AUTO CHANGEOVER

With auto changeover, the controller automatically switches itself from heating to cooling, or vise versa, based on the setpoints. When setting up the controller you have to enter both a cooling setpoint and a heating setpoint. The controller will also prevent the user from setting the cooling setpoint lower than the heating setpoint. Mode is set to AUTO for this operation to work.

→ SETTINGS → AUTO CHANGEOVER

Auto Changeover Time - This setting sets the minimum off time before the

controller can change from one mode to another. Default is 10 minutes. Range is from 5-120 minutes in 5 minute increments. Pressing the Right and Left buttons together for 3 seconds will over ride this delay for one cycle.

Auto or Manual Change – Default is AUTO. If MANUAL is chosen, you

will need to change from heating to cooling or vise versa. When MANUAL is set, AUTO is removed from the MODE screen as a choice.

INTERMITTENT FAN

MENU → SETTINGS → INTERMITTENT FAN Temperature conditions can vary widely between the controller location and extremities of the space the controller serves. This air stratification problem can be especially pronounced during mild outdoor conditions when long periods elapse between space conditioning demands from the controller. This intermittent fan operation can also improve the performance of air cleaning or special filtration systems that locate the cleaning or filtration media at the return air side of the fan.

DEALER INFO

INSTALLER

INFORMATION /

Improper wiring or installation may damage controller. Wiring must conform to local and national electrical codes

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.

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.

7. Use minimum of 22-gauge wiring, 18-gauge is recommended, for basic controller wiring. Shielded twisted pair should be used for optional remote indoor and outdoor sensors. Connect wires to proper terminal of the connector block in the front plastic.

8. Push any excess wire back into wall. Excess wire inside the controller plastic case can interfere with proper air flow across the temperature sensor. Seal hole in wall to prevent air leaks. Leaks can affect operation.

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 2 differential in HEAT PUMP is the AUX setting.

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.

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.

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.

OUTDOOR SENSOR

If the system is equipped with an optional outdoor temperature sensor, 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(1125-

50), 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.
