Y signals are locked out, and W becomes energized upon a call for
heat.
41
Programmable Fan (programmable models only)
The fan output can be programmed based on period of the day. When
programming for each day and period the fan can be set to On or AUTO.
Dry Co ntact
On the programmable models, the dry contact that can be used for control of an
auxiliary device. The dry contact may be configured to be closed for a specific
number of minutes per hour for each period of the program schedule. This can
be used to operate a ventilator, damper, system blower, or other auxiliary device.
There are two terminals, D1 and D2.
If it is desired to operate a ventilator or other device, the D1 and D2 terminals
can be connected directly to the equipment. This will provide a closed contact
for the specified number of minutes per hour. See Option 19.
If timed control of the system blower is required, the dry contact can be used for
this function. The G terminal can be connected to one of the dry contact
terminals with the other terminal being connected to Rc and/or Rh for timed
control of the fan. Note that this is not the same as programmable fan Option 30.
See Wiring Diagrams for more information.
42
TROUBLESHOOTING
If the display module doesn’t power up after power is applied, check the Rc/Rh
and C terminals for 24VAC. If 24VAC is present, check the voltage between Vg
and V+. This voltage will be approximately 12 --20VDC. If voltage is present,
check the polarity to make sure it is wired correctly. The display will not power
up if polarity is reversed.
Error Codes
“-- -- ” -- If AC/HP Control cannot properly read room temperature, display will
indicate “-- --” and all outputs (except fan, if on) will turn off. In the case where
the installer has selected to average the local sensor and the remote room sensor,
the AC/HP display will alternate between “-- --” for the failed sensor and the
temperature sensed by the working sensor every 10 seconds. The control will
operate from the temperature sensed by the working sensor.
E1 -- If the Display Module and the Equipment Control Module cannot
communicate via two--wire connection, an E1 will be displayed.
E2 --ThereisnoE2errormessage.
E3 -- If AC/HP Control cannot properly read outdoor temperature, and it is
needed for proper operation, display will indicate “----” in the outdoor
temperature location.
E4 -- If AC/HP Control’s internal memory fails, E4 will be displayed. Replace
AC/HP Control.
Table 3 can be used as a troubleshooting tool for determining which outputs will
be active for a particular configuration and each operating mode.
