The DIY parts for the heater have features such as two-level temperature adjustment, intelligent constant temperature, scheduled shutdown function, infrared remote control, tipping protection, and real-time temperature display.
Product detail presentation:
1) Two levels of temperature control;
You can freely adjust the temperature as needed through the buttons and remote control.
2) Support infrared remote control;
The heater can be controlled remotely.
3) Intelligent constant temperature, safe and energy-saving;
It stops working when the temperature is higher than the safe temperature and starts working when it is lower than the set temperature, which is safe and saves power.
4) It can be shut down at a scheduled time and display the temperature in real-time;
After turning on the timer function, the blue LED light will start flashing, and the main interface will display the heater’s real-time temperature and the remaining timing time.
5) Comes with dumping protection;
If the heater is accidentally touched, the anti-falling function will be triggered, the heater will automatically shut down, the red light will flash, and the buzzer will alarm.
6) Acrylic portable handle;
Compact and portable, it doesn’t take up much space. You can lift it and go at any time. It’s compact, lightweight, and easy to move around.
