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 5 basic steps:

1. Install the Sub-Base
2. Provide Power
3. Connect Your Wires
4. Set Installer Switches
5. Attach Thermostat to Sub-Base

1. Install the Sub-Base:
   • Remove the sub-base from the body of the thermostat.
   • Mount the sub-base as shown below:Drill 3/16" pilot holes in your desired location. Use supplied anchors for drywall or plaster.
     
     NOTE: After sub-base installation, you may insert the quick reference card into the slot on the top of the base.
     
2. Provide Power
   
   24VAC Power Terminal (C)
   
   • For 24 Volt AC power, you must connect the common side of the trans- former to the C terminal on the thermostat sub-base.
   • For primary or back-up 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.
3. Connect Your Wires

System Testing

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.

1. Move the SYSTEM switch to HEAT mode.
2. Press to raise the set temperature a minimum of 3 degrees above the current room temperature. The system should start within a few seconds. With a gas heating system, the fan may not start right away.
3. Move the SYSTEM switch to the OFF mode. Allow the heating system to fully shut down.
4. Move the SYSTEM switch to the COOL mode.
5. Press to lower the set temperature a minimum of 3 degrees below the current room temperature. The system should start within a few seconds (unless compressor short cycle protection is active – See note above).
6. Move the SYSTEM switch to the OFF mode. Allow the cooling system to fully shut down.
7. Move the FAN switch to the ON mode. The system fan should start within a few seconds.
8. Move the FAN switch to the AUTO mode. Allow the system fan to turn off.

Table of User Options

Detailed Explanation of User Options

Programming Mode

(User Option 1)
Selects the programming mode (choose from 7 day, 5-2 Day (weekday/ weekend) programming or non-programmable.

Temperature Differential

(User Option 2 and 3)
The differential setting is the temperature control range that your thermostat will provide. The smaller the setting, the tighter your range of temperature control and comfort will be. The 2nd stage differential is only for systems with a second stage of heating (auxiliary heat).

Extended Hold Period

(User Option 4)*
The Extended Hold Period lets you select the period your thermostat will hold the temperature when the HOLD mode is activated (See "Temperature Adjustment"). When LNG is selected the thermostat will hold your temperature indefinitely. When 24HR is selected, the thermostat will hold your temperature for 24 hours and then return to the current program at that time.

Service Filter Monitor

(User Option 5)
The Service Filter Monitor is a user selectable service monitor that will display a reminder for a required air filter replacement by flashing the SERVICE FILTER segment in the display. When the selected interval has been reached, and required cleaning or replacement has been performed, touch the RETURN button to reset the timer and reset the service monitor. Select OFF or a set number of days before the reminder will appear.

Adaptive Recovery Mode (early recovery)

(User Option 6)*
Adaptive Recovery Mode is a user setting that controls when the thermostat will start to recover from setback.

*Not available if User Option 1 is set to non-programmable

Thermostat Maintenance

Changing the Batteries

Depending on your particular installation, this thermostat may be equipped with two (2) "AA" type alkaline batteries.

If batteries are installed and they become low, a low battery indicator will appear in the display. You should change your batteries immediately when you see the low battery signal by following these instructions.

1. Remove thermostat body by gently pulling it from base.
2. Remove old batteries and replace with new batteries.
3. Make sure to correctly position the (+) and (-) symbols.
4. Gently push thermostat body back onto base.

NOTE: We recommend replacing the thermostat batteries annually or if the thermostat will be unattended for an extended period of time.
