INFORMATION / ADVANCED
FEATURES
SAFETY CONSIDERATIONS
Improper wiring or installation may damage controller. Wiring must
conform to local and national electrical codes
INTRODUCTION
The controller is a wall mounted, 24VAC low-voltage controller which
maintains room temperature by controlling the operation of a heating and air
conditioning system. Batteries are not required; temperature and mode
settings are preserved with the power off.
INSTALLATION CONSIDERATIONS
The controller requires no batteries. The controller is not a power stealing
device and MUST have both R and C connected.
INSTALLATION
IV.
CONTROLLER LOCATION
Controller should be mounted:
- Approximately 5 ft. (1.5m) from floor.
- Close to or in a frequently used room, preferably on an inside
partitioning wall.
- On a section of wall without pipes or duct work.
Controller should NOT be mounted:
- Close to a window, on an outside wall, or next to a door leading
to the outside.
- 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.
V.
INSTALL CONTROLLER
1. Turn off all power to unit.
2. If an existing thermostat is being replaced:
A. Remove existing thermostat from wall.
B. Disconnect wires from existing thermostat, one at a time. Be
careful not to allow wires to fall back into the wall.
C. As each wire is disconnected, record wire color and terminal
marking.
D. Discard or recycle old thermostat.
NOTE: Mercury is a hazardous waste and MUST be disposed of
properly.
3. Separate the front and back pieces of plastic.
4. Route thermostat wires through hole in back piece of plastic. Level plastic
against wall (for aesthetic value only - thermostat need not be leveled for
proper operation) and mark wall through 2 mounting holes.
5. Drill two 3/16-in. mounting holes in wall where marked.
6. Secure back plastic to wall with 2 anchors and screws provided making
sure all wires extend through hole in plastic.

OFFSETS
TEMPERATURE OFFSETS
This option allows calibration (or deliberate miscalibration) of the
room temperature sensor(s). There are various reasons why the
displayed temperature would be adjusted to a higher or lower value.
NOTE: Do not adjust for 30 minutes after installation because board
may be heated by handling. The selected number is the number of
degrees, plus or minus, which will be added to actual temperature.
The numbers can range between -5˚ and +5˚. Default values are set to
0˚ offset.
Temperature Offset
Remote Indoor Offset (if sensor is attached)
Outdoor Offset (if sensor is attached)
HUMIDITY OFFSET
This option allows calibration of the humidity sensor. Adjustments
can range between -10% and +10%. Default is 0% offset.
ANTICIPATOR
This adjustment controls the sensitivity and cycle rate of the
controller. Higher numbers decrease the cycle rate. Lower numbers
increase the cycle rate. Default value is 0, and the range is 0-9.
DIFFERENTIAL
This adjustment will vary the number of degrees, from the set point,
before a call for heating or cooling is made. Adjustments can range
between 1˚ and 4˚ differential. Default is 2˚ offset. (If your set point
is 70˚F in heating, your thermostat will not call for heat until the
temperature is 68˚F, with a 2˚ differential). 3rd stage Cool
differential is the same as 2nd stage cool differential. Third stage heat
differential in HEAT PUMP is the AUX setting.
CYCLES PER HOUR
This feature will not allow more than the specified number of equipment
cycles per hour. Values can range from 4 to 8 Factory default setting is 6.
(or 1 cycle every 10 minutes.). This default selection will provide
optimum performance in nearly all installations.
PROGRAM SETTINGS
SMART RECOVERY
Smart recovery is a feature of your controller designed to save energy by
gradually adjusting temperatures. When it’s time for a programmed
temperature change, smart recovery begins working in advance, turning
the
system on and off as needed to slowly adjust the indoor temperature.
During these transition periods, you may notice that the actual
temperature and your temperature setting don’t match. That’s smart
recovery in action, adjusting temperatures in small increments for
greater energy efficiency. This is more energy efficient than simply
allowing the system to operate at full capacity until the desired
temperature has been met. Smart Recovery helps avoid excessive use of
auxiliary heat when recovering from night setback in the heating mode.
EVENTS PER DAY
This is where you can set the number of events per
day. (An event is a period of time scheduled with a
certain heating and cooling setpoint.) For instance if
you are away from your home from 8am to 5pm,
make this period of time an event and set the thermostat at an energy
saving setting. You have the option of setting the events per day to 4RESIDENTIAL (4 events), 2-RESIDENTIAL (2 events) or 2BUSINESS (2 events). Default is 2 – BUSINESS.

