To deactivate a night storage heater control, you can typically do so by turning the input or output controls to the lowest setting or off position. This will stop the heater from charging and releasing heat. Additionally, you may need to switch off the power supply to the heater at the circuit breaker or fuse box. It's important to refer to the specific manufacturer's instructions for your night storage heater model to ensure you are deactivating it correctly and safely. **

The symbols on the heater control typically represent different functions and settings. For example, a snowflake symbol usually indicates the air conditioning or cooling function, while a sun symbol represents the heating function. Other symbols may indicate fan speed settings, defrost options, or air circulation modes. It's important to refer to the user manual of the specific heater model to understand the meaning of each symbol and how to adjust the settings accordingly. **

You can control an infrared heater with a sensor by using a temperature sensor to measure the current temperature of the room. Once the sensor detects that the room temperature has dropped below a certain set point, it can send a signal to the heater to turn on and start emitting infrared heat. Similarly, when the sensor detects that the room has reached the desired temperature, it can send a signal to the heater to turn off. This allows for precise and automatic control of the heater based on the actual temperature of the room, ensuring efficient and comfortable heating. **

Night storage heater charging control can be confusing for some people because it involves setting the right amount of heat to be stored during off-peak hours and released during the day. If you're having trouble understanding it, it might be helpful to consult the user manual or seek guidance from a professional. It's important to get a good grasp of how the charging control works to ensure efficient and cost-effective heating in your home. **
