Installation

Replacing Existing Thermostat
Most existing thermostats have three parts

• The cover may snap or hinge over the existing thermostat.
• The electronics or body, control 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 the existing thermostat.
2. Carefully remove the cover and electronics body from the old thermostat’s up-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.
4. After labeling the old wires, loosen each connection and remove them from the 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.

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 (three-stage heating available on heat pump systems). Do not use this thermostat on systems with a voltage higher than 30 Volts AC. This thermostat requires a transformer common wire for proper installation if used as a hardwired thermostat.

Installing New 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 13 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 e 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 13 possible connection points, you may need to apply moderate force to close the case.
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 program and system checkout.

Installer Option Descriptions

1. Selects a preferred temperature scale of either ºF or ºC.

2. 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.

3. 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 4 through 8 to their default values dependent on system selected.

4. Selects between 1st stage gas or electric heat Fan Control. This Installer Option is not available with a heat pump system.

5. Selects aux-stage gas or electric heat Fan Control. This Installer Option is only available with a 2 or 3 stage heat pump system.

6. 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. NOTE: Can be overridden by Auxiliary Balance Point. See Installer Option number 16 in the chart above for details.

7. Select between turning the AC power interrupt warning off or on. During a power loss, the thermostat will display an outage warning (-AC). All set tings will be maintained until the outage period is over. This Installer Option is only available when thermostat is installed as a hardwired unit.

8. 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 (continued on page 8).

9. This thermostat includes an automatic compressor protection feature to avoid potential damage to the compressor from short cycling. This thermostat automatically provides an adjustable delay after turning off the compressor. This protection is also present in the first stage heat mode of operation on single stage heat pump systems to protect the compressor.

10. 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.

11. The Recirculating Fan Mode provides more even temperature distribution and improves indoor air quality by circulating air through the furnace filtration system more often. The Recirculating Fan can be locked “on”, so that the only fan selections available to the user are CIRC and ON. By locking the Recirculating Fan to CIrCON, the user will only have the option to run the fan all the time (ON) or use the Recirculating Fan Feature (CIRC). When locked on, the fan circulates at a fixed time of 12 minutes on, 24 minutes off. In the CIRC mode, the fan can be set to run every 24, 40, 60 or 120 minutes
    (see chart below). The Recirculating Fan feature is available in the COOL, OFF, HEAT, or EMER mode. To set the fan run time, see page 12.

12. 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, and for 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 BACK and NEXT buttons at the same time.

13. The keypad lockout feature has two levels of security. Level one locks all buttons (including the reset) except for the , and backlight buttons. Level two 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 security level is set in the Installer Options and the lock code is set in the User Options.

14. 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.

15. Only available with multi-stage heat pump and outdoor sensor connected. Locks out the use of the compressor heat stage for outside air temperatures less than installer setting. Select from no lockout or a setting between 10º F to 50º F (-9º C to 10º C).

16. Only available with multi-stage heat pump and outdoor sensor connected. Locks out the use of the auxiliary heat stage for outside air temperatures over installer setting. Select from no lockout or a setting between 70º F to 40º F (21º C to 4º C). NOTE: This balance point overrides the fossil fuel compressor lockout. If the lockout is set to AG and the outdoor temperature is over the AUX balance point, the compressor will remain on during a second stage heating call. The unit will recover to the set point without the AUX stage.

17. Selects the heating set point upper limit, scrolls between 90º F and 60º F (32º C and 10º C).

18.  Selects the cooling set point lower limit, scrolls between 45º F and 80º F (7º C and 27º C).

Low Battery Detection and Replacement

This thermostat requires two (2) properly installed “AA” alkaline batteries to provide power for the thermostat if 24 volt AC power is not connected to the terminal block. This thermostat is equipped with
a unique, three level low battery detection feature that constantly monitors the batteries during normal operating mode to determine whether they have sufficient power to provide proper operation. When this feature determines that the battery status is low, a low battery indicator will appear in the display. After 30 days the battery indicator will start to flash, and after 60 days the battery indicator will begin to flash faster, indicating that the batteries need to be replaced immediately to maintain system operation and program settings.

Replacing the Batteries

1. Open the front cover and locate the battery compartment door.
2. Remove the two “AA” alkaline batteries located in the battery compartment.
3. Install two new “AA” alkaline batteries into battery compartment. Make sure to match the positive (+) ends of the batteries with the positive (+) terminals located in the battery compartment.
4. Close battery compartment. The low battery indicator should no longer
   appear in the display.

Non-Volatile Memory
In the event of a power failure or battery removal, the Non-Volatile Memory Feature allows all settings to be recovered, eliminating the need to reset the temperature and various user/installer settings. When AC power is restored after an outage or batteries are reinserted, all settings are retrieved from memory and reinstated.

Status Indicators
Three status indicators can be displayed to notify you of key system information.

