Braeburn 1025NC Non-Programmable Thermostat

Quick Guide

The Braeburn 1025NC is a non-programmable thermostat designed for single-stage heat-only systems. It requires 24 Volt AC power or two AA alkaline batteries for operation. If using 24V AC power, batteries can serve as a backup. Always turn off power to the heating equipment before beginning installation.

Product Overview

The thermostat features a digital display showing room temperature, set temperature, and system status. Controls include a System switch (OFF/HEAT) and a Fan switch (AUTO/ON). A reset button is located on the front for restoring factory defaults.

Installation

Follow these 5 basic steps to install your thermostat:

1. Install the Sub-Base: Remove the sub-base from the thermostat body. Drill 3/16 inch pilot holes and mount the base using supplied anchors.
2. Provide Power: Connect the common side of the transformer to the C terminal for 24V AC power. Alternatively, insert two AA alkaline batteries in the rear housing.
3. Connect Your Wires: Connect wires according to the terminal functions (R, G, W1, V3, C).
4. Set Installer Switches: Configure the F/C and HE/HG switches based on your system requirements.
5. Attach Thermostat: Line up the body with the sub-base and push until it snaps into place.

Wiring Connections

The terminal functions are as follows:

• R: Power Connection (24V AC or Millivolt)
• G: Fan Control
• W1: Conventional Heat Control
• V3: Zone Valve Power Close
• C: 24 Volt AC Transformer Common

Installer Switches

Adjust these switches before attaching the thermostat to the sub-base:

• F/C: Select F for Fahrenheit or C for Celsius.
• HE/HG: Select HG for gas heat or hydronic systems without a fan; select HE for electric heat or hydronic systems with a fan.

Note: Press the reset button after changing installer switches.

Operation

Use the switches on the front of the unit to control your system:

• System Switch: Set to HEAT to operate the heating system or OFF to turn it off.
• Fan Switch: Set to AUTO for the fan to run only when required by the system, or ON for continuous fan operation.
• Temperature Adjustment: Use the arrow buttons to adjust the set point temperature.

Maintenance

If batteries are installed, a low battery indicator will appear on the display when they need replacement. Replace batteries annually or if the thermostat will be unattended for an extended period. To clean, use a soft damp cloth; never spray liquid directly on the thermostat or use abrasive cleansers.

System Testing

Do not short across terminals to test the system. To test: move the System switch to HEAT, raise the set temperature 3 degrees above room temperature, and verify the system starts. Move the Fan switch to ON to verify the fan starts, then back to AUTO to stop it.
