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.

• Connect Your Wires

3. Install a field-supplied jumper between the W2 and E terminals if there is no separate emergency heat relay installed. Provide disconnect and overload protection as required.

• Set Installer Switches

The Installer switches are located on the back of the thermostat and must be properly configured for this thermostat to operate properly.

NOTE: Installer switches are located on the back of the thermostat. The reset button must be pressed after making any changes to these switches.

• 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 systemhttps://manualslibraryy.com/intertek-heat-pure-1500-infrared-heating-system-user-manual/, the fan may not start right away.
3. Move the SYSTEM switch to the OFF mode. Allow them 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.
   NOTE: Installer switches are located on the back of the thermostat. The reset button must be pressed after making any changes to these switches.

• Setting User Options

Advanced User Options

User options allow you to customize some of your thermostat’s features. Most users will not need to make any changes to the settings in this section. To enter the User Options menu, hold down the RETURN button 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 RETURN 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

Detailed Explanation of User Options:

Temperature Differential (User Options 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 system with a second stage of heating (auxiliary heat).

Extended Hold Period (User Option 3)

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 4)

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 5)

During Adaptive Recovery Mode (ARM™), room temperature is recovered gradually by turning on the heating or cooling before the end of the set back period. The set point temperature is changed to that of the upcoming program temperature.

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.