AUX:  This will turn on when the auxiliary stage of heating is active. The auxiliary stage of heating is usually the least economical stage of heat.

CHECK: Indicator will be displayed when a malfunction occurs in a heat pump system. When this indicator is active, call a professional service technician to verify system performance and switch the system to Emergency Heat mode if required to maintain room temperature.

EMER (displays only on heat pump systems): An indicator will be displayed when the Emergency Heat Mode of operation is selected using the system selector button. When selected, the heat pump stage of heat is turned off and the emergency (auxiliary) stage of heating is used to maintain the set point temperature.

To provide time to verify equipment operation, a test will run for 5 minutes. At the end of that time, the thermostat will return to normal operating mode. To stop a test early press BACK and NEXT at the same time for 3 seconds.
NOTE:  Only tests that apply to the current thermostat settings will be displayed. As an example, tests for 3rd stage compressor will not be available on a thermostat configured for a 2 stage conventional system. *Notes on Fan (G Terminal) Function: The G terminal will only be active if the stages are configured as electric heat. Systems that have the heating stages  configured as gas will not activate the fan (G) termina

Troubleshooting

• Symptom: Thermostat does not turn on heating or cooling system. Potential Solution: Check to see if OFF is shown in display. This indicates that the system is turned off at the thermostat. Change the system to HEAT or COOL. After the compressor short cycle protection period expires, the system should start. Compressor protection feature may be in effect due to compressor short cycle conditions. See page 13.
  Heating or cooling system may be malfunctioning. Call a professional service technician immediately to verify system operation.

• Symptom: Thermostat turns on heating instead of cooling or cooling instead of heating. Potential Solution: Check thermostat wiring to make sure that the heating and cooling stages are connected to the correct terminals on the wiring terminal block. See section 9, Wiring Diagrams.

• Symptom: Thermostat turns heating or cooling system on too often or not often enough. Potential Solution: Increase or decrease temperature differential settings as appropriate to provide the desired performance level. See page 9.

• Symptom: Low battery indicator is shown in the thermostat display. Potential Solution: Replace batteries immediately to maintain proper system operation. See page 14.

• Symptom: Thermostat display is blank. Potential Solution: It is possible that AC power is not present at the thermostat and/or the batteries are drained. Check fuse, circuit breaker and thermostat wiring as appropriate to verify AC power is available. Replace batteries before reprogramming thermostat. See page 14. If AC power is present, call a professional service technician to verify thermostat and system performance.

• Symptom: The room is too warm or too cold. Potential Solution: Review current set point and change as necessary. See page 12.

• Symptom: Fan runs intermittently or when system is off. Potential Solution: Fan switch is in Recirculate Mode (CIRC).

• Symptom: HI is shown in the thermostat display. Potential Solution: The temperature sensed by the thermostat is higher than the 99˚ F (37˚ C) upper limit of the thermostats display range. The display will return to normal after the sensed temperature lowers within the 40˚ to 99˚ F (4˚ to 37˚ C) display range. Turn on the cooling system or use other methods to lower the temperature accordingly. This condition could occur from the system being turned off during an exceptionally warm period or upon installation when the thermostat has been stored for a long period of time in a warm vehicle or location prior to being installed.

• Symptom: LO is shown in the thermostat display. Potential Solution: The temperature sensed by the thermostat is lower than the  40˚ F (4˚ C) lower limit of the thermostat’s display range. The display will return to normal after the sensed temperature rises within the 40˚ to 99˚ F (4˚ to 37˚ C) display range. Turn on the heating system to raise the temperature as needed for comfort within the room.
  This condition could occur from the system being turned off during a cold weather period or upon installation when the thermostat has been stored for a long period of time in a cold vehicle or location prior to being installed. The thermostat should be allowed to warm up prior to installation in order to provide proper heating control once installed.

• Symptom: Cannot program a set point temperature higher than 90˚ F (32˚ C). Potential Solution: This is above the normal thermostat temperature setting range of 45˚ to 90˚ F (7˚ to 32˚ C).

• Symptom: Cannot program a set point temperature lower than 45˚ F (7˚ C). Potential Solution: This is below the normal thermostat temperature setting range of 45˚ to 90˚ F (7˚ to 32˚ C).

• Symptom: Thermostat will not allow me to change the set point. Potential Solution: The keypad is locked. Press and hold the and buttons at the same time to enter unlock mode. Press to enter the 3 digit unlock code. Press the NEXT button to move to the next digit.

• Symptom: Fan continues to run all the time whether the system is on or off. Potential Solution: Check to make sure the fan control switch is in the AUTO position. This will allow the fan to run only when the heating or cooling system is turned on and running. Check thermostat wiring to make sure that the fan control wiring is connected to the correct terminals on the wiring terminal block. See section 9, Wiring Diagrams.

• Symptom: CHECK is shown in thermostat display. Potential Solution: Switch to emergency heat if heat is required. Contact a professional service technician to verify thermostat and system performance.
