Installation

Warning Disconnect power before beginning installation.

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

Install the Sub-Base

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

NOTE: After sub-base installation, you may insert the quick reference card into the slot on the top of the base.

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.
• For primary or backup 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.

Attach Thermostat to Sub-Base

1. Line up the thermostat body with the sub-base.
2. Carefully push the thermostat body against the sub-base until it snaps into place.
3. Insert a quick reference card into the slot on top of the thermostat.

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.

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 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

Setting User Options

Advanced User Options
User options allow you to customize some of your thermostat features. Most users will not need to make any changes to the settings in this section. To enter the User Options menu, hold down both buttons for approximately 3 seconds until the screen changes and displays the first User Option. Press the or button to change the setting for the displayed User Option. After you have made your desired setting, press together to advance to the next User Option. The thermostat will return to normal mode after your last user option is made or after no keys have been pressed for 15 seconds

Table of User Options

No.	User Options	Factory Default	Setting Options	Comments
1	1st stage differential	0.5	0.5, 1.0 or 2.0	Select a 1st stage temperature differential of .5˚, 1˚ or 2˚F (.2˚, .5˚ or 1˚C)
2	2nd stage differential (1220 Only)	2.0	1.0, 2.0, 3.0, 4.0, 5.0 or 6.0	Select a 2nd stage temperature differential of 1˚, 2˚, 3˚, 4˚, 5˚ or 6˚F (.5˚, 1˚, 1.5˚, 2˚, 2.5˚ or 3˚C)

Detailed Explanation of User Options: Temperature Differential

(User Option 1 and 2)
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).

Operating Your Thermostat

Setting the System Control Mode
The System Control has several modes of operation that can be selected by moving the SYSTEM switch to the appropriate position. COOL Only your cooling system will operate OFF Heating and cooling systems are off. HEAT Only your heating system will operate. Additional Switch Position (Model 1220 Only): EMER Operates a backup heat source (Emergency Heat) for heat pump systems only.
NOTE: If your model 1220 was configured for a conventional system (CONV) then you will not have the EMER (emergency heat) option and “NO EMER SET” will flash in the display if EMER is selected with the system switch.

Setting the Fan Control Mode

The Fan Control has 2 modes of operation – AUTO and ON. The mode can be selected by moving the FAN switches to the appropriate position. AUTO The system fan will run only when your heating or cooling system is running. On The system, the fan stays

Temperature Adjustment

Press the or button to adjust the current set point temperature.

Status Indicators

Status indicators appear in the display to let you know if your system is heating, cooling or off.
HEAT ON Indicates your heating system is running.
COOL ON Indicates your cooling system is running.

Additional Status Indicators (Model 1220 Only)
AUX Indicates that the auxiliary stage of heating is running (Multi-Stage Systems only).
EMER Indicates that the emergency heating system is running (Heat Pump Systems only).

Resetting the Thermostat
This thermostat provides you with a reset button that will erase all of your user settings. To reset the thermostat, use a small object such as a toothpick or paperclip and gently press the button located inside the small hole on the front of the thermostat housing labeled “reset”.

Additional Operation Features
Compressor Protection
This thermostat includes an automatic compressor protection delay to avoid potential damage to your system from short cycling. This feature activates a short delay after turning off the system compressor.

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

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

Thermostat Cleaning

Never spray any liquid directly on the thermostat. Using a soft damp cloth wipe the outer body of the thermostat. Never use any abrasive cleansers to clean your thermostat For troubleshooting tips, visit braeburnonline.com
