Remote Control

Innovative Temp sensor remote control

The remote control features a built-in independent temperature sensor, detecting the temperature around it and transmitting signals to the heater in real-time. It is no longer limited to the heater's own sensor or the temperature around the device.

How to use

1. "Remote 80" below the remote screen indicates the temperature sensed by the remote. It updates every minute and syncs in real-time with the heating device, which uses this temperature to determine when to start or stop heating.
2. The remote's temp sensor is in the hole at the back. Do not block the hole.
3. Place the remote where you want to achieve the target temperature.
4. Stand the remote upright for more accurate temp sensing.
5. If the remote loses power or the heating device cannot receive the remote's temp signal for over 3 minutes, the device will switch to sensing the ambient temp via the built-in wire sensor.

Note

• Changes made on the app or the device won't sync with the remote screen.
• Each time you press the remote, the product will follow the settings displayed on the remote screen.
• If the remote, app, and device are all used to make adjustments, the last method used will take precedence.

Main function

Sense mode (40-86°F/5-30°C)

• The default value is 86°F/30°C in the first using.
• Sense the changes in ambient temperature and heat up rapidly, which is suitable for most situations.

ECO mode (40-86℉/5-30℃)

• The default value is 77°F/25 °C for the first use.
• More sensitive optimization of heating power, suitable for power - saving scenarios.

Digital Inverter Technology

• Based on multi - sensor temperature sensing and change detection, intelligent digital inverter algorithm.
• Stepless and smooth power adjustment, automatically optimized to the best power.

Troubleshooting

Why does the heater not heat?

A: Please check below 4 possible situations and solution: 1) Overheating protection — Please check the reset button on the back of the device. 2) Tip-over protection — Please ensure that the product is upright. 3) Ensure that your circuit breaker or fuse is working properly. 4) The temperature value set by the heater is lower than temperature of sensor, please adjust to higher.

What does it show E1/E2/E3/E4 on display?

A: The error code is concerned to different troubles, please contact us at support@ballu.com.

Why does the room warm up slowly?

A: It is recommended to close doors and windows to prevent heat loss during using and work at Sense mode (86°F) and wait for the room to warm up before setting to your desired temperature. This helps to warm up the room faster and reduces energy consumption as the room enters a state of insulation.

Why does the heater shutdown suddenly?

A: Please check below 3 possible situations and solution: 1) Overheating protection — Please check the reset button on the back of the device. 2) Tip-over protection — Please ensure that the product is upright. 3) Power cord is not properly plugged in - Connect the plug to a powered electrical outlet.

Why does it smell when I use it?

A: It is normal and harmless to have a certain odor in the first using. We recommend turning on the product in Sense mode(86°F) for 2 hours in a ventilated environment.

Why do you sometimes hear switch sounds?

A: The heater automatically switches off the heating when the set temperature on the heater is reached in the room, it is possible to hear the switch switching sound at that moment.

How is it different from an oil heater?

A: Oil heaters transfer heat through oil, resulting in excessive heat loss, low efficiency, and slow heating, which leads to lower room temperatures. In contrast, Ballu convection electric heaters use special alloy to directly heat the air without an intermediary medium, achieving high efficiency, rapid temperature increase, and uniform indoor temperatures through natural convection.

How to save on electricity bills?

A: Power usage is determined by room size, insulation, and desired temperature. Ideal for 160-220 sq ft spaces, with potential for up to 300 sq ft but longer heating times. Close doors and windows to minimize heat loss. Start at the highest setting for quick heating, then adjust to a lower temperature once the room is insulated, stabilizing temperature and reducing power consumption. Utilize different temperature modes for various times and conditions to save on electricity.
