Braeburn Builder 1005 Thermostat Troubleshooting
| Problem | Solution |
|---|---|
| Thermostat does not turn on heating or cooling system. | Check to see if OFF is shown in display. This indicates that the system is turned off at the thermostat. Move the system selector switch to the ON position. |
| Compressor protection features may be in effect due to compressor short cycle conditions. | |
| Heating or cooling system may be malfunctioning. Call a professional service technician immediately to verify system operation. | |
| Thermostat turns heating or cooling system on too often or not often enough. | Increase or decrease temperature differential setting as appropriate to provide the desired performance level. |
| Low battery indicator is shown in thermostat display. | Replace batteries immediately to maintain proper system operation. |
| OFF is shown in thermostat display and heating or cooling system will not start | This indicates that the system is turned off at the thermostat. Move the system selector switch to the ON position. |
| Thermostat display is blank. | It is possible that the batteries are drained and not providing power for the thermostat to control the system. Replace batteries immediately to maintain proper system operation. If you replace the batteries and the display does not appear, call a professional service technician to verify thermostat and system performance. |
| Thermostat will not allow me to program a setpoint temperature higher than 90° F (32 e C). | This is above the normal thermostat temperature setting range of 45’ to 90 F (7 to 32° C). |
| Thermostat will not allow me to program a setpoint temperature lower than 45° F (7* C). | This is below the normal thermostat temperature setting range of 45 to 90 F (7 to 32° C). |
| Fan continues to run all the time whether the system is on or off. | Check that the fan control switch is in the AUTO position. This will allow the fan to run only when the heating or cooling system is turned on and running. |
| Check thermostat wiring to make sure that the fan control wiring is connected to the correct terminals on the wiring terminal block. | |
| The room is too warm or too cold. | verify the current setpoint and make any modifications that are necessary. |
| HI is shown in the thermostat display where the room temperature is normally displayed | The temperature sensed by the thermostat is higher than the 90˚ F (32˚ C) upper limit of the thermostats display range. The display will return to normal after the sensed temperature lowers within the 45˚ to 90˚ F (7˚ to 32˚ C) display range. This condition could occur from the system being turned off during an exceptionally warm period or upon installation when the thermostat has been stored for a long period of time in a warm vehicle or location prior to being installed. The thermostat is equipped with a mechanical high temperature safety switch that will turn off the thermostat should the temperature exceed 99˚ F (37˚ C) |
| LO is shown in the thermostat display where the room temperature is normally displayed. | The temperature sensed by the thermostat is lower than the 45˚ F (7˚ C) lower limit of the thermostats display range. The display will return to normal after the sensed temperature rises within the 45˚ to 90˚ F (7˚ to 32˚ C) display range. If the temperature in the controlled space seems to be normal, wait for the thermostat to acclimate to the correct room temperature. This condition could occur from the system being turned off during a cold weather period or upon installation when the thermostat has been stored for a long period of time in a cold vehicle or location prior to being installed. The thermostat should be allowed to warm up prior to installation to allow proper heating control once installed. |

Braeburn 229100 Thermostat Troubleshooting
| SYMPTOM | DIAGNOSTIC STEPS |
|---|---|
| No Humidifier Operation in "ON" position | 1. Set thermostat to operate both furnace burner and blower. Operation may be necessary for system power. |
| 2. Check voltage at humidifier control terminals. There should be no voltage for Power Humidifier. Voltage should be 20-30 VAC for most others | |
| 3. Inspect humidifier wiring. | |
| Humidifier operation in "ON" position only | 1. Humidity level in the home is higher than knob setting. Humidifier control will not operate the humidifier until humidity level is reduced. |
| Humidifier operation continuous | 1. When the humidity in the home is less than the knob setting, the control will operate humidifier until the humidity is higher. Reduce knob setting. |
| 2. Use "ON" position. Verify that the humidifier operates. | |
| 3. Remove wires from control terminals. If humidifier continues to operate, check solenoid valve. | |
| Humidifier turns on and off repeatedly | 1. Check voltage at humidifier control terminals. There should be no voltage for a Power Humidifier. Voltage should be 20-30 VAC for most others. |
| 2. If mounted on return air duct, make sure humidifier control is at least 24" upstream of humidifier's air discharge. |
