1. Safety Information
Please read all instructions carefully before installing or operating this thermostat. Failure to follow these instructions could result in property damage, personal injury, or death.
- Always turn off power to the heating/cooling system at the main fuse or circuit breaker panel before installation or servicing.
- This thermostat is designed for 24 Volt AC or 2 AA alkaline battery operation. Do not use on circuits exceeding specified voltage.
- All wiring must conform to local electrical codes and ordinances.
- Do not short (jumper) across terminals on the gas valve or at the system to test the thermostat. This will damage the thermostat and void the warranty.
2. Product Overview

3. Installation and Setup
3.1 Pre-Installation Checklist
- Ensure power to the HVAC system is OFF at the circuit breaker.
- Gather necessary tools: screwdriver, wire strippers, drill (if mounting new holes).
- Confirm your system type is compatible (single stage heat/cool, heat pump, or millivolt).
3.2 Mounting the Thermostat
- Remove the old thermostat. Note the wire connections before disconnecting.
- Separate the new thermostat from its sub-base.
- Position the sub-base on the wall. It can be mounted to a horizontal junction box.
- Mark the mounting holes and drill if necessary.
- Secure the sub-base to the wall using the provided screws.
3.3 Wiring Instructions
Connect the wires from your HVAC system to the corresponding terminals on the thermostat's sub-base. Refer to your old thermostat's wiring or your HVAC system's manual for specific wire functions. Common terminals include R, C, W, Y, G, O, B.
Typical Wiring (Consult HVAC manual for specifics):
- R: 24V AC Hot
- C: 24V AC Common (optional, for continuous backlight)
- W: Heat Relay
- Y: Cool Relay
- G: Fan Relay
- O/B: Reversing Valve (Heat Pump systems)
3.4 Battery Installation
If not using 24V AC power, or for battery backup, insert two fresh 'AA' alkaline batteries into the battery compartment on the back of the thermostat. Ensure correct polarity (+/-).
3.5 Initial Configuration Switches
On the back of the thermostat, locate the configuration switches:
- F°/C° Switch: Selects Fahrenheit or Celsius temperature display.
- HG/HE Switch: Selects Gas/Electric fan operation (HG for Gas, HE for Electric).
- CONV/HP Switch: Selects Conventional system (furnace/AC) or Heat Pump system.
Set these switches according to your specific HVAC system requirements before snapping the thermostat onto the sub-base.

4. Operation
4.1 Setting the Temperature
Use the UP and DOWN arrow buttons on the right side of the thermostat to adjust the desired temperature (setpoint). The display will show the current room temperature and the setpoint.
4.2 System Mode Selection
Use the SYSTEM switch located below the display to select the desired operating mode:
- COOL: The thermostat will activate the cooling system when the room temperature rises above the setpoint.
- OFF: The heating and cooling systems are turned off.
- HEAT: The thermostat will activate the heating system when the room temperature falls below the setpoint.
4.3 Fan Mode Selection
Use the FAN switch located below the display to select the desired fan operation:
- AUTO: The fan will run only when the heating or cooling system is actively operating. This is the most common setting.
- ON: The fan will run continuously, regardless of whether the heating or cooling system is active.
4.4 Backlight Operation
The display backlight will illuminate when any button is pressed, making it easier to read in low-light conditions. It will automatically turn off after a short period of inactivity.
4.5 Reset Button
A small reset button is located on the front of the thermostat (often labeled 'RESET'). Pressing this button with a small pointed object (like a paperclip) will return all user settings to their factory default values. This can be useful for troubleshooting or starting fresh with settings.
5. Maintenance
5.1 Battery Replacement
When the low battery indicator appears on the display, replace the two 'AA' alkaline batteries promptly. To replace, gently pull the thermostat straight off the sub-base, remove old batteries, insert new ones ensuring correct polarity, and snap the thermostat back onto the sub-base.
5.2 Cleaning
Clean the thermostat's exterior with a soft, damp cloth. Do not use abrasive cleaners or solvents. Avoid spraying liquids directly onto the thermostat.
6. Troubleshooting
If you experience issues with your Braeburn 1020 thermostat, refer to the table below for common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank or dim. | Dead or low batteries; No 24V AC power. | Replace batteries. Check circuit breaker for HVAC system. Ensure C-wire is connected if using 24V AC. |
| Heating/Cooling system not responding. | System switch in OFF position; Incorrect wiring; Blown fuse in HVAC system; Compressor short cycle delay active. | Set system switch to HEAT or COOL. Verify wiring connections. Check HVAC system fuse. Wait 5 minutes for compressor delay to clear. |
| Temperature reading seems inaccurate. | Thermostat located near heat source/draft; Internal sensor issue. | Ensure thermostat is not exposed to direct sunlight, drafts, or heat sources. Press the reset button. |
| Fan runs continuously in AUTO mode. | Fan switch set to ON. | Set fan switch to AUTO. |
If problems persist after attempting these solutions, contact a qualified HVAC technician or Braeburn customer support.
