System Testing

• Possible electric shock or damage to equipment can occur.

• Disconnect power before beginning installation.

Caution

This thermostat requires 24 Volt AC Power or 2 properly installed “AA” Alkaline

batteries for

proper operation. If connecting this thermostat to a Wi-Fi network,

a 24 VAC common (C wire) may be required (see page 3). Thermostat installation

and all components of the system shall conform to Class II Circuits per NEC code.

For use only as described in this manual. Any other use will void warranty.

Model number is located on back of thermostat.

See Wi-Fi Setup Guide for Wi-Fi Setup Instructions

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.

Installer Guide 2

Install your new Braeburn thermostat in 4 basic steps:

1Install the Sub-Base

2Provide Power

3Connect Your Wires

4Attach 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:

Warning

Disconnect power before beginning installation.

Installation and Wiring

Drill 3/16” pilot holes in your

desired location. Use supplied

anchors for drywall or plaster.

3 Installer Guide

Provide Power

24VAC Power Terminal (C)

• 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.

• If connecting this thermostat to a Wi-Fi network, a 24 VAC common (C wire) is required for the

following system types:

- Heat Only

- Cool Only

- Single Stage Heat Pump

- Multistage Heat Pump

NOTE: If a common “C” wire is not being used, the 2 “AA” batteries must be installed.