in 5˚ increments.
HEAT PUMP LOCKOUT
When an outdoor temperature sensor is installed, you can set it up so the
Heat pump will not operate when the outdoor temperature is below a set
temperature. Ranges for this are NONE (default), 5˚F to 50˚F in 5˚
increments.
TEST MODE
When test mode is selected, the system can be operated in any of the
available operational modes for 30 minutes. The system will run the set
mode regardless of the temperature set point and room temperature. The
display will flash a red screen as a reminder that you are in the test
mode.
RESET TO DEFAULTS
Selecting Reset to Defaults will set all of the options to the factory default
setting with the exception of the configuration settings. The configuration
settings and the accessory internal settings need to be set and reset
individually.
TEMPERATURE RANGE
This is accessed from the Installer Settings menu and regulates the
maximum Heat and minimum Cool settings the thermostat can be adjusted
to. The factory default for occupied set-points is 74°F for Cooling and
70°F for Heating. The factory default for the minimum Cooling allowed is
70°F and the factory default for the maximum Heating is 72°F.
When operated in Auto changeover mode there is a default minimum
differential of 2°F between Cooling and Heating, so if Cooling was
adjusted down to the 70°F minimum it will force Heating to 68°F.

Bard PN 8403-061(1125-2), it is possible to allow the controller to operate
the heat pump system in the most efficient manner possible. By setting the
COOLING LOCKOUT, ELECTERIC HEAT LOCKOUT, and the HEAT
PUMP LOCKOUT you can avoid running the heat pump when the outdoor
temperature is too low to operate efficiently. You can also avoid running
the electric heat when the outdoor temperature is high enough to allow the
heat pump to maintain a comfortable temperature.
COOLING LOCKOUT is defaulted to NONE which is disabled.
Selectable range is from 40˚-55˚ in 5˚ increments.
ELECTRIC HEAT LOCKOUT is defaulted to NONE which is disabled.
Selectable range is from 5˚-60˚ in 5˚ increments.
HEAT PUMP LOCKOUT is defaulted to NONE which is disabled.
Selectable range is from 5˚-50˚ in 5˚ increments. OPERATION: If
compressor is turned off due to outdoor temperature going below set-point
while the compressor is operating it will stay off until the room thermostat
set-point is reached even if the temperature at the outdoor temperature rises
above the outdoor sensor setting. The next operating cycle will be based
on what the temperature is at the outdoor sensor at time of call for heating.
The OUTDOOR sensor is connected to the OD and GND terminals on the
controller, and when connected, the outdoor temperature is automatically
displayed on the controller screen.
REMOTE INDOOR SENSOR
Allows selection of the optional remote sensor, Bard PN 8403-062(112550), to determine indoor temperature. (NOTE: If no Remote Indoor
Sensor is connected during initial configuration process, the Remote Indoor
Sensor selection does not display in the Installer Menu. If a Remote Indoor
Sensor is connected at a later date, the controller will recognize the
connection, and the selection step will automatically be added to the
Installer Menu.) Options are REMOTE SENSOR ONLY, AVERAGE
WITH STAT, and NO REMOTE SENSOR. Selecting REMOTE
SENSOR ONLY, allows the indoor sensor to take control of temperature
sensing(if connected). Selecting AVERAGE WITH STAT, will average
the temperature of the on-board sensor to the indoor sensor, and selecting
NO REMOTE SENSOR, will use the on-board temperature sensor.
The REMOTE SENSOR is connected to the ID and GND on the controller
terminals.
24V CONTROL WIRING
All excess wire should be pushed back into the wall as far as possible. Excess
wire inside the thermostat plastic case may interfere with the air flow across
the temperature sensor.
THERMOSTAT CONNECTIONS
C – 24V Common for Control Circuit
R – 24V Supply for Control Circuit
W1/E – E Heat/ First Stage Heat
W2 – Second Stage Heat
O/B – Reversing Valve - energized in HEAT mode(B is default)
Y1 – 1st Stage Compressor / Cooling / Heating
Y2 – 2nd Stage Compressor / Cooling / Heating
Y0/D – Economizer / Dehumidifier output*
A – Ventilation Output
G – Fan
L – Input for CS2000A or compressor fault

GND – Ground **
OD – Outdoor Temperature Sensor **
ID – Indoor Temperature Sensor **
*Controller must be configured for “No Economizer”
for dehumidification control to be active
**Shielded twisted pair should be used for remote
Indoor and Outdoor Sensors to avoid any possible
interference from other electrical systems or other
external sources. The shield (drain) should be
connected to 24V Common (C) at the controller.
For specific 24V control circuit wiring refer to the Bard Low Voltage
Control Circuit Wiring manuals or the equipment installation
instructions packaged with each piece of equipment.
