Thermostat Location

Install the thermostat approximately 5 feet (1.5m) above the floor in an area that has a good amount of air circulation and maintains an average room temperature. Avoid installation in locations where the thermostat can be affected by drafts, dead air spots, hot or cold air ducts, sunlight, appliances, concealed pipes, chimneys, and outside walls.

Install your new Braeburn thermostat in 4 basic steps:

1. Install the sub-base
2. Provide Power
3.  Connect your wires
4. Attach the thermostat to the sub-base

Install the Sub-Base

• Remove the sub-base from the body of the thermostat.
• Mount the sub-base as shown below:

Provide Power

• For 24 Volt AC power, you must connect the common side of the transformer to the C terminal on the thermostat sub-base. In dual transformer installations, the transformer common must come from the cooling transformer.
• For battery power, insert the 2 supplied “AA-type alkaline batteries into the battery compartment located in the rear housing of the thermostat. Make sure to position the Positive (+) and Negative (-) sides of the batteries correctly with the +/- symbols in the battery compartment.

11. 1st Stage Fan Control [note 3] – Selects a 1st stage fan control of either gas or electric heat.

12. Emergency Heat Fan Control [note 4] – Selects emergency heat fan control of either gas or electric heat.

13. Reversing Valve [Note 5] – Selects the output state of the O/B terminal. Select O for this terminal to be active in the cool mode or select B for this terminal to be active in the heat mode.

14. Auxiliary Fossil Fuel Heat Pump Control [note 4] – When set to electric (AE AUX), both the compressor (1st stage) and auxiliary stage(s) will run when a call for auxiliary heat is made. When set to gas (AG AUX), the compressor stage(s) will be locked out one minute after a call for auxiliary heat. NOTE: This option can be overridden if setting an auxiliary heat balance point in Option 30.

15. Compressor Power Outage Protection [notes 3, 6] – Selects power outage protection on or off. When enabled, this thermostat will provide cold weather compressor protection by locking out the compressor
    stage(s) of heating for a period of time after a power outage greater than 60 minutes.

16. AC Power Interrupt Warning [note 6] – When enabled, the thermostat will display an outage warning when AC power to the thermostat is lost

17. Short Cycle Protection – Selects the number of minutes the cooling compressor will be locked out after turning off. This short cycle protection is also active in the heat mode if a heat pump system was selected in Option 6.

18. Residual Cooling Fan Delay – Selects a delay for the system fan after the cooling compressor has turned off. This delay will help remove the remaining cool air from the ductwork providing additional efficiency.

19. Circulating Fan Lock – When enabled, the only user fan options available are ON and CIRC (Circulation). The AUTO option is not available with this option enabled.

20. Adaptive Recovery Mode (early recovery) [note 7] – Enables or disables the ARMTM (adaptive recovery mode) feature. During ARM, room temperature is recovered by turning on the heating or cooling before the d of the set back period. The set point temperature is changed to that of the upcoming program temperature.

21. Indoor Remote Sensor Control [note 8] – If a Braeburn® indoor remote sensor is connected during installation, the thermostat will automatically detect the sensor. When an indoor sensor is detected, you may select between thermostat only (I SENS), remote sensor only (E SENS) or combine the thermostat and the remote sensor (A SENS). NOTE: This option does not apply to a Braeburn outdoor sensor. When an outdoor sensor is connected the thermostat automatically recognizes it and no further configuration is necessary.

22. Lockout Security Level – Selects the level of keypad lockout when the thermostat is locked. Level 2 locks the entire thermostat (including the front reset button). Level 1 locks everything except the SpeedBar®
    allowing for up and down temperature adjustment. NOTE: The lock code is set in the User Settings mode (see User Manual).

23. Humidification Mode – For use with an external humidifier. Selects between disabling humidification (OFF), dependant control (DEP) or independent control (IND). The DEP setting controls humidification only during a call for heating. The IND setting allows humidification output in the heat mode but does not require a call for heating. NOTE: It is recommended 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 OFF or DEP setting.

24. Auto Humidity Set Point Limit [notes 9, 11] – Select between turning the automatic humidity set point limit to auto (AUTO) or manual (MAN). When AUTO is selected, humidity control is provided automatically based on the outdoor temperature. Selecting MAN allows you to manually control the level of humidity.

25. Dehumidification – Selects between dehumidification disabled (OFF), dependent dehumidification (DEP) or independent dehumidification (IND). (DEP) If the humidity level is above the humidity set point, cooling stays on until the humidity level drops below the set point or when the over-cooling limit is reached in installer setting 26. (IND) For use with an external dehumidifier. When the humidity level rises above the dehumidification set point, both the G (Fan) and D terminals are activated. Installer setting 27 sets if D is normally active or inactive.

26. Dehumidification Over Cooling Limit [note 10] – Select the number of degrees the system is allowed to over-cool in attempting to reduce humidity.

27. Dehumidification Terminal (D) Output – Select a normally inactive relay (NI) or a normally active (NA) relay. This setting can be used in independent or dependent modes and can also be used for dehumidification fan speed control.

28. Auto Changeover Dead Band [note 11] – When Auto Changeover mode is enabled in option 5 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 the amount of this dead band in degrees with the default being 3° F.

29. Compressor Balance Point [notes 4, 12] – Locks out the use of the compressor heat stage when the outside air temperature is less than the selected setting of 15° F to 50° F (-9° C to 10° C).

30. Auxiliary Heat Balance Point [notes 4, 12] – Locks out the use of the auxiliary heat stage when the outside air temperature exceeds the selected setting of 70° F to 40° F (21° C to 4° C). NOTE: This balance
    point overrides the fossil fuel compressor lockout in option 14. If this option is set to gas and the outdoor

31. Outside Air Intake [note 13] – Selects economizer control options. Select between disabled (NONE), economizer mode (ECON) and time of day (TOD) mode.

32. Heat Set Point Upper Limit – Selects the heating set point upper adjustment limit.

33. Cool Set Point Lower Limit – Select the cooling set point lower adjustment limit.

System Testing

Warning Read Before Testing

•  Do not short (or jumper) across terminals on the gas valve or at the heating or cooling system control board to test the thermostat installation. This could damage the thermostat and void the warranty.
• Do not select the COOL mode of operation if the outside temperature is below 50º F (10º C). This could possibly damage the controlled cooling system and may cause personal injury.
• This thermostat includes an automatic compressor protection feature to avoid potential damage to the compressor from short cycling. When testing the system, make sure to take this delay into account.
  NOTE: The compressor delay can be bypassed by pressing the reset button on the front of the thermostat.

All user settings will be returned to factory default, however, all Installer settings will remain as originally programmed in section 4.
